If you’re planning a backyard home or a few guest cabins, the design is only part of the decision. You also want to know how long construction will take, how much work will happen on your property, and where your money will go.
Modular construction can help with all three. By completing more of the work in a factory, it leaves less to be done on-site. Here’s how that changes the building process—and how MAVE’s three options fit different projects.
A head start on construction
With a traditional build, most of the house takes shape on your property. The foundation goes in, the frame goes up, and crews work their way through plumbing, electrical, insulation, and finishes. Many of those steps depend on the previous one being finished.
With modular construction, the factory can work on the home while a local crew prepares the site and foundation, once the necessary approvals are in place. Two parts of the project move forward at the same time.
That overlap can make a real difference. McKinsey’s 2019 research found that modular projects had shortened schedules by 20%–50% compared with traditional construction.[1] Your own timeline will depend on permits, production availability, delivery, and site work, but doing more in parallel creates room to save time.
Indoor production helps too. Rain may slow work in your backyard while the factory continues building.
Less work on-site, fewer labor hours to pay for
Think about what happens on a building site each day. Materials are unloaded and moved around. Pieces are measured, cut, and fitted. Crews set up their tools, pack them away, and return for the next stage.
In a factory, equipment and materials can be arranged around the work. Teams can repeat familiar details, and prepared components arrive with some of the measuring, cutting, and assembly already done.
For you, that can mean fewer hours of local construction labor and less waiting between trades. A 2025 study commissioned by the Home Builders Institute found that skilled labor shortages added about two months to construction schedules on average.[2] Moving some work into a factory can reduce reliance on local crew availability, although factory schedules still matter.
The amount you save depends on how much work is completed before delivery and what that work would cost locally.
Savings beyond the labor bill
A shorter build may also mean fewer weeks of equipment rental, site management, and construction-loan interest. If you’re building a rental ADU or guest cabin, finishing earlier may let you welcome tenants or guests sooner, after the required approvals.
There is potential for substantial savings, especially when a project repeats the same design across several homes. McKinsey identified construction-cost savings of around 20% or more as achievable under favorable conditions, including scale and an optimized production system.[1]
For an individual project, compare the full installed cost: the home, foundation, transportation, installation, utilities, design, and permits. That gives you a much more useful picture than comparing a factory price with a contractor’s complete building quote.
A more controlled build—and a quieter property
Factory construction makes it easier to protect materials from weather and check work at each stage. Preparing components together can also help use materials efficiently and reduce waste.[3]
Quality still comes down to good design, good materials, and careful work, including the final installation.
There’s another benefit you may notice more directly: less construction activity on your property. If you live beside the future ADU, or operate a resort while adding cabins, reducing the time crews spend on-site can make the process easier to live with.
The catch: delivery needs a plan
A largely finished home is a big thing to move. Trucks need a suitable route, and installation may require a crane and enough space to work.
A narrow driveway or difficult site access can add costs that offset some of the labor savings. Checking access early helps you choose the right approach. Smaller prefabricated pieces may be a better fit for some properties.
Three ways to build with MAVE
MAVE offers three options based on how much of the home is completed before it reaches your property.
Fully Modular Homes
Built in the factory. Delivered largely finished.
The home arrives as a complete unit or finished sections. Most of the building work—including interior finishes and the systems included in your package—is completed at the factory.
Your local team handles the foundation, placement, utility connections, and any remaining installation work.
This option offers the greatest opportunity to reduce on-site construction, provided the property has suitable delivery and installation access.
Semi-Modular Homes
Prepared in the factory. Assembled on your property.
Parts of the home are built ahead of time, then delivered for assembly. Depending on your project, these might include wall panels, floor sections, roof components, or other prepared pieces.
Think of it as a carefully designed kit: the pieces are made to fit together, so the crew has less fabrication to do on-site. Remaining systems and finishes are completed locally, with the exact split agreed for your project.
This approach can save site labor while keeping the pieces smaller and easier to transport than a fully assembled home.
Material Kits
A coordinated material package. Built on-site by local crews.
MAVE supplies the materials for your project, and your contractor builds the home using conventional on-site methods.
More of the labor happens on your property. The benefit is having the design and material selections coordinated in advance, giving your local team a clear starting point.
This can be a good fit when site conditions or your contractor’s preferred approach favor a traditional build.
Which option fits your project?
Start with the property: can a completed home reach the site, what does local labor cost, and how much construction do you want happening there?
Project size matters too. One backyard home and a group of matching guest cabins may benefit from different approaches.
