3rdSpace garden buildings are built to be enjoyed all year-round and have been used for a variety of applications, from garden rooms and garden offices, to creative spaces and studios. Our commitment to creating garden buildings of architectural integrity has resulted in a range of products that express functional, contemporary design; robust craftsmanship and attention to detail.


Standard specification and design features* include full-height low-E windows, a choice of cladding options and furniture-grade, birch plywood interior finishes. Our Modular range allows for further personalisation, with a range of additional options including green roof, internal and external shading, and flooring. The demountable nature of our buildings help to protect your investment, allowing you to relocate your garden room should you move.

* Specification and design features vary depending on model.


All 3rdSpace garden rooms are manufactured in the UK, from sustainable materials. This off-site prefabrication ensures that each building is precision-engineered and allows site assembly to take place in just a few days with the minimum of disruption.

Examples of how our customers have used our products to create their own perfect garden spaces can be found in the garden room and garden office sections of the website.

If you have any queries regarding the 3rdSpace range or would like to discuss your project, please get in touch.
