People have been asking us for a long time if we sell tiny house building plans. Meeting that need is something we’ve always wanted to do, but we felt it was important to wait until we had something truly unique and valuable to offer the tiny house community. We are thrilled to announce that Seattle Tiny Homes is now offering comprehensive building plans! They are based on our most popular model – the Alki – and we believe these are the most comprehensive tiny house plans available today for do-it-yourself builders.
To bring the plans to life, we collaborated with Saul Rip Hansen, the founder of the Collaborative Tiny House project. An experienced architectural designer who is passionate about tiny houses, Saul pushed architectural design tools to the limit to produce plans that are intricately detailed yet easy to understand.

Our Goal: Solve the Biggest Challenge Tiny House Builders Face
As we talked to tiny house do-it-yourself builders over the years, one thing became clear: complicated systems like plumbing and technical details like affixing the house frame to the trailer are the biggest barriers to successfully building your own tiny home.
Our professional building team at Seattle Tiny Homes has spent years solving these challenges. And now we’re sharing everything we’ve learned in these plans.
Our complete set of plans – over 80 pages long – shows you how to frame your home and securely fasten the frame to the trailer. It includes comprehensive plans for all your home’s most complicated systems: electrical, plumbing, propane, and HVAC. We’ve even included a step-by-step building guide so you always know what to do next.
If you don’t need the complete set of plans, you can purchase different system modules individually. For example, you can purchase just the electrical plan . . . or the plumbing plan . . . whatever systems you need.
Each module is extremely detailed and includes a list of tools needed, a materials list, schematics, cutaways, perspectives and pro tips.
We truly believe these plans give you the best possible opportunity to succeed.
Build the Alki: The Perfect Tiny Home

These plans are for Alki, a model that has really been refined over the years. At 24 feet long, it’s just the right length for most people. We’ve designed it to be full of light, and the first thing people say when they step inside is, “Oh, I didn’t know a tiny home could feel so spacious!”
The Alki has a full kitchen, a full bathroom, and even space for a washer and dryer. Sleep in one of the two lofts or a convertible bed on the main level. It is one of our most versatile and practical models.
With clean, contemporary styling, the Alki is eye-catching and beautiful. We believe you’ll love it just as much as we do. Check out our new plans now! Thank you for your support.
