Home additions in Redmond.
Redmond’s houses are better than their square footage — good lots, solid bones, and floor plans drawn for a smaller life than the one being lived in them. Go Far Construction builds additions across Redmond: ground-floor room additions, primary suites, second stories, and bump-outs, engineered properly and finished so the new space reads as original to the house, from a family-owned, licensed Washington general contractor with 12+ years on homes across King and Snohomish counties.
The housing stock sets the work. The ’70s ranches and split-entries of Education Hill and Grass Lawn take naturally to building out — a primary suite or a family room off the kitchen on lots that still have room to give. In the ’80s and ’90s two-stories off Avondale and up on English Hill, the plan is usually right but a room short: a bump-out, a bonus room over the garage, or a second story where the lot can’t grow; our second-story addition guide covers building up, and the home additions service page covers the full range.
On budget: most additions in this market price out between roughly $300 and $550 per square foot, with complex or high-end projects going beyond that — an addition builds new house from the foundation up, which is why it prices differently than a remodel. Our home addition cost guide breaks down the ranges by addition type, and our addition vs. moving guide runs the numbers against buying the next house — in Redmond, where the jump to the next-size-up house is among the steepest in the region, adding on usually wins that comparison outright.
The craft is matching the house: tying new foundation lines, rooflines, and siding into a ’70s ranch or a ’90s two-story so the addition reads as original — the same houses we open up in our Redmond kitchen and bathroom remodeling work. Every addition is permitted through the City of Redmond with structural review; we prepare and track the application, carry fees in an itemized written estimate, and meet every inspector on site, as on all our Redmond projects. If the space you need is a separate unit rather than more house, our Redmond ADU & DADU page covers that route.

Redmond home addition questions
How much does a home addition cost in Redmond?
In this market, most additions price out between roughly $300 and $550 per square foot, with complex or high-end projects going beyond that. A bump-out is the entry point, a single-room addition typically lands in the low-to-mid six figures, and primary suites cost more per square foot because of the plumbing and tile involved. Every project gets an itemized written estimate.
Should I build up or out in Redmond?
On Education Hill and Grass Lawn ranches the lot usually still has room, so building out — a primary suite or family room — is the simpler route. On the ’80s–’90s two-stories, a bump-out or over-garage bonus room often solves it; a full second story wins only where the lot can’t grow. We walk the options with real numbers before design begins.
Do I need a permit for a home addition in Redmond?
Yes — every addition needs a building permit through the City of Redmond, and most involve structural review. We prepare and track the application, include fees in your itemized written estimate, and meet every inspector on site.
Is an addition worth it in Redmond, or should we just move?
Run the real numbers and Redmond is one of the strongest addition markets anywhere: the gap between your house and the next-size-up house is usually far wider than the cost of building the room you’re missing — before counting moving costs and a new mortgage rate. Our addition vs. moving guide walks the math.
