Additions That Work With the Slope

On a sloped lot, an addition can go out, up or down the hill. Each direction asks something different of the foundation, and we price them side by side.

Tell us about the lot and the job

A builder reads it and calls or emails you back. Nothing is booked until you agree to it. How we use your details.

To send, add your first name and a phone number or an email.

Out, up or down

Building out may mean new footings on the grade. Building up means the existing walls and foundation must carry a new floor. Building down the slope can add a lower level with a retaining wall at its back. We compare them before you choose.

Tying into the existing house

The new structure has to join the old one cleanly: matched floor heights, a roof that sheds water across the joint and a foundation connection the engineer approves.

Permits and setbacks

Additions need a permit, and hillside parcels can add grading, height or fire rules on top. We check the parcel before drawings start.

Room Additions: questions

Need more room?

Tell us how the house sits on the lot and how much space you want. We will look at which direction makes sense.
