Project perspective
Small spaces feel generous when every inch has more than one job.
Built-in seating, concealed storage, clear circulation, and a strong connection to the garden can make a compact footprint feel open and useful.

Before we talk
What affects early ADU planning?
Property layout, intended use, unit type, access, utilities, and local requirements all influence the right path.
Can you help us think through scope and selections?
Yes. The goal of the early conversation is to connect practical needs, visual preferences, and project dependencies before the work is organized.
What should we prepare for the first conversation?
Share the project address, photos of the current conditions, the result you want, timing considerations, and any inspiration or existing plans you have. It is fine if some details are still undecided.
What affects project timing?
Scope, design and selection decisions, existing conditions, permit review where required, material availability, and coordination with connected work can all affect the schedule. Timing is discussed for the specific property and project.
