Choose your build path
Multiple ways to build an ADU — one accountable team
Some projects are best suited to a modular home. Others make more sense as an on-site custom build. We help you choose the right path for your lot, budget, and timeline before you go too far into design.

What this page helps with
- Understand the main ways to build
- Compare speed, flexibility, and approval paths
- Choose the right path before design starts
Start here
Start with clarity, not guesswork.
The first step is not choosing a design. It is confirming what your property can realistically support. We review zoning, access, site constraints, and the likely permit path so you can make a smarter decision early.
- Confirm what is likely allowed
- Flag common constraints early
- Outline the simplest path forward

Build paths
Choose your build path
We are not tied to one system or one manufacturer. That means we can recommend the build path that best fits your property instead of forcing your property into one way of building.
Modular / prefab builds
Fastest + most predictable
Built off-site in a controlled environment and delivered mostly complete, modular homes usually offer the most predictable path and the shortest on-site timeline. They can also be custom-designed, finished to a much higher standard than many people expect, and built for strong energy performance when that matters.
Best for: Homeowners who want predictable pricing, faster completion, and less disruption on site.
Panelized builds
Custom design + faster build
Panelized construction gives you more flexibility than a standard prefab model while still capturing some of the speed and efficiency of off-site construction.
Best for: Homeowners who want a custom home with more design flexibility, while still benefiting from a more efficient build process.
Full custom build
Highest flexibility
When the lot is unusual, the design goals are more specific, or a standard product is not the right fit, a full custom build gives the most flexibility.
Best for: Homeowners who want the most flexibility in layout, appearance, and overall design approach.
Local experience
Over 20 years building in the Sea-to-Sky.
With over 20 years of construction experience in the Sea-to-Sky, we are very familiar with local rules, approvals, site conditions, and trusted trade partners. That local experience matters because even the best product is only as good as the team handling the local path.
- Feasibility and lot review
- Permit coordination
- Site prep and foundation
- Delivery, crane, and install planning
- Utility connections, inspections, and handover
Partners and design paths
Partners and design paths we work with
We work with several modular and prefabricated partners so we can match the project to the property.
Good Way Homes
Custom modular homes and ADUs with strong energy performance.
Need help choosing?
We can help narrow down the right path before you go too far into design.
Custom Design
Partner with recognized architects and designers to create an ADU, carriage house, or small home that fits your property, goals, and budget. This path is best when a standard model is not the right fit and you want more freedom in layout, look, and overall design approach.

ADU Cost Guide
Use this when you want a clearer sense of cost drivers, realistic price ranges, and what tends to move a project budget up or down.
Our process
A clear path from lot assessment to install
Once the right build path is clear, we move into a straightforward process designed to reduce surprises and keep the project moving.
Free lot assessment
We start by reviewing what your property may be able to support and what constraints are likely to shape the project.
Site visit + direction
Once the project looks viable, we visit the site, review access and placement, and narrow down the best path.
Design + pre-construction planning
This is where we confirm scope, pricing direction, engineering needs, and the local permit path.
Permits + site prep
We coordinate the local side of the project so the site is ready when fabrication or construction moves ahead.
Build + install
Whether modular, panelized, or custom, we coordinate the build and carry the project through to completion.
