Home Addition Henderson & Casita Builder — Design-Build for Henderson Homeowners
A home addition Henderson homeowners pursue is often driven by the same realization: the neighborhood is right, the home’s bones are solid, but the floor plan no longer fits how the household actually lives. Whether the goal is a detached casita for aging parents, a guest house for visiting family, a home office that functions as a real workspace, or a second-story build that doubles the home’s livable area — the project demands a team that can design, permit, and build the addition as one coordinated effort.
Kingdom & Co. operates a Henderson office on Warm Springs Road and has completed addition and remodel projects across MacDonald Highlands, Green Valley Ranch, Lake Las Vegas, and surrounding communities. Every home addition Henderson projects require moves through the City of Henderson Building Department — a separate jurisdiction from Las Vegas — and our team manages that process from application through final inspection.
Why Kingdom & Co. for Your Home Addition Henderson Homeowners Rely On
Henderson’s residential landscape ranges from hillside custom estates in MacDonald Highlands to contemporary production homes in Inspirada and Cadence. That range means no two addition projects start from the same architectural baseline. Kingdom & Co.’s design-build model pairs architects and builders from the first meeting — so the addition is designed to be buildable, not just renderable, and the construction team understands the design intent before breaking ground.
Our credentials back that approach: 2x NARI Remodeler of the Year regional winner, featured across eight episodes of HGTV’s Property Brothers, and listed in the Architectural Digest AD PRO Directory three consecutive years. We are members of the Southern Nevada Home Builders Association and the National Association of the Remodeling Industry.

Types of Home Additions We Build Across Henderson
Every home addition Henderson residents consider begins with a site evaluation — assessing the existing structure, the lot’s buildable envelope, and any HOA or zoning constraints that will shape the design. Kingdom & Co. designs and builds:
- Detached casitas — standalone guest houses with private entrances, bedrooms, bathrooms, and optional kitchens. Common on the larger lots found in MacDonald Highlands, Anthem, and Seven Hills where setbacks allow freestanding construction.
- Room additions — attached expansions that add bedrooms, primary suites, home offices, or living areas to the existing footprint. A frequent solution for homeowners in Green Valley Ranch and Cadence who need more space without relocating.
- Second-story additions — adding a partial or full upper level to single-story homes. Henderson’s newer master-planned communities include many single-story floor plans where vertical expansion is the most practical path to additional square footage.
- Garage conversions — converting underused garage bays into livable space, including studios, home gyms, or accessory dwelling units (ADUs).
- Outdoor living structures — covered pavilions, pool houses, and outdoor kitchens that extend livable area into Henderson’s year-round outdoor climate.
Each addition is designed to integrate with the existing home’s architecture — matching rooflines, materials, and proportions so the new construction reads as original, not bolted on.
Henderson Permitting and HOA Approval for Additions
Unlike most of the Las Vegas Valley, Henderson operates its own independent building department. All casitas, room additions, and construction that adds square footage require permits issued directly through the City of Henderson. The permitting process covers structural, electrical, plumbing, and mechanical work — and Henderson’s inspection timelines and requirements differ from those in the City of Las Vegas or Clark County.
Guard-gated and master-planned communities in Henderson add a second layer of review. MacDonald Highlands and Anthem Country Club maintain strict architectural review committees with detailed standards for additions and detached structures. Seven Hills, Inspirada, and Cadence each enforce their own association-level design guidelines. For casitas specifically, setback requirements, lot coverage percentages, and height limits all factor into what can be built and where on the lot. Kingdom & Co. prepares the full HOA application — including architectural renderings and material specifications — during the design phase, so approvals are secured before construction begins.
Start Your Home Addition Henderson Project Today
The first step is a site visit at your Henderson property. For additions and casitas, the on-site evaluation is critical — we assess the home’s structural system, the lot’s available buildable area, and any HOA or zoning constraints specific to your community. From that assessment, our team develops a concept that adds the square footage you need while respecting the architectural character of your home and the standards of your neighborhood.

Frequently Asked Questions
Kingdom & Co. builds casitas and home additions throughout Henderson, including MacDonald Highlands, Green Valley Ranch, Lake Las Vegas, Anthem, Seven Hills, Inspirada, Cadence, and surrounding communities. Our Henderson office is located on Warm Springs Road, and our portfolio includes completed projects across multiple Henderson neighborhoods.
Timeline varies by scope and the HOA approval process in your community. A single-room addition typically takes several months from design through completion. Larger additions and detached casitas requiring new foundations, utility connections, and roofing extend that timeline. Henderson’s permitting and inspection schedule also factors in. Kingdom & Co. provides a detailed project timeline during the design phase.
It depends on your lot size, setback requirements, and lot coverage limits under Henderson’s zoning code and your HOA guidelines. Larger lots in communities like MacDonald Highlands, Anthem, and Seven Hills are more likely to accommodate a detached casita. Smaller lots in newer developments like Inspirada or Cadence may have tighter constraints. Kingdom & Co. evaluates your lot’s buildable area and zoning restrictions during the initial site visit.
A casita is a detached, freestanding structure with its own entrance — typically including a bedroom, bathroom, and sometimes a kitchen. It functions as an independent living space. A room addition is attached to the existing home, expanding the footprint with new bedrooms, living areas, or primary suites. Both require City of Henderson permits and, in most communities, HOA approval. Kingdom & Co. designs and builds both types throughout Henderson.
In most Henderson communities, yes. Guard-gated neighborhoods like MacDonald Highlands and Anthem Country Club maintain architectural review committees with strict standards for additions and detached structures. Master-planned communities like Seven Hills, Inspirada, and Cadence also enforce association-level design guidelines. Kingdom & Co. prepares and submits the full HOA application, including architectural renderings and material specifications, during the design phase.
Yes. Henderson operates its own building department, separate from the City of Las Vegas. Casitas, room additions, and any construction that adds square footage require permits issued through the City of Henderson Community Development Department. The permit process covers foundation, framing, electrical, plumbing, and mechanical work. Kingdom & Co. handles the full Henderson permitting process as part of every addition project.
