What it is A permanent, fully insulated outdoor building specified as a self-contained guest room: dedicated power circuit, lighting, a heat source and glazing sized for the elevation. Floor, walls and roof are insulated for a Scottish winter. Who it's for Households with regular family staying over, clients who want more privacy for guests than a sofa-bed in the lounge, and families adding useable space rather than moving house. When you need it When the spare bedroom is already spoken for, when you want somewhere comfortable for family staying over, or when you'd like more useable footprint without a full extension. Why it matters A thin-wall summerhouse marketed as a guest room is cold, damp and unusable by November. A properly engineered garden annexe stays warm and dry year-round and holds its value for 20+ years. From £14,000 Fully finished Typical range £14k–£45k+ Spec dependent Average project ~£19,000 Recent builds Lead time 8–12 weeks Design to install On-site install ~7 days Standard build Prices vary with size, glazing, cladding and access. Electrics, lighting and heating are included as standard on every garden room. What goes wrong ## The cost of getting this wrong. Outdoor buildings sit outside in Scottish weather for 20+ years. The mistakes below are the ones we're most often called in to fix. ### Summerhouse spec sold as a guest room Thin-wall cabins feel fine in June and unusable by November. Condensation, cold floors and mould follow within one winter. We're regularly called in to strip out and replace builds mis-sold two years earlier. ### Undersized electrics Running heating, lighting and appliances off a single 13A extension lead trips breakers, damages equipment and, at worst, becomes a fire risk. Every Signature build is wired properly, on its own consumer unit feed. ### Poor base preparation A building sitting on paving slabs or a hastily poured slab twists, drops and pulls doors out of true within a season. Groundworks are the single biggest predictor of whether the building still opens and closes cleanly in ten years. How we work ## A process built for premium results. The same process runs on every project, from a £640 shed to a £45,000 garden room, so nothing slips and every customer knows what happens next. - 01 ### Enquiry & scoping call A 15-minute call with Ryan to understand how you'll use the annexe, your rough budget and your site. - 02 ### Free site survey & design consultation We visit, measure, check ground conditions and access, and sketch options that respect the garden and sight-lines from the house. - 03 ### Bespoke quotation A fully itemised quote covering building, base, electrics, heating, delivery and installation. No vague 'from' pricing. - 04 ### Manufacture & groundworks Your building is manufactured while our in-house team (or our long-term groundwork partners) prepare the base. - 05 ### Installation A standard build is installed on site in around seven days, including electrics through our qualified electrician. - 06 ### Handover & aftercare We walk you through the building and its heating. You then have direct contact with Ryan for anything that comes up. What you get ## The Signature difference. ### Year-round comfort Fully insulated floor, walls and roof, designed for Scottish weather. ### Heating & electrics included Dedicated circuit, lighting and a heat source in the price. ### ~7 day install Minimal disruption to the house. ### Bespoke sizing Around 90% of our builds are custom, sized and laid out to your site and use-case. ### Direct access to Ryan You deal with the owner, not a call centre. ### 20+ year build Engineered to hold its value and protect the investment long-term. In detail ## The specification, materials and options. ### Construction & insulation Every Signature garden annexe is built on a fully insulated timber-frame system. Floor, walls and roof are insulated as standard, with a breathable membrane and vapour control layer engineered for the Scottish climate. Internally we finish with plasterboard and skim as standard, so the room feels like part of your house rather than a shed with a light in it. ### Electrics, heating & connectivity All electrical work is completed by our qualified electrician, on a dedicated feed from your consumer unit. Every room includes lighting, sockets and a heat source, typically a wall-mounted electric radiator or an air-conditioning unit with heating mode. Data cabling for hard-wired internet, external lighting and exterior sockets are common add-ons and best specified at survey stage. ### Annexe & guest-room considerations We regularly build self-contained annexe-style rooms for family staying over. Layouts and glazing are worked through with you at survey stage so the room suits how it'll actually be used. ### Planning permission Many garden annexes fall under permitted development in Scotland, but any use as a fully independent dwelling has its own planning considerations. Restrictions also apply for listed buildings, conservation areas, and larger structures close to boundaries. We advise on your specific site as part of the design process and can submit a planning application on your behalf if one is needed. We won't quote for a build that we don't believe is compliant.
