Nordic Inspired Backyard
Offices + Studios

At ASUNTO we specialize in custom-built accessory buildings—studios, home offices, guest suites, and cabins built to your specific needs and end use.

The ASUNTO Classic Studio

The ASUNTO Gable and Lean-To Roof Studio lineup include the Classic, the Custom, and the Premium Studio models, which also provide starting points for further customization, upgrades, and finishing options. 

The Studio Classic Build Package outlined below includes everything you need to start working, creating, or simply enjoying your backyard studio space in comfort all year round.

ASUNTO Studios are custom-built to last. All of our buildings are framed, insulated and waterproofed to BC Building Code Standards (CSA A277). We include a customizable electrical package and our building process allows for building customization depending on your end use and needs. For even more convenience, ask about loft additions and plumbing options.
