Most garden rooms, wooden gazebos, and summer houses fall within permitted development rights, meaning planning permission isn't required. This depends on height, boundary distance, and total outbuilding coverage. Generally, structures under 2.5m (or 4m for pitched roofs) positioned at least 2m from boundaries qualify. Crown Pavilions provides comprehensive guidance, and where planning permission is necessary, we supply all technical drawings supporting applications.

Garden rooms are fully insulated with double-glazed windows and comprehensive electrical systems — designed for year-round use as offices, gyms, or living spaces. Summer houses traditionally feature lighter construction for warm-weather use, though Crown Pavilions offers insulated options. Summer houses embrace classic British aesthetics with Georgian windows and verandas, whilst garden rooms favour contemporary designs with extensive glazing.

Crown Pavilions' bespoke garden rooms typically range from £20,000 for compact garden offices to £60,000+ for larger, extensively specified structures. Cost factors include dimensions, insulation quality, glazing extent, electrical complexity, and finishes. We recommend viewing this as investment rather than expense — quality garden rooms add substantial property value whilst providing decades of use.

Our Western Red Cedar buildings require minimal maintenance. Cedar naturally resists rot, decay, and insects, ageing gracefully to a silver-grey patina without treatment. Annual maintenance includes cleaning gutters, checking seals, and inspecting roof coverings. Cedar can be treated with oils to maintain original colouring if preferred. Our 10-year structural guarantee covers construction integrity.
