FAQs

Summer Houses questions β€” Portstewart

Can I use a summer house year-round?
Standard summer houses are single-skin uninsulated buildings β€” fine for warmer months but cold and damp in winter. For year-round use we offer insulated summer houses with double glazing, similar in spec to a garden room but with a more traditional aesthetic.
How much does a summer house cost in Portstewart?
Summer houses in Portstewart range from Β£2,500 for a basic 2.5x2.5m kit, up to Β£15,000+ for larger insulated builds with quality glazing and proper foundations. Bespoke high-spec builds reach Β£25,000+.
Do summer houses need foundations?
Yes β€” even smaller summer houses need a level, well-drained base. We typically install concrete pads, paving slab bases, or ground screws depending on size and ground conditions. Cheap installations skip foundations and the building suffers within 3-5 years.
Can I add electrics to a summer house?
Yes β€” we install Part-P compliant electrical supply for lighting, sockets and exterior plug points. Larger summer houses might justify a dedicated consumer unit; smaller ones can run from a fused spur off the main house.
What's the warranty on a summer house?
Materials usually carry 5-10 year manufacturer warranties. We offer a 10-year workmanship guarantee on our installation work β€” foundations, assembly, weatherproofing details and electrical work.
