Luxury Home Additions

Luxury home additions in Johnson County and Kansas City crafted with precision and purpose.

Get Started With Your Remodel

More than extra space - this is how you reimagine the way you live.

Your home was never meant to stay static. Whether you’re adding a second story, expanding your main level, or designing a private suite that feels like a boutique hotel.

Built by Design crafts additions that look original to your home – only better. Every line, every finish, and every detail is intentionally designed to feel seamless, elevated, and entirely your own.

Spaces with Purpose, Designed Around You

Maybe you’re building a luxury primary suite with spa-level amenities.
Maybe you want a second-story addition to make room for your growing family.
Maybe it’s time to create a true indoor–outdoor living space for entertaining.

Whatever your vision, we design it to align perfectly with how you live – structurally, stylistically, and emotionally.

  • Second Story Additions & Full-Home Expansions – engineered for strength, built for longevity, designed to look like the home was always meant to be this way.
  • Luxury Suite Additions – primary suites, guest retreats, multi-generational living spaces with hotel-level finishes.
  • Lifestyle Wings – sunrooms, gym wings, pool houses, entertainment pavilions, offices, or hobby spaces that create daily joy.
  • Architectural Enhancements – new staircases, rooflines, garages with living quarters, and expanded entryways that reshape your home’s presence and value.

Architectural Integrity Meets Luxury Design

A home addition shouldn’t simply connect to your floorplan – it should elevate it.

Our team manages every technical and aesthetic detail:

  • Structural engineering and permitting
  • Custom architecture and layout design
  • Integrated mechanicals, sound, and lighting plans
  • Seamless exterior blending with your existing façade
  • Interior finishes chosen to match – or redefine – your style

The result? A space that doesn’t just “meet code.” It meets your standards.

Built by Design nailed our home addition — it blends in perfectly, looks better than the original, and the whole process was smooth and organized..

“We hired Built by Design for an add on to our house and they nailed it. The new space blends in perfectly. It’s like it was always part of the home, but looks even better than the original build. The process was organized, no surprises, and their team actually listened to what we wanted. It’s the kind of upgrade that instantly adds value and makes you excited to come home every day.”

Testimonial

Built By Design nailed our room addition project

“Mike, Kristen and Dave from Built By Design are the team that rocks remodeling projects. They did a two room addition and revamped the outdoor area. The communication was very good. We knew about every delay and why. They also were very good to give us the schedule and when to expect things to be finished! As a repeat customer I will always use them for all my remodeling projects!”

Testimonial

Built by Design made our home addition looks like it came straight from a luxury magazine

“We had Built by Design do a full addition on our home and the entire experience was seamless. The quality is unbelievable – every finish looks like it belongs in a luxury magazine, but the team was down-to-earth, easy to work with, and kept us updated through every step. It feels like a completely new home, and we couldn’t be happier with how it turned out.”
