For fastest and best experience, we recommend that you call us directly, 913 642 3337, or come to our Design showroom, conveniently located on 87th Street across from Louisburg Square. (appointments encouraged, not required of course.) Yes we are full service licensed general contractors for Johnson County, but foremost we are about great design! Our showroom is where we start with ideas, and then we follow up with home appointments. Who are we exactly? We’re your kitchen's all-in-one full service remodeling answer for peace of mind. Kitchen remodeling is complex because many diverse skills must come together, correctly and without slippage. At Armstrong Kitchens we combine our wide range of abilities and experience for your best outcome, and we’ve had many decades to pull it all together. We are unique in being all of the following: -Interior Designers: each designer has a degree in Interior Design and is highly experienced, to make sure your new update looks like you want it to, and so that it fits well into your home. -NKBA Kitchen & Bath Designers: each designer is fully trained and NKBA accredited, to handle the specification complexities and minute technical details of all the products you will need. -Licensed General Contractor: We make sure your wonderful new room comes together the way its supposed to, by putting it together ourselves. We are not only licensed for General Contracting, but also Electrical & Mechanical and lead paint abatement. Like the old saying goes “If you want something done right…” In our 72 year history as a multi-generational family business, this has been the proven recipe for success.

"Look no further! Our kitchen remodel was top to bottom and even included tear-out of ceiling soffits. From the start: Pricing was competitive with an easy to understand estimate. Classic or trendy, Kristeen teaches at a local college and knows what’s out there and what we could expect. Communication was easy and prompt. Everyone was GREAT to work with and the job was completed ON TIME. They go ABOVE & BEYOND! Over a year after we were done our “Smart” faucet motor went out. At no charge, father and son came out and switched it out for us. We have done our share of remodeling and wish we had found them sooner. I LOVE my kitchen!"

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
