Site-built Homes vs. Factory-built Homes | Ultimate Comparison

|Apr 21, 2024

You're diving into the world of homebuying, and you've stumbled upon a crucial decision point. Should you go for an on-site-built home or opt for a factory-built one? It's a big question with even bigger implications for your future comfort, convenience, and budget.

Don't worry; we've got your back. In this ultimate comparison, we'll break down everything you need to know about custom-built homes and factory-built alternatives. By the end of the article, you'll be able to make the best decision for your dream property.

What Are Factory-built Homes?

First off, let's clear up any confusion about the terminology. When we mention factory-built homes, we refer to those made entirely or primarily in a factory setting. These include modular homes, manufactured ADUs, and pre-built container homes.

A prefab ADU is like the IKEA furniture of the housing world. It is ready to assemble and often customizable to your heart's content.

Whether you're eyeing a sleek studio office or an eco-friendly home office shed, the factory-built route offers a world of possibilities.

Before you start picturing rows of cookie-cutter houses rolling off an assembly line, let's break down the different types of factory-built homes.

Modular Homes

These bad boys are almost like LEGO sets for grown-ups. You get individual modules constructed off-site and then assembled on your chosen plot of land.

Think of it as building blocks for your dream home. You can mix and match different modules to create a layout that's uniquely yours.

Manufactured Homes

On the other hand, these gems are also built in a factory setting. However, they are typically made on a steel chassis, making them more mobile than traditional stick-built homes.

Don't let the term "manufactured" fool you, though. Homes built in a factory boast the same level of comfort and quality as their site-built counterparts. Still, they have the bonus of quicker construction times and lower costs.

What Are Site-built Homes?

Think of on-site-built homes as the OGs of homeownership. You can build them right on your chosen plot of land, from the ground up, with love and elbow grease.

Unlike factory-built homes, which are made in a controlled environment and then transported to their destination, site-built homes take shape right before your eyes, brick by brick (or stud by stud).

However, site-built homes are anything but old-fashioned. In fact, they offer unparalleled flexibility and customization, allowing you to create a home that's yours, inside and out.

From the floor plan's layout to the cabinets' finishing, every detail is yours to decide, ensuring your home pottery studio or work shed reflects your personality and lifestyle.

Plus, there's something magical about watching your house take shape from the ground up. You can feel proud knowing every nail hammered and wall painted is a step closer to turning your dream home into reality.

Common Differences Between Factory-built Homes and On-site Structures

Imagine a backyard studio shed being built indoors, in a factory setting, away from the unpredictable weather.

That's the beauty of factory-built homes. Manufacturers like Autonomous make such units in sections or modules. Afterward, it transports the structure to your chosen location for assembly.

Speedy Construction

Since these homes are usually built in a controlled environment, there are fewer delays due to weather or other external factors. You will likely move in quicker than with a traditional site-built home.

Quality Control

Factory-built homes undergo stringent quality checks at every stage of construction. This means you're getting a unit built to high standards, with fewer chances of errors or defects.

Eco-friendly Options

Many pre-built container homes have sustainability in mind. They often use energy-efficient materials and construction techniques, making them a greener choice for the environment-conscious buyer.

Cost Savings

Because of the streamlined process and bulk purchase of materials, custom-built homes can sometimes be more cost effective than traditional properties.

Next, we have the traditional site-built home. Here, skilled craftsmen work their magic right on your plot of land. Such homes are made entirely at the location where they will stand.


With site-built homes, you have more flexibility in design and layout. You can work closely with architects and builders to create a home that fits your vision and needs.


Building on-site allows for adjustments to be made quickly during the construction process. If you want to add a window or change the layout midway, it's usually doable.


Long-term Value

While initial costs might be higher than factory-built homes, site-built homes often appreciate more over time. This could give you a better return on your investment.

Factory-built or Site-built Homes: Which Should You Choose?

On the one hand, we have factory-built homes. You can build such units faster, stronger, and often more affordable than their site-built counterparts.

Factory-built homes offer unparalleled customization options, with everything from modular designs to pre-built container homes available to suit your style and budget.

Thus, a factory-built home might be the way to go if you're looking for speed, affordability, and customization.

On the other hand, we have site-built homes – the tried-and-true method for ages. They take longer to build and come with a higher price tag than factory-built alternatives. However, on-site-built homes offer unmatched flexibility and customization, as mentioned above.

As a result, if you crave the flexibility and charm of a home built from scratch, then a site-built home could be your perfect match.

What Are the Cons of Factory-built Homes?

While factory-built homes offer some customization, they usually have limitations compared to site-built homes. You might have fewer options when choosing specific design elements, layouts, or finishes.

Transportation Challenges

One of the biggest hurdles with factory-built homes is transporting the completed structure from the factory to your desired location. This process can be logistically complex and incur additional costs, mainly if your site is far from the factory.

Perception and Resale Value

Despite advancements in design and construction, there is still a stigma surrounding factory-built homes. Some potential buyers may perceive them as lower quality or less desirable than site-built homes. This could affect their resale value in specific markets.

Potential for Delays

Factory construction offers the advantage of controlled environments and streamlined processes. Still, you can expect delays due to material shortages, equipment malfunctions, or production bottlenecks.

Limited Location Options

Custom-built homes need access to transportation routes to accommodate oversized loads. This could limit your options for where to place your home, especially in remote or rural areas.

What Are the Cons of On-site Built Homes?

On the other hand, we have on-site-built homes. These structures have a higher price tag compared to factory-built options. 

The labor-intensive nature of on-site construction and factors like fluctuating material costs and skilled labor shortages can drive up overall construction costs.

Longer Construction Timelines

Unlike factory-built homes assembled in a strict setting, on-site-built homes are subject to weather delays, permitting issues, and other challenges that extend construction timelines.

Weather Dependency

Bad weather can wreak havoc on site-built construction projects, causing delays, damage to materials, and increased labor costs. Rain, snow, extreme temperatures – you name it. Mother Nature can throw it all at your construction timeline.

Design Limitations

While site-built homes offer many customization options, there can also be limitations in terms of design flexibility. Certain architectural styles or features may be more challenging or costly to implement in a site-built setting than factory-built alternatives.

Potential for Construction Errors

With on-site construction, there's always the risk of human error, from misaligned walls to faulty wiring. Reputable builders strive for quality craftsmanship. Still, mistakes can happen, leading to costly repairs or renovations down the line.

Overall, both factory-built and site-built homes have their set of challenges and considerations to weigh. It ultimately comes down to your priorities, budget, and lifestyle preferences when deciding between them.

What Are the Cons of On-site Built Homes?

The Cost of Making Factory-built Homes

Generally, a studio shed per square foot price can range between $30 to $150+. One aspect that adds to the cost of factory-built homes is transportation. Once the manufacturer has made all the modules or sections, they need to transport them to the assembly location.

Transportation expenses can vary depending on the distance and the size of the units. You also need to consider the cost of equipment rental for installation.

On the other hand, most factory-built homes offer certain standard designs and layouts. Many manufacturers provide customization and upgrade options.

These can include features like appliances, flooring, countertops, and more. However, each customization typically adds to the initial price tag, so buyers should be mindful of their budget when selecting these options.

The Cost of Making Site-built Homes

Unlike factory-built homes, on-site structures cost $125-$250 per square foot. Before the construction starts, the site must also undergo preparation, including land clearing, grading, excavation, and utility installation.

The cost of site preparation varies depending on its condition, accessibility, and the extent of work needed.

On-site-built homes are also subject to local building codes and regulations, adding to the initial price tag.

Zoning regulations and proximity to amenities can influence land prices. On top of that, site characteristics such as topography, soil conditions, and environmental considerations may impact development costs.

At the same time, setting aside contingency funds can mitigate the risk of cost overruns due to unexpected challenges, delays, or plan changes.
