Prefab Guest Houses & Modular Home Additions

A Studio Shed modular home addition is a simple and efficient alternative to a costly and time-consuming home remodel. Get the space you need in a fraction of the time, and for far less than you might think.


Almost all of us could use a little more space in our lives. But we don’t need just any space – we need the right space. For those who need to accommodate a growing family, have a creative workspace, or work from home, a detached, turnkey modular home addition or prefab guest house from Studio Shed is a popular and cost-effective alternative to expensive and time-consuming remodels and additions.

Our panelized and freestanding turnkey backyard buildings eliminate the need for involved foundation work and integration to an existing structure, expensive architectural and drafting costs, and for our most popular sizes (10×12 and smaller), even the long wait at the building department.

In addition, you’ll make use of your backyard in new ways as you integrate your indoor and outdoor living spaces. You’ll get far more room than just the square footage of your Studio Shed. Studio Shed Signature Series units with Lifestyle interiors are built to the same (or better) standard than new home construction. High-quality double or triple pane (optional) glass, healthy denim insulation, finished flooring and lighting create a space that’s truly an extension of your home.

All Studio Sheds from our Signature Series can be customized by you in our 3D Configurator. Pick and choose your window and door options, layout, and even color choices. Our online build tool gives you the freedom to design the manufactured home space you need, along with a fixed price for your Studio Shed, all options, delivery, and installation. Unlike a remodeling bid from a contractor, this is not an estimate. It’s a price you can be confident will not grow as your project commences.

“Originally we considered building an addition on the house. But the budget estimates came in at $135,000, and we didn’t want to spend that much when all we really needed was one extra room.”

– Marty M. Denver, CO

The all-in cost of a Studio Shed is typically a fraction of the cost of a remodel or addition. Our most popular finished spaces are installed in less than one week, making it the fastest way to gain the extra space you need. Studio Sheds can be equipped with plumbing for guest houses and accessory dwelling units (ADUs). Many of our certified installers can even work with you directly to perform this work alongside the installation of your Studio Shed.

Skip the hassle, save money, and start enjoying the extra space you know you need sooner than you ever thought possible. Start building.
