TWThorne Whitlock Architects

Architecture · Portland, Oregon

Quiet buildings, made to last a long time.

A small architecture practice designing houses, interiors and modest public buildings in the Pacific Northwest. We start with the site, the light and the way you want to live, and keep the rest as simple as we can.

Approach

Three things we hold to.

  1. i.

    Site First

    We walk the site at different hours before we draw anything. The sun, the wind and the neighbors decide more than we do.

  2. ii.

    Fewer Materials

    Timber, concrete, lime and glass, used honestly. Fewer materials means fewer things to wear out and fewer to fix.

  3. iii.

    Built to Be Kept

    We design for the second and third owners too: rooms that adapt, details that age well, and running costs you can live with.
