Renovation & Restoration Architecture in Seattle, WA

Transforming an existing building requires a different kind of expertise than designing from scratch. You must read what is already there — understand its structure, its character, its potential — and bring it forward. Piper Cole Architects has been doing this in the Seattle metro area for over 25 years, delivering renovations and restorations that honor what is special about a space while making it fully contemporary.

The Challenge of Renovation

Renovation projects often reveal surprises — structural conditions, outdated systems, materials that must be handled carefully. Our experience across hundreds of existing-building projects means we plan for the unexpected and keep your project on schedule and budget even when the walls reveal something new.
