More space, built to look like it was always there
A good addition is one you cannot spot from the street. The stucco matches, the roof lines up and the floors run straight through from the old house to the new room. Mejia Construction builds home additions in Cathedral City and across the Coachella Valley, and we plan every tie-in before the first trench is dug.
Additions we build
- Room additions and bump-outs that add a bedroom, office or bigger living area.
- Primary suite additions with a bedroom, walk-in closet and bathroom.
- Family room expansions that open toward the backyard or pool.
- Attached units designed for independent living are covered on our ADU page.
How a home addition comes together
- Feasibility. We look at setbacks, lot coverage, the existing structure and where the addition connects.
- Plans and permits. Drawings are prepared and submitted for plan review, including the energy calculations California requires.
- Foundation. Footings and slab poured to plan; our concrete work starts here.
- Framing and roof. Walls and roof framed and tied into the existing house, then roofed and sealed.
- Rough-in and insulation. Plumbing, electrical and HVAC run, then insulation inspected.
- Finishes. Stucco outside; drywall, flooring and paint inside.
- Final inspection and walkthrough. The addition is signed off and cleaned.
Signs an addition makes sense
- You love the neighborhood but the house no longer fits your family.
- Moving would cost more than building the room you need.
- You have yard space on a side or the rear that is not doing much.
- You want a primary suite that the current floor plan cannot give you.
Building additions in desert conditions
Most homes in the valley are slab-on-grade with stucco walls, so an addition starts with new footings and a slab that ties into the existing foundation. Summer heat affects the schedule: concrete pours happen early in the day, and exterior work is planned around the hottest hours. Inside, the biggest comfort decision is cooling. A room that bakes in July is not the space you paid for, so insulation, window placement and air conditioning get planned with the layout, not after it.
Riverside County and each city set their own rules, so we confirm requirements for your address before plans are drawn. That way the design you fall in love with is one the city can approve.
