Interior of a sunroom by All Under One Roof with a stone fireplace, tile floor and windows on all sides, Kansas City

Sunrooms & Three-Season Rooms

Overview

Glass walls. Golden light. A room for every season.

A well-built sunroom adds usable square footage without the cost of a full addition. All Under One Roof designs and builds glass sunrooms and three-season rooms for Kansas City homes — from window-wrapped rooms that stretch spring and fall to fully conditioned four-season sunrooms you can enjoy in January.

These are structural projects, not bolt-ons. A sunroom done right needs proper footings, a roofline that ties into the existing house cleanly, and window and insulation choices matched to how you plan to use the room. As a design-build firm with real structural expertise, we engineer those details up front so the finished space feels like it was always part of the house.

Prefer open-air living? We also build custom screened porches as their own dedicated service — and some clients start with a porch designed to convert into a three-season room down the road. Either way, one accountable team manages your project from design and permitting through construction and final walkthrough.

Frequently Asked Questions

Sunrooms generally run about $100 to $350 per square foot, so a three-season room often lands between roughly $15,000 and $70,000, while fully glass four-season rooms cost more. A screened porch is the most budget-friendly option. Size, foundation, glass, and insulation drive the number, and we'll price your exact project after a free consultation.

"All Under One Roof did a great job on our one day project which involved removing an old JennAir downdraft cooktop and installing a new Hauslane built-in range hood and KitchenAid gas cooktop. They installed the hood into our existing cabinetry and vented it to the outside of the house. Very happy with the results."

"Since a picture speaks a thousand words, I really don’t need to write a review. But I will say this is the 3rd project we’ve done in 7 months with AUOR, and the 3rd time we’ve been blown away by the end result. Our primary bath remodel was on time, on budget and on point. Bryan and Andrea are fantastic to work with. Their professionalism and craftsmanship are second to none. 100% recommend!"

"Too bad we can only give 5 Stars. All Under One Roof deserves a lot more. We asked to have a sliding glass door and a regular exterior door replaced and sealed (to prevent water intrusion). While doing the work AUOR discovered water damage that was covered up by a previous contractor (for the previous owner of our home) and investigated until the full extent of the structural damage was uncovered and repaired correctly. Bryan and his team are experts and it showed. They made sure our home was safe and structurally sound. AND, they communicated with us every step of the way. AND, all of the damages and repairs were documented which helped us recoup costs in the aftermath of these surprise findings. I wish all contractors were as ethical and competent as Bryan and the AUOR team!"

"The team did great work on re-designing and replacing two large decks we have, fixing dry-rot hidden by the old decks, repainted all of the buildings, and did some stone work. The team was very professional, working 6 days a week and the work quality was top-notch. Bryan and Andrea were both very communicative and clearly had our best interests, as their clients, in the front of their mind always. Looking forward to doing future projects with them!"

"All Under One Roof has done four large projects for us. One was an extensive interior project that involved wall removals and a complete first-floor renovation, and another was an interior renovation on a lake cabin. Two were exterior projects that included upstairs decks, ground-level patios, staircases, and fire pits. In each case, AUOR worked closely with us before and throughout the projects to determine and meet our project needs and goals. They communicated constantly throughout the projects and were very responsive to what we wanted and needed. The end results are perfect! I highly recommend All Under One Roof!"

"Bryan and his crew are total pros. Always on time, work is perfect, cleaned up when done, and communication is excellent. I'm on house #6 and have a long time span of working with builders and contractors. Considering this, I'd rank All Under One as a top tier provider in customer support and quality of work, without question. Every one of his team knew what they were doing and wasted zero time getting projects done. Even more rare, they are all FRIENDLY. I highly recommend this firm."

"From the very beginning, Bryan demonstrated exceptional professionalism and support in helping me outline the plans, materials, and timelines for my deck remodel. He was responsive to all inquiries and took the time to walk me through multiple scenarios to ensure the project was completed to the highest standard. Even when I initially intended to complete the work myself, Bryan generously offered practical advice and guidance, highlighting key considerations and potential challenges throughout the process. When I ultimately decided to bring in professional help, Bryan and his team responded promptly—arriving the very next day—and completed the project with impressive speed and efficiency. His crew was courteous, thorough, and respectful of my property, leaving the backyard clean and safe for both my children and pets. Their attention to detail and customer care truly stood out. I highly recommend Bryan and his team for any interior or exterior renovation project. Their expertise, reliability, and commitment to quality are second to none."
