Home Addition and Remodel Plans in Palm Springs and the Coachella Valley

Black Diamond draws home addition plans and remodel plans for homeowners in Palm Springs, Palm Desert, Indio, and across the Coachella Valley. Every project starts with an on-site field measure, so the new space ties cleanly into your existing home and moves through plan check to an issued permit.

Home Remodel Plans That Add Space Without Moving

An addition or renovation is the right fit when your lot has room to grow and you want new features in the home you already own. A new bedroom, a home office, a larger kitchen, or a second story can complement your existing home and add to its value.

We've helped homeowners in Bermuda Dunes, La Quinta, and across the Coachella Valley plan expansions that suit their lot, respect the existing structure, and look as though they were always part of the house.

Why Hire a Professional for Your Home Addition

A successful addition builds on what you already have. New structure, rooflines, and utilities all tie into the existing house, so the plans need to account for how your home stands today and how the new space connects to it.

Black Diamond brings construction knowledge to every remodel set. We field measure your home before design begins, so the drawings match real conditions and your contractor builds from accurate dimensions. Demolition plans, structural coordination, and updated Title 24 documentation arrive in one set, and we answer plan check comments directly with the city until your permit is issued.

Additions and Remodels We Design

Room Additions

Bedrooms, home offices, primary suites, and sunrooms added at ground level. Our room addition plans match your home's existing architecture and cover the structural tie-in and energy compliance in the same set.

Second Story Additions

Building up adds square footage while keeping your yard and setbacks intact. Our second story addition plans address the added load on the existing foundation and framing, along with stairs, egress, and the new roofline.

Whole Home Renovations

Full-house remodels, including kitchen remodel plans and bathroom remodel plans, with demolition, new layouts, and any structural or utility relocation drawn together. Updated Title 24 documentation is included so the renovation permits as one project.

3 Steps to Approved Remodel and Addition Plans

02

Design the new layout

Demolition plans, the new floor plan and elevations, structural coordination, and updated Title 24 documentation are produced in one set.

03

Submit and manage plan check

We submit to the building department and revise through plan check until your permit is issued.
