A modular home is a type of residence constructed from metal, wood, or pre-cast concrete made in sections in a factory setting. Modular houses are not premade houses. The factory-built modules, called prefabricated sections or simply modules, are the walls, ceilings, and floors; once built, they are transported to a building site where they are assembled onto a permanent foundation. Premade houses are built in a factory as a complete unit and transported to the building site. Traditional construction is built entirely on-site (often referred to as “stick-built”), modular homes are largely fabricated off-site, leading to a more controlled manufacturing process. It’s often seen as a cost-effective and time-saving method of construction since it reduces delays due to weather and can streamline the building process.

While modular homes are sometimes confused with manufactured homes, the key distinction lies in the permanence of placement. Unlike manufactured homes, which are built to a federal code and can be relocated, modular homes must comply with state and local building codes and are fixed to a permanent foundation. This ensures a level of durability and safety similar to that of traditional site-built homes. Modular homes can also offer customization options for homebuyers, enabling flexibility in design to accommodate individual preferences and needs.

The energy efficiency of modular homes is another significant aspect often cited. Careful construction in a controlled environment can result in tighter joints and better air filtration, which can lead to long-term savings and contribute to a more sustainable living by reducing energy consumption. These homes also open up the possibility for modern designs and aesthetics while still providing the feel and permanence of traditional homes.

Completed in 2014, The Stack is a seven-story modular apartment building located in Manhattan’s Inwood neighborhood. Designed by Gluck+ (formerly Peter Gluck and Partners Architects), the building comprises 56 prefabricated steel-framed modules, each measuring approximately 12.5 m by 4.5 m. The modules were constructed off-site, transported to the location, and stacked using a crane, demonstrating the efficiency and speed of modular construction in a dense urban setting. The Stack showcases the potential for modular technology to address housing needs in cities while maintaining architectural quality and design flexibility.

These three projects highlight the diverse applications and styles of modular construction in various parts of the world, from residential complexes to mixed-use buildings, and spanning several decades of architectural innovation.

Why modular homes are perceived as inferior?

Modern modular home construction featuring large windows during sunset, reflecting a warm interior glow against a cloud-streaked sky.

Modular homes should not be confused with mobile homes or trailers which were perceived as low-quality, temporary housing. They are not designed to be moved once they have been assembled on their foundation. Unlike mobile homes, modular homes are subject to the same building codes as traditional stick-built homes. Modern modular homes are built to higher standards, and this association persists.

Many people are unaware of the advancements in modular home construction and may not understand the differences between modular, manufactured, and site-built homes.

Early modular homes had a reputation for being poorly constructed with low-quality materials such as lower-grade lumber or plywood with fiberglass batts for insulation. While this is no longer the case, the stereotype persists.

Due to the perceived inferiority of modular homes, some buyers worry that they may have lower resale values typically 5 – 10% less compared to traditional site-built homes, and some banks even won’t mortgage a modular building.

Many modular homes are now indistinguishable from site-built homes and are built to the same or higher quality standards, offering a cost-effective and efficient alternative to traditional construction methods.

Are Modular Buildings Better Than Premade Houses?

Modular construction is a part of the construction modularization and prefabrication industry.

The first traces of modular construction date from the pre-industrialized eras in Europe in the 1600s – 1800s and primarily involved simple prefabrication methods of building components off-site, such as timber frames, and transporting them with horse carriages or ships for assembly on location from England across the Atlantic ocean. In 1837, carpenter John Manning constructed the first documented modular home for his son emigrating to Australia from Britain. During the Gold Rush in California, some workers ordered from multiple New York factories to build and ship homes in parts, allowing them to save time and focus on developing the mining towns.

In the 1900s, inspired by the efficiency of factory production lines, companies like Sears, Roebuck & Co invented mail orders for home kits with pre-cut and numbered components for easier assembly; by 1908, nearly 400 designs were available for purchase, and in the 1940s, they marked 75,000 sold units. Prefab Quonset huts (arc-shaped structures) made of corrugated steel were introduced during World War II for military housing and other uses. The period after WWII saw an increased adoption of modular construction methods aimed at addressing the need for affordable homes. This was when Ingvar Kamprad founded Ikea (July 1943), adopting the mail-order methods, which led later in 1956 to the introduction of the flat pack furniture, another method of modular construction.

In 1957 Dr. Patrick J. Hanratty intended PRONTO, on the basis of which Ivan Sutherland, MIT’s engineer, created SKETCHPAD, the first CAD-driven application with basic principles of producing computer technical drawings. By the 1970’s early 2D CAD programs such as CADAM, UNISURF, CATIA, ADAM, and others were used by architects and engineers to develop blueprints and sketches for modular construction; since that point, modular construction expanded to other building types like offices, schools, and medical facilities. 3D CAD was not widely used in the 1970s, and most design work was still done with pen and paper; CAD was mainly limited to producing 2D drawings similar to hand-drafted ones for conveyor belt productions. 3D CAD was primarily used by automotive and aerospace industries for high-value products.

Late 20th Century 3D CAD BIM software revolutionized design precision and allowed for better customization of modular units called Modularization. BIM facilitated better coordination between architects, engineers, and manufacturers, streamlining the modular construction process, leading to lighter-weight, high-strength materials like steel and engineered wood, and expanding possibilities for larger and more complex modular designs of precast concrete modules and steel.

21st Century saw factory production shift towards near-complete volumetric module prefabrication, including finishes, fixtures, and even appliances. This sped up the on-site assembly process significantly, by further 50% shortening the time needed for on-site development. Today modular buildings offers superior energy efficiency, waste reduction, and greater control over materials compared to traditional building methods. Modular projects range from affordable housing and temporary structures to high-end, architecturally stunning homes and commercial buildings.

From what materials modular buildings can be?

Modular buildings offer much flexibility in terms of materials, with core materials being wood, steel, and concrete. 

Core Structural Materials

  • Wood: Traditionally the most common for residential modular buildings. Wood framing is lightweight, easy to work with, and readily available.
  • Steel: Provides superior strength, durability, and resistance to pests and fire. This makes steel ideal for larger, multi-story structures or buildings in areas prone to extreme weather.
  • Concrete: Pre-cast concrete modules offer unmatched durability, fire resistance, and sound insulation. However, they are heavier and less flexible in design, making them best suited for large-scale or highly specialized applications.

Additional Construction Materials

  • Insulation: Like traditional homes, insulation options include fiberglass, spray foam, mineral wool, and rigid foam. The choice depends on the desired level of thermal performance and budget.
  • Interior finishes: Gyprock/drywall is standard for interior walls. Flooring materials can range from carpet and vinyl to hardwood and tile.
  • Exterior finishes (cladding): Modular homes offer exceptional variety. This includes vinyl siding, wood or composite siding, brick or stone veneer, metal panels, stucco, and others.

Modular homes vs manufactured homes?

The key difference between modular and manufactured homes is in their permanency. Modular homes are placed on a permanent foundation and cannot be moved after installation, while manufactured homes are often placed on a temporary foundation and can be relocated.

Can Modular homes turn to a farmhouse?

Modular homes provide the flexibility to adopt various architectural styles, including farmhouses. They can be customized with features such as wrap-around porches and gabled roofs to fit the aesthetic of a traditional farmhouse.

What the limits on Modular homes?

There are seven most prominent limitations of modular homes, with the main ones being – stigma and financing. Despite improvements in quality, some people may still view modular homes as inferior to traditional site-built homes, which can affect resale value, thus some lenders may be less familiar with modular homes, which can make securing financing more challenging compared to traditional homes.

Land and zoning are limitations of modular homes, and they must comply with local zoning regulations and building codes. Some areas may have restrictions on modular homes or require additional permits.

While modular homes offer some customization options, they may not be as flexible as site-built homes. Structural changes and unique design elements can be more challenging to incorporate and can lead to price increases.

Transport is another issue of the module housing. Since modules are built in sections and transported to the building site, the size of the modules is limited by transportation regulations, such as highway width and height restrictions, as well as the capacity of trucks and cranes used for delivery.

Why to buy a Modular House?

People buy modular homes because of affordability. Modular homes are typically 10-20% less expensive than site-built homes of comparable size and quality. For instance, a 1,800 square foot site-built home costing $300,000 might be built as a modular home for a price between $240,000 and $270,000.

The cost efficiency of modular homes is often attributed to the controlled factory environment, reduced material waste, and streamlined construction timelines. The average homeowner typically pays $100-$200 per square foot, or a standard 1,800-square-foot modular home may cost between $180,000 and $360,000. In the end homebuyers can get more house for their money.

Why Modular construction means less troubles?

Modules are designed with primarily utilitarian goals, to be simple and effective construction methods and not that luxurious. Material choices should reflect the intended use.

Construction projects face an alarmingly high delay rate, with 80% experiencing setbacks. The main causes include:

  • Weather-related Delays: Traditional construction is heavily impacted by rain, snow, etc.
  • Poor Planning: Unrealistic timelines and inadequate risk assessment lead to problems.
  • Scope Changes: Late-stage client requests for alterations cause rework and longer schedules.
  • Other Factors: Design issues, labor shortages, permit delays, and lack of resources further compound delays.

Modular construction offers a significant advantage in mitigating the common pool planning, scope changes and weather-related causes of delay:

Factory construction eliminates weather-related delays entirely. Work continues regardless of outside conditions, ensuring faster completion times. The factory setting allows for precision planning, minimizing unexpected hurdles that derail traditional projects.

While customization is possible, modular homes often rely on well-tested designs, reducing the need for on-the-fly changes that slow down site-built projects. The assembly-line nature of modular construction promotes efficient workflows and allows for better resource management.

Example: Consider a project with an estimated 6-month timeline. If a traditional site-built home experiences weather delays, poor planning issues, and a scope change, it could easily take 8 months or more. A comparable modular home, built concurrently in the factory, might be completed in the original 6-month timeframe.

Can modular homes be 2 stories?

Yes, modular homes can be designed to be multi-story structures, offering the same level of variety and functionality as traditional two-story homes. Modular homes can have 5 bedrooms or more, allowing for ample living space suitable for larger families or those desiring extra rooms. 

The width of a modular home is typically constrained by transportation limits, but most can be up to 16 to 18 feet wide per module. Multiple modules can be combined to create larger widths.

What are typical modular homes plans?

The layout for modular homes vary depending on size, location and budget. Externally and internally the style can include ranch-style, two-story cape cod or contemporary models,  the options are limitless with diverse layouts to meet specific homeowner needs.

For example the below single-story modular home offers a simple, efficient layout with a combined living and dining area, two bedrooms, and one full bathroom. The optional sun room adds flexibility to expand the living space if desired, making the property ideal for retirement or vacation house.

The main entry leads into the living room, which measures approximately 15′ x 13′-4″. Adjacent to the living room is a dining room with dimensions of 10′-10″ x 10′-6″.

The kitchen is open to the dining area, creating an open-concept living space. There is an optional sun room that can be added to the dining area, providing additional living space and natural light.

To the right of the living room are two bedrooms. Bedroom #1 (Master bedroom with en-suite) is situated at the rear parts of the home far from the main living area and measures approximately 12′-10″ x 10′-0″. Bedroom #2 is located closer to the living area behind Bedroom one’s bathroom and has dimensions of 11′-5″ x 13′-2″, making it ideal for a kids room.

A full bathroom is positioned between the two bedrooms, conveniently accessible from both bedroom #2 and the other parts of the property.

A small utility closet or pantry is located next to the bathroom and between the kitchen, providing space for a washer, dryer, other mechanical equipment in support of the kitchen area.

How long it takes to design a modular house?

In total, the design process for a modular home can take anywhere from 6 to 12 weeks, depending on the factors as size, complexity, features, materials and location of the building. This timeframe can be shorter or longer based on the project’s specific requirements and the client’s decision-making process.

Here’s a general breakdown of the design process and the estimated time for each stage:

  1. Initial consultation and concept development (1-2 weeks): The client meets with the design team to discuss their requirements, preferences, and budget. The team then creates a concept design based on these inputs.
  2. Design development and revisions (2-4 weeks): The design team refines the concept and creates detailed floor plans, elevations, and 3D renderings. The client reviews these and provides feedback, leading to further revisions.
  3. Permit and construction documentation (2-4 weeks): Once the design is finalized, the team prepares the necessary documentation for building permits and construction, including detailed specifications and engineering calculations.
  4. Final review and approval (1-2 weeks): The client reviews the final design and documentation, and upon approval, the project moves to the fabrication and construction phase.

It’s important to note that the design phase is just one part of the overall process. The fabrication and on-site construction of the modular home will also take additional time, which can vary based on the project’s scale and complexity.

how much does it cost to design a modular home?

On average, you can expect to pay anywhere from a few thousand to around $20,000 or more for the design of a modular home, depending on personal preferences. It’s essential to discuss design fees upfront with your chosen designer or modular home company to get a more accurate estimate for your specific project.

Larger homes with intricate designs will naturally cost more to design than smaller, simpler ones. The more customization you want (unique layouts, specific features), the higher the design fees will be.

Professional fees can vary based on experience, reputation, and location. Some modular home manufacturers include basic design.

If your land has slopes, unusual soil conditions, or other challenges, those will need to be factored into the design, adding to the cost. In addition to the design drawings, you’ll need engineering plans and may need to budget for permit fees.

Cost Ranges

  • Basic Designs: For a simple modular home using a standard floor plan with minimal customization, design costs might range from $2,000 – $5,000.
  • Moderate Customization: If you are modifying existing plans or have some unique features, expect costs around $5,000 – $10,000.
  • Highly Customized Designs: For complex, fully bespoke modular homes, design costs could range from $10,000 upwards.

Design costs are just one part of the overall cost of a modular home. Don’t forget to factor in manufacturing, transportation, site preparation, and installation expenses.

Work with Experienced Modular Designers. Professionals specializing in modular construction understand the nuances and can design efficiently within the constraints. Many modular home manufacturers offer design packages or in-house design services, which can sometimes be more cost-effective.

Be upfront with your designer about your budget and desired level of customization, so your expectations are aligned.

What are unique selling points in a modular house?

Choose a standard or smaller floor plan over a custom design.

Opting for a smaller home with a more efficient layout can significantly reduce construction and materials costs. Deviating from standard options and extensive customization can increase design costs by $10 to $150 per square foot.

Keep the design simple and efficient.

Maximizing the length of the modules to the maximum size (e.g. 64 feet) provides more space at a lower cost per square foot. A boxy, simple design with fewer custom features will cost less than a complex layout with many upgrades.

Avoid expensive factory-installed options and finishes.

Selecting factory options like hardwood flooring, decorative trim, and high-end finishes will significantly increase costs. These can often be added more affordably after the home is built. Stick with the standard, mid-grade finishes offered by the manufacturer, which only nominally increase the base price

Minimize complex roof lines and exterior details.

Complex roof designs and intricate exterior details can add to the cost of construction. Opting for a simpler roof line and fewer exterior embellishments can help save money.

Consider a single-story design.

Single-story homes are often less expensive to build than multi-story homes due to simpler construction and the elimination of stairs.

Focus on energy efficiency.

While energy-efficient upgrades cost more upfront, features like extra insulation, energy-efficient windows, appliances, solar panels, or heat pumps will reduce your long-term utility costs.

Work with a reputable modular home company.

Choose a manufacturer with a track record of quality construction and cost-effective designs. They may offer valuable guidance on how to achieve your design goals within your budget.

Avoid making changes during construction.

Making changes to your design after construction has begun can lead to costly change orders. Finalize your design before construction starts to avoid these additional expenses.

Conduct thorough site research.

Document every step of the construction and plan visits to the factory. Understanding your building site’s characteristics, such as slope, soil conditions, and zoning requirements, can help you avoid costly surprises and design revisions down the road.

Red flags in modular homes?

Modular homes offer an attractive alternative to traditional stick-built homes, promising faster construction times and potentially lower costs. Just like any major real estate purchase, there are potential pitfalls to avoid.

Here’s a breakdown of red flags to watch out for in modular constructed buildings, categorized by scope:


Builder Red Flags

  • Lack of experience: Look for a builder with a proven track record in modular construction. A new company or one with frequent leadership changes might lack the expertise to handle complexities.
  • Financial instability: Be wary of builders with a history of delayed payments to suppliers or a reluctance to invest in modern equipment. This could indicate financial trouble, leading to project delays or use of lower-quality materials.
  • Unrealistic promises: If a builder offers prices significantly lower than competitors or guarantees an implausibly fast turnaround, it’s a cause for concern.

Material and Construction Issues

  • Substandard materials: Modular homes are built to strict codes, but some builders might use lower-quality materials to cut costs. Be sure the builder uses materials that meet relevant building codes and inquire about the specific brands and types of materials used for framing, insulation, and finishes.
  • Poor quality control: Factory-built environments offer some advantages in quality control, but inconsistencies can still occur. Look for a builder with a rigorous quality control process and ask if you can visit the factory to see it firsthand.
  • Improper site work: The foundation and connection of the modules on-site are crucial for the home’s long-term stability. Ensure the builder has a qualified crew for foundation preparation, and inquire about the methods used to join the modules together.

Unique and Rare Defects

  • Improper transportation damage: While uncommon, modules can sustain damage during transport. A thorough inspection upon arrival at the building site is essential to identify any potential issues like cracked walls, misaligned sections, or damaged roofing.
  • Moisture problems: Modular homes, like any structure, can be susceptible to moisture issues if not properly sealed. Look for signs of water damage, mold, or condensation during inspections. Pay attention to flashing details around windows, doors, and roof penetrations.
  • Hidden defects: As with any home, there’s always a chance of hidden defects. A thorough inspection by a qualified professional is crucial to uncover any potential problems before they become major issues.

Modular house vs converted Barn

Both barns and modular buildings often utilize metal as a primary construction material, making them fall under the broad category of “metal buildings.”

Modular homes are specifically designed and constructed as residential dwellings from the outset, where barns are originally designed for agricultural purposes and later converted into living spaces.

Offer a wide range of customizable designs, floor plans, and finishes to suit individual preferences but mostly have identical architectural patterns, while converted barns offer a distinctive, rustic charm and historical character that appeals to some homebuyers.

Modulars are built with energy efficiency in mind, incorporating features like high-quality insulation and efficient HVAC systems, while retrofitting a barn to be energy-efficient can be more challenging and expensive compared to purpose-built modular homes.

Converting a barn into a home may require significant renovations to meet residential building codes, such as installing proper insulation, HVAC systems, and plumbing, where modular constructed property is designed to meet current building codes and regulations for residential homes.

Financing on modular is easier, as banks and lenders are familiar with modular home construction, where securing mortgage for a barn conversion may be more difficult, as it is considered a non-traditional property.

The resale value of a converted barn may be more dependent on its unique character and the demand for such properties in the local market, while well-constructed modular homes can appreciate in value, similar to traditional site-built homes.

Converted barns may require more specialized maintenance due to their unique construction and age, while modular buildings require regular home maintenance, such as HVAC servicing, roof inspections, and exterior upkeep.

Can you move modular building?

Yes, modular buildings can be designed to be movable, although not all are built with this purpose in mind. Relocatable modular buildings offer the flexibility to be transported to different sites as needed, but the process requires careful planning, engineering, and adherence to local regulations and likely will increase your building’s costs by at least 15% of the total costs.

Relocating a modular home is a significant undertaking that can cost anywhere from $5,000 on the low end for a small transport-only move, up to $30,000 or more for a full-service move of a large triple-wide home

Relocatable modular buildings: Some modular buildings, often referred to as “relocatable” or “portable” buildings, are specifically designed to be moved from one location to another. These buildings are often used for temporary or semi-permanent purposes, such as classrooms, offices, or construction site accommodations.

Transportation methods: Modular buildings can be transported using flatbed trucks, trailers, or even cranes, depending on their size and weight. The individual modules are typically designed to withstand the stresses of transportation.

Structural considerations: Movable modular buildings are engineered with transportation in mind. They may have additional structural reinforcements, such as steel frames or cross-bracing, to ensure stability during transport and relocation.

Site preparation: Before relocating a modular building, the new site must be prepared with the necessary foundation, utilities, and permits. The ease of relocation can depend on the specific site requirements and local regulations.

Permanent modular buildings: Some modular buildings are designed and constructed to be permanent structures, similar to site-built buildings. While it may be possible to move these buildings, it can be more challenging and costly, as they are not specifically designed for relocation.

  • Cost considerations: Moving a modular building can be expensive, as it requires specialized equipment, labor, and transportation. The cost of relocation should be weighed against the cost of constructing a new building at the desired location.

Transport-only move (attaching home to towing vehicle, moving, and unhooking at new location):

Single-wide: $700 – $1,000 for up to 60 miles
