A garden room is usually detached from the house and located somewhere within the garden and almost always has a solid roof. Most garden rooms are used as workshops, studies, offices, storage areas or summer houses. A conservatory is typically joined to the house, is made primarily from windows and features a glazed roof. Conservatories can also be referred to as sun rooms.
Yes, our garden room extensions can be attached to your existing house and we will ensure that the design matches your homeโs existing design.
Most garden rooms are designed to last between 20 and 30 years. EHB uses the best materials (primarily French oak) to ensure our builds outlast this lifespan, and, a major benefit of building with oak timber frames is that it requires little to no maintenance.
In most cases, you wonโt need to apply for planning permission for garden rooms or buildings so long as they adhere to permitted development rules and guidelines. Our team actually works with an approved planning contractor, for more information on how we can help, please visit ourย planning permission page.
