Seattle Basement Remodel Conversion
This project involved a full basement remodel and functional conversion of an existing basement space in Seattle. The basement was previously unfinished and not compliant for bedroom use. NBE LLC transformed the space into a fully code-compliant, multi-purpose living area that includes a legal bedroom, new laundry room, remodeled bathroom, sauna, and a dedicated home theater/media room.
Existing Conditions:
- Basement was not configured for bedroom use and lacked required egress.
- Structural support layout limited open space and functional flow.
- No dedicated laundry room, sauna, or media infrastructure.
- Outdated finishes and non-functional layout.
Scope of Work / Key Challenges:
- Structural reconfiguration requiring relocation of support posts and beams.
- New concrete work, including cutting slabs and pouring new concrete pads and footings.
- Creating a code-compliant bedroom with a new egress window and window well.
- Coordinating plumbing, electrical, and HVAC upgrades throughout the basement.
- Integrating specialty spaces such as a sauna and a sound-treated media room.
Solutions & Work Performed by NBE LLC:
- Relocated multiple structural posts and beams, coordinated with a structural engineer and inspections.
- Cut existing concrete and poured new footings and pads to support the revised layout.
- Installed a new egress window, including concrete cutting, window well installation, drainage, and finishing to meet Seattle code requirements.
- Built a new bedroom, including framing, insulation, drywall, finishes, doors, and trim.
- Created a new laundry room with new water supply, drain, venting, electrical circuits, and flooring.
- Fully remodeled the bathroom, including plumbing relocations, waterproofing, tile installation, custom shower, ventilation, and fixtures.
- Constructed a custom sauna space, including framing, electrical rough-in, ventilation, and finish coordination.
- Designed and built a home theater / media room, including: - Acoustic insulation and sound treatment.
- Custom speaker enclosures and wiring pathways.
- Projector wiring and dedicated electrical circuits.
- Completed full interior finishes throughout the basement, including drywall, painting, flooring, trim, doors, and lighting.
Result:
The basement was successfully converted into a fully functional, code-compliant living space featuring a legal bedroom, modern bathroom, laundry room, sauna, and a high-end home theater. Structural challenges and complex coordination were resolved through careful planning, engineering collaboration, and close inspection coordination. The finished space significantly increased both the usability and long-term value of the home.
