Local fit

Why Columbia City projects need more than a generic bid.

Columbia City and nearby South Seattle neighborhoods include older homes, compact lots, transit access, and a lot of opportunity for thoughtful additions and ADUs.

Rough Cost Calculator

Start with a realistic planning range.

This is not a bid. It is a fast way to help a homeowner understand whether a remodel, addition, ADU, or feasibility study is in the right universe before scheduling a real Rudd conversation.

Ballpark range

$400,000 – $740,000

This is a rough ballpark planning range, not a bid. Site conditions, structural work, permitting, utilities, finishes, access, and scope can move the real number materially.

How to start

Bring the messy version. We’ll help sort it out.

You do not need perfect drawings or a finished scope to talk with Rudd. A rough idea, a few photos, a wish list, or a question about whether the project makes sense is enough for a first conversation.

  • • Tell us what is not working about the house today.
  • • Share the rough project type, timing, and budget comfort zone if you have one.
  • • Attach plans, photos, inspiration images, or old permit drawings if they help explain the idea.

Tell us about the project

Optional — plans, sketches, inspiration photos. PDFs, images, or CAD files. Up to 4 MB total.

Tell us you came from the Columbia City page and include the rough scope, timing, and any photos or plans you already have.
