The story is typical: The owners of this 1,500-square-foot English Tudor needed to expand their living space, but setbacks and architectural controls in their Denver historic district restricted what could be done with an addition. So they turned to the 1,280-square-foot basement as the likeliest candidate.
"It was dark and restricted, not a place where you would want to spend much time," says remodeler Bill Kennedy of Basements and Beyond.
The homeowners wanted to transform the claustrophobic cellar into an appealing living area that included a family room, bedroom, laundry facility and wine room. The challenges: code violations such as insulation with asbestos, the lack of an egress window, and a ceiling clearance of only 76 inches.
The first step required roughing in an opening for a 4x4-foot egress window at the rear of the house. The window became Basements and Beyond's primary access for demolition and reconstruction.
"We couldn't bring in mechanical equipment due to a new driveway and no alley access," says Kennedy. "Everything had to come in and out of a 4 by 4 hole."
He hired a specialist to remove asbestos insulation around the old furnace and ductwork. Then demolition began in earnest. "Down to the bones," Kennedy says.
To increase ceiling height, Basements and Beyond began by digging out enough of the old concrete flooring to pour new footings for steel posts to support four new steel I-beams. Once the I-beams were in place, workers removed old brick support walls to open up the space. Then they removed the remainder of the concrete floor and hand-dug the dirt underneath: 8 inches down across the entire 1,280 square feet. They wheel-barrowed the dirt out to the street.
In the process, they removed the existing underground plumbing, then lowered it. The crew also had to install an ejector system for sewage because of the change in fall from the sewer line to the street. Finally, they pumped concrete for the new floor through a small window in the front of the house.
Kennedy carefully monitored feasibility on the project. "A lot of engineering was done first," he says. "No surprises." The project cost $134,000 and almost doubled the size of viable living space in the house.
