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.

HOME ADDITIONS
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
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.
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 planning looks at privacy, bathroom layout, closet space, window placement, and how the new suite should connect without feeling tucked on as an afterthought.
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.
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.
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.
RECENT WORK
Finished work gives the clearest view of what addition planning has to solve. These portfolio projects show real Built by Design scope, from new living space to connected indoor-outdoor planning.

Overland Park, KS
A 16-week Overland Park room addition added roughly 1,000 square feet, opened up the kitchen, created a huge living room, refreshed the fireplace, and added a mudroom-laundry area with a tiled dog wash.

Overland Park, KS
This case study shows how a finished lower level, exterior updates, and outdoor living space can be planned as connected parts of the home instead of separate projects.
DESIGN-BUILD
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.
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.
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.
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.
Cabinetry, flooring, tile, lighting, fixtures, doors, windows, and exterior finishes are coordinated with the scope so pricing and construction expectations stay connected.
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
Practical planning context for your project. Your project team confirms what applies after a walkthrough and written scope review.
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.
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.
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.
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.
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.
