HOME ADDITIONS

Home Additions in Overland Park & Kansas City

When you love your location but the house needs more room, moving is not the only answer. Built by Design plans and builds additions with one design-build team handling the design, scope, selections, and construction path together.

ADD ON WITH A PLAN

More square footage only works when the old home and new space feel like one decision.

A home addition starts with a simple feeling: the house is close, but it no longer fits. Maybe the kitchen is too tight for the way people gather now. Maybe a main-level suite would make the home easier to live in long term. Maybe a second story, family room, or connected outdoor living area could give the home breathing room without leaving the neighborhood, schools, trees, and daily routes you already know.

Built by Design helps Overland Park, Johnson County, and Kansas City homeowners study that choice before momentum takes over. An addition is not only a bigger footprint. It touches rooflines, foundations, structure, exterior materials, windows, mechanical systems, interior finishes, and the way people move through the home. The design-build approach keeps those decisions in one conversation, so the design is shaped by construction realities and the construction is guided by the design intent.

Founded in 2004 by Mike Schwartz, Built by Design brings more than 22 years of remodeling experience to homes across Overland Park, Leawood, Johnson County, and the Kansas City area. If the question is whether to add on or move, the right next step is to walk the house with a team that understands both the dream and the structure behind it.

WHAT WE BUILD

Types of Additions We Build

Every addition has to respect the existing house. The details change from project to project, but the goal stays the same: new space that feels useful, durable, and intentionally tied to the home around it.

Room additions

A room addition may solve for a larger kitchen, a connected living room, a dining extension, utility space, or the everyday square footage the original plan never had.

Primary suite additions

Primary suite planning looks at privacy, bathroom layout, closet space, window placement, and how the new suite should connect without feeling tucked on as an afterthought.

Second-story additions

Building upward can protect yard space or work around a tight lot, but it also brings roof, stair, weather, and structural questions that need early design-build review.

Expanded living spaces

Some additions are about changing the way the main level lives, with larger gathering rooms, better sightlines, refreshed fireplaces, and kitchens that finally have enough room to work.

Connected outdoor living

When the project includes patios, covered areas, exterior updates, or backyard living, the indoor plan and outdoor plan need to feel related from the start.

If you are still sorting out the category, start with the broader remodeling services overview, then look at how additions fit the specific homes and neighborhoods around Overland Park.

DESIGN-BUILD

Our Design-Build Process for Additions

Additions involve more hidden work than many homeowners expect. A wall opening can change a beam. A roofline can change ceiling heights. A second-story idea can change stairs, weather protection, and structural review. Built by Design is set up for that kind of coordination because design and construction planning happen together.

For a deeper look at vertical planning, read the Built by Design guide to second-story additions. It covers structure, rooflines, stairs, utilities, and why feasibility has to come before a pretty drawing.

  1. 1

    Consultation at your home

    Built by Design comes to you, walks the space, listens to what is missing, and looks at how the existing home is asking to change.

  2. 2

    Design and feasibility

    The early plan studies the new room, the rooms it affects, circulation, daylight, rooflines, exterior materials, utilities, and how the addition should feel from inside and outside.

  3. 3

    Engineering and permitting

    Additions involve structure, foundations, roof connections, and city requirements. Built by Design uses the design-build process to keep those questions tied to the plan before construction begins.

  4. 4

    Selections and scope

    Cabinetry, flooring, tile, lighting, fixtures, doors, windows, and exterior finishes are coordinated with the scope so pricing and construction expectations stay connected.

  5. 5

    Construction and communication

    The build moves through protection, demolition, structural work, rough-ins, exterior tie-ins, finishes, and punch-list details with one team responsible for the whole path.

PLAN THE CONNECTIONS

The best addition does not announce where the old house stopped.

A good room addition can change daily life, but only when the transition is handled with care. Floor heights, trim profiles, roof massing, exterior materials, window rhythm, HVAC paths, lighting, storage, and furniture clearances all affect whether the finished space feels natural.

That is why Built by Design talks about how the addition should live before the work is narrowed to a list of products. A kitchen expansion is also a traffic pattern. A living room addition is also a ceiling volume, fireplace wall, and view from the rooms around it. A primary suite is also privacy, storage, plumbing, and the quiet route you take at the beginning and end of the day.

FAQ

Home Addition Questions

Practical planning context for your project. Your project team confirms what applies after a walkthrough and written scope review.

Is it cheaper to add on or move?

It depends on the home, the lot, the market, and the kind of space you need. Adding on can make sense when you love your location and the existing home is worth improving. Moving can make sense when the structure, lot, or neighborhood limits the project too much. Built by Design starts by looking at the home and the goal so the conversation is grounded in real scope instead of a generic comparison.

How long does a home addition take?

Timeline depends on design, engineering, permitting, structural work, weather, materials, selections, and how much of the existing home is affected. The Overland Park room addition in the portfolio took 16 weeks, but that is one documented project, not a promise for every addition. Built by Design discusses schedule after the plan and scope are clearer.

Can you add a second story to an existing home?

Sometimes. A second-story addition depends on the existing foundation, framing, roof, stairs, utilities, layout, and the way the home can be protected during work. It can be a smart way to gain space when the lot is tight, but feasibility should be reviewed before a homeowner commits to drawings.

What affects the cost of a room addition?

Cost is shaped by size, foundation work, structural changes, rooflines, windows, exterior materials, mechanical systems, plumbing, electrical work, interior finishes, cabinetry, tile, flooring, and how cleanly the new space connects to the old home. Early planning helps separate must-have scope from nice-to-have details.

Does Built by Design handle design and construction?

Yes. Built by Design is a design-build remodeler, so one team helps with planning, design direction, selections, scope, construction, and communication from the first walkthrough through the finished addition.
