Home additions in Shoreline.
Shoreline is a one-story city — the 1950s and ’60s ramblers it was built on came small, on lots with room to grow, which makes an addition the most natural project here. Go Far Construction builds additions across Shoreline: ground-floor room additions, primary suites, added bathrooms, and second stories, engineered properly and finished so the new space reads as original to the house, from a family-owned, licensed Washington general contractor based ten minutes north in Lynnwood.
From Richmond Beach to Echo Lake, Meridian Park, and Ridgecrest, the mid-century rambler sets the assignment, and the up-or-out question usually tips out: a primary suite, a family room off the kitchen, or the bump-out that finally adds a second bathroom to a one-bath rambler. Where the lot is tight — or a second story would capture a Sound view on the Richmond Beach side — building up wins instead; our second-story addition guide covers what that takes, 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 — with light rail now running from Shoreline’s two stations, owners who once planned to sell are choosing to stay and add on instead — and the numbers usually back them up.
The craft is matching the rambler: extending a low roofline, picking up the brick and lap siding, and holding mid-century proportions so the addition reads as original — the same houses we open up in our Shoreline kitchen and bathroom remodeling work. Every addition is permitted through the City of Shoreline 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 Shoreline projects. If the space you need is a separate unit rather than more house, our Shoreline ADU & DADU page covers that route.
What we build in Shoreline
Shoreline home addition questions
How much does a home addition cost in Shoreline?
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 Shoreline?
Shoreline’s ramblers sit on usable mid-century lots, so building out — a primary suite or family room — is usually the simpler, cheaper route. A second story wins where the lot is tight or where it would capture a Sound view on the Richmond Beach side. We walk both options with real numbers before design begins.
Do I need a permit for a home addition in Shoreline?
Yes — every addition needs a building permit through the City of Shoreline, and most involve structural review. We prepare and track the application, include fees in your itemized written estimate, and meet every inspector on site.
Can you add a second bathroom to a one-bath Shoreline rambler?
Yes — it’s one of the most common Shoreline projects we see. Sometimes the second bath fits inside the existing footprint; when it doesn’t, a modest bump-out off the bedroom wing solves it. Either way it’s the single upgrade that changes how a one-bath rambler lives, and it pairs naturally with our Shoreline bathroom remodeling work.
