A bespoke summer house is a hand-built timber garden building designed specifically for your garden, your usage and your aesthetic. It's not a flat-pack kit dropped on paving slabs. The difference is visible immediately and structural over time. Ridgeline summer houses are framed on-site from C24 graded timber, set on proper insulated or screw-pile foundations, weatherproofed with breathable membranes, and clad in real timber with 25-year working life. Joinery — doors, windows, opening shutters — is fitted to fine tolerances, not the loose tolerances of a flat-pack. Inside, you can specify anything from a simple painted-board finish for a relaxed garden retreat to fully insulated and plastered interiors for year-round use. Power, lighting, heating and even a small kitchenette can all be designed in. Most summer houses fall within Permitted Development. We'll guide you through the size, height and siting limits on the free design visit. ### Best for Gardeners wanting a beautiful retreat at the bottom of the garden - Outdoor entertaining and 'garden bar' use - Reading rooms, art studios and quiet retreats - Hot tub shelters and pool houses - Period properties needing a sympathetic timber building ### When you'll need it - You want to enjoy your garden more — for longer in the year - Existing summer house is rotting, leaking or sagging - Hosting outdoors is limited by British weather - You want a beautiful focal point in the garden - An existing kit-built building has reached end-of-life The cost of getting it wrong ## Why kit summer houses look tired by year three. The garden building market is dominated by mass-produced kits. They photograph beautifully on day one and become firewood within a decade. ### Untreated timber Most kits use untreated softwood. It rots from the ground up within 5–10 years, often unseen until it's structurally compromised. ### Pad foundations Buildings sat on paving slabs sink unevenly, twisting frames and breaking door/window seals. ### Thin cladding & no breather membrane Single-skin tongue-and-groove with no membrane behind soaks up rain and starts rotting from inside. ### Loose joinery Kit doors and windows arrive with significant tolerance gaps that worsen with seasonal movement. Within a few years they jam shut or won't lock. ### Felt roofs that fail in 5–7 years Most kits use the cheapest roofing felt. EPDM rubber lasts 50 years for not much more cost. Our Process ## A clear, step-by-step system from first call to final handover. - 01 ### Free Design Visit We measure the garden, discuss style and use, and produce a sketch design. - 02 ### Design Sign-off & Quote Refined drawings, material specification and fixed itemised quotation. - 03 ### Foundations Insulated raft, screw-pile or properly engineered ground-level base depending on building size. - 04 ### Build Frame, weatherproof, clad, glaze, roof and finish — built in-situ on your site. - 05 ### Handover Decorated, lit and ready to use on handover day. The Benefits ## What you actually get when Ridgeline delivers your project. ### Built to your garden Designed around your space — not made to fit by trimming and packing on assembly day. ### Real foundations Insulated raft or screw-pile base — no sinking, no twisting, no leaking joints. ### Real timber, real lifespan Treated structural timber with cedar, larch or composite cladding — 25+ year working life. ### 3–6 week typical build Most bespoke summer houses complete in under 6 weeks from foundation start. ### Adds garden value A beautiful, properly built summer house is a feature on resale — kit buildings are usually a write-off. ### Truly turnkey Wired, lit, painted and ready to use — bring the cushions on day one. In detail ## Style, structure and the spec choices that decide longevity. Summer houses range from simple shingle-roofed retreats to fully glazed garden lounges. Here's how we approach the spec. ### Frame & structure C24 graded timber frame on insulated raft or screw-pile foundations. Properly tied and braced — not just nailed. ### Cladding options Western Red Cedar, Siberian Larch, painted shiplap, or composite cladding. All on a ventilated rainscreen. ### Roofing EPDM rubber for flat or low-pitch roofs (50-year warranty); cedar shingles or fibre-cement slates for pitched designs. ### Joinery & glazing Hand-fitted timber doors and windows or double-glazed aluminium where you want maximum daylight and minimum maintenance. ### Insulation & year-round use If you want to use it 12 months a year, we insulate floor, walls and roof to garden-room standard. Otherwise a 'summer use' spec keeps cost down. ### Power, lighting & heating Dedicated armoured supply, internal and external lighting, heating where required. All Part P certified.
