Additions & Casitas

Room additions, detached casitas, garage conversions.

Permitted engineering, clean tie-ins to existing structure, and an exterior finish that looks like it was always there.

Additions are the project most likely to look added — and that’s usually because somebody cut corners on the tie-in. The new roof line doesn’t carry. The stucco color is two shades off.

We build additions to match. New footings tied to existing per engineering. Roof framing scarfed clean. Stucco color matched on a slab sample, not eyeballed. Window package selected to match the house.

Casitas — detached or attached — are a fast-growing scope in Phoenix. Multigenerational, rental-eligible, or just a real guest suite. We permit them as ADUs where the city allows it, with full kitchens or kitchenettes, full baths, and finishes that match the main house.

Scope types

What we build under this category.

Room additions

Bedroom, primary suite, family room, office. Attached to the existing footprint with matching envelope.

Detached casitas

400–800 sq ft permitted structures. Full bath, kitchenette or full kitchen. Often ADU-eligible.

Garage conversions

Permitted conversion to conditioned space. Mini-split, finished walls and floor, full bath if plumbing reaches.

Second-story additions

Where the lot, code, and existing structure all allow. Engineering-heavy. We’ll tell you honestly if it pencils.

Bump-outs

Kitchen or primary suite expansion under a continuation of the existing roof line. Faster permit, cleaner finish.

Workshops & studios

Insulated, conditioned outbuildings with electrical sub-panels and finish quality matching the main house.

Budget bands

What additions actually cost.
