If you’ve ever thought about building your own spiral staircase but don’t know where to start, Ben Uyeda of HomeMade Modern has just brought you one step closer to making it a reality with this newly published instructional video and free CAD files.

Applying the knowledge and skill sets he developed at Cornell University’s architecture school, Uyeda explores cross-sections of digital fabrication and traditional construction techniques to offer do-it-yourself design ideas, templates and instruction to the masses. For this segment, he combines CNC milling of furniture-grade plywood with gluing, clamping, sanding and driving using traditional hand tools, resulting in a nifty stacked-plywood spiral stair (sans handrail, soon to come) anchored to a standard steel beam.

The HomeMade Modern blog, which was founded by the architect, will soon make available free CAD files for the 12 shapes that were CNC-cut into ¾-inch plywood sheets along with the full photo-and-text tutorial and list of tools and supplies. Though time-and-labor intensive, the project was significantly cheaper than most prefabricated metal spiral staircases, he estimates.

Uyeda also announced that HomeMade Modern has signed a deal with Autodesk to work in the company’s new BUILD Space, a state-of-the-art workshop in Boston dedicated to research and digital-fabrication and construction-automation prototyping for the AEC industry. And the architect is inviting the A&D community to suggest and possibly even collaborate on DIY ideas for him to tackle at the Autodesk facility.
