From Empty Basement to a Home of Her Own

"From start to finish Tom Bunn and team did a great job. We were looking for a firm fixed price contract and they made it happen. They listened to the concept we had in mind to turn a roughly 1,700 square foot unfinished basement into a customized living space. Their project manager, Anthony, planned out everything from rough drawings all the way down to final selections. There were weekly progress reports given with photos and heads up on what was next. They were very professional and we would definitely go to them and their sub-contractors for future projects."

A Big Question with No Obvious Answer

A Future That Felt Uncertain: Rising retirement costs and long-term care expenses were weighing on the whole family’s financial picture.

A Basement That Wasn’t a Home: The 1,600-square-foot space had the footprint for a full living suite but none of the rooms, systems, or finishes to make it livable.

Two Households, One HVAC: A single heating and cooling system couldn’t fairly serve a grandmother who likes the house warm and a younger family that prefers it cool.

A Design She Couldn’t Quite Picture: Patricia struggled to visualize the layout on paper, which made committing to finishes and final decisions feel overwhelming.

A Self-Sufficient Suite, Thoughtfully Laid Out

Our team reimagined the entire basement using 2D and 3D design alongside material samples, then set up showroom appointments so Patricia could see and touch appliances, countertops, and finishes in person. The result is a full home within a home: living room, kitchen, laundry, master suite, and storage, all on its own HVAC zone with walkout access to the outdoors.

The Details That Made It Hers

Modern bathroom with light blue walls, white vanity, marble countertop, wooden floor, and glass shower

A Low-Maintenance Walk-In Shower

A built-in seat, grab bar, and easy-clean surfaces mean Patricia's bathroom supports her today and will keep supporting her as her needs change.

Laundry room with stacked LG washer/dryer, white cabinets, wood countertop, light blue walls, and wood floor

A Laundry Room of Her Own

A private, full-size stacked washer and dryer with custom cabinetry means Patricia never has to haul a basket up the stairs or share a schedule with a busy family of four.
