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.

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.
