A Seattle Gut-Rehab Targeting LEED Certification

Homeowner Collen Groll of O’Brien & Company has spent the last 5 years bringing this 1919 Seattle bungalow back to life, and it’s now for sale! Remodeled from the studs-out for superior energy efficiency, increased comfort, and flexible, open living spaces, and is now going to achieve LEED for Homes Silver Certification.

Exterior

3 bedroom/2.5 baths, 3-stories, 2,390 sf home, 3,530 sf lot and 1-car garage. Secluded amongst trees, yet blocks from Lake Washington & Leschi town center.

Design

This home was originally built in 1919, and is 2-stories with a basement. When purchased in 2007, the house was in poor repair, extremely leaky, and was not functionally well laid out. It was essentially a stripped shell with exposed floor joists and wall cavities. The second floor included a typical gable roof with a small window at either end, and because the south side of the house was already at the set-back line, there was no way to extend the roof line.

The floor plan was redesigned to include functional, adaptable spaces. In order to accommodate three bedrooms and extend the ceiling on the second floor, the roof peak was raised, which increased the pitch of the roof line. A crow’s nest (future yoga and meditation studio) was added, which allowed an additional view of Lake Washington and a special place for rejuvenation.

Goals

The priorities for this project were improved envelope and energy efficiency. Additionally, homeowner Colleen, wanted to incorporate salvaged products and healthy finishes where possible.

In order for this project to pursue LEED for Homes certification a complete gut rehab was necessary, as partial or even substantial remodels are not eligible. Additionally all systems and components (e.g. HVAC, water heater, windows) are required to be replaced and exterior walls must be open to allow for a Thermal Bypass Inspection.
