Free in-home consultation across the KC metro — feasibility, engineering, and a fixed-price proposal.
Feasibility & Design
We evaluate your lot, setbacks, soil conditions, and how the addition ties into the existing structure. Architectural plans are drafted around your layout, budget, and finish goals.
Engineering & Permitting
Structural engineering is completed and we submit for permits with your specific city or county. Because our clay soils move with moisture, foundation design gets particular attention here.
Foundation & Framing
The foundation is excavated and poured below the frost line, framing ties the addition into the existing structure, and the new roof is integrated with proper flashing and drainage.
Mechanicals, Finishes & Handoff
Plumbing, electrical, HVAC, insulation, drywall, flooring, trim, paint, and fixtures are completed. We match interior and exterior finishes to the existing home, pass final inspections, and hand off the space.

Outgrowing a home you love — in an established metro suburb where you want to stay — is a common reason homeowners add on rather than move. An addition done right looks like it was always part of the house: the foundation is engineered for our soils, the roofline ties in cleanly, and the new brick or siding blends with the original.
Foundations Engineered for Expansive Clay
The clay soils under most of the metro move with moisture, so an addition can't sit on a generic footing. We design the foundation for the site — poured below the frost line, reinforced, and drained — so the new structure stays stable and tied to the existing home through the seasonal swings that shift under-built additions. On a second story, we have a structural engineer confirm the existing foundation and framing can carry the added load before we build up.
Matching Brick, Siding & Rooflines
A lot of KC homes are brick or a particular siding profile, and the difference between an addition that disappears into the house and one that looks bolted on is in the match. We source materials to blend the exterior as closely as possible and integrate the new roof with proper flashing and drainage. Exact brick matches on older homes aren't always possible — when that comes up, we walk you through the options before committing.
Second Stories, Bump-Outs & In-Law Suites
Additions take many forms: a single bedroom or family room, a kitchen or bath bump-out, a full second story, or a private in-law suite for multigenerational living. Each ties new framing, mechanicals, and finishes into the existing home. When an addition is part of a broader project, we often coordinate it with whole-home remodeling or manage the entire build as your general contractor.
Room additions often tie into kitchen, bathroom, and whole-home work so the new space blends seamlessly with the existing home.

George S · Your Project Manager
Can you match the addition to my existing brick or siding?
Matching is a core part of the work. Many KC homes are brick or a specific siding profile, and we source materials to blend the addition into the original as closely as possible so it doesn't read as an obvious bolt-on. Exact brick matches on older homes can be a challenge, and we'll talk through options if that comes up.
Will the clay soil be a problem for a new foundation?
It's a real consideration, which is why additions here get engineered foundations rather than a generic footing. Expansive clay expands and contracts with moisture, so proper depth, reinforcement, and drainage are designed in from the start to keep the addition stable and tied to the existing home.
Can you add a second story to my home?
Often, yes — it depends on whether the existing foundation and framing can carry the added load. We have a structural engineer assess that first. If reinforcement is needed, we coordinate it as part of the project.
Do additions require permits?
Yes. Additions require permits, structural engineering, and a sequence of inspections, and the details vary between Missouri and Kansas jurisdictions. We manage the permitting and inspections for your location.

Do additions require permits in both Missouri and Kansas jurisdictions?
Yes. Additions require permits, structural engineering, and a sequence of inspections, and the details differ between Missouri and Kansas cities across the metro. We manage the permitting, engineering coordination, and inspections for your specific location.
We provide home additions to homeowners across the Kansas City metro on both sides of the state line. Each community has its own dedicated page with local permitting, climate, and project detail — and each metro hub covers the surrounding areas we also serve.
