Why design-build

One team coordinating the entire project

We do more than build what someone else drew. We help you understand your options, then carry the project from first conversation through construction.

01

One Team From Start to Finish

The people who design your project are the same people who permit, price and build it.

02

Feasibility + Planning

We look at the lot, zoning, utilities and access first, so decisions start from what is actually possible.

03

Design

Plans developed around your property, your household and your budget — not a fixed package.

04

Permitting

Applications, review responses and municipal coordination handled for you.

05

Construction

Trades, inspections and communication managed through completion.

06

Real Estate Perspective

Licensed real estate services when buying or selling is part of the plan.

Why homeowners call us

Real situations, not sales pitches

Most projects start with a change in the household, not a floor plan. Our job is to help you understand what your property can do about it.

Mom or Dad needs to live closer
An adult child needs independent living space
The family needs more room but doesn't want to move
You want a custom home built around how you actually live
The existing home no longer works for the family
A property has potential nobody has evaluated yet

Aging Parents

Independence and privacy on the same property, with family close enough to help.

Adult Children

A stable first place to live while saving for what comes next.

Multigenerational Living

Three generations on one property without sharing a kitchen.

Guest Space

Room for visiting family without giving up a bedroom in the main house.

Full cost transparency

Know where every dollar of your project is going

Because we handle both design and build, your budget shapes the design from the start — not after the plans are drawn.

01

Early Stage

Preliminary Budget Range

A wide planning range based on size, ADU type, a first read of site conditions and a general finish direction. Enough to decide whether to keep going.

02

Design & Scope Development

Budget Refinement

As plans, structure, utilities and selections take shape, the range narrows and the assumptions behind it become explicit.

03

Completed Plans + Defined Scope

Detailed, Line-by-Line Final Pricing

Once drawings are complete and scope is defined, pricing is presented line by line — what is included, what is allowance, and what is excluded.

We work with you throughout the design process. Since design and construction sit under one roof, we can ensure we are designing something that meets your needs, your property and your budget.

Once the plans are completed and you have made all of your decisions on finishes and design selections, we present a final construction contract — fully detailed, line-by-line, with the full scope of work.

If at that point we need to reduce the scope of work or make adjustments to finishes, allowances or materials, we will work with you to value engineer the project to meet your goals.
