A well-built timber structure transforms the front of a house and adds a sheltered outdoor space to enjoy. RPG Carpentry & Joinery designs and builds canopies, porches, pergolas and oak frame structures across Devon and Cornwall — engineered to shrug off coastal weather and lift your home's kerb appeal.
From a simple over-door canopy to a full oak-framed porch or a garden pergola, we deliver the complete structure: foundations and post fixings, the timber frame, roof structure and covering, and all the weatherproofing detail that keeps the rain out and the timber sound. We also handle the integration with your existing brickwork, render or stone so the new addition looks like it was always part of the house.
Over-door and window canopies that add shelter and character. Ideal for protecting front doors on exposed Devon and Cornwall properties from driving rain.
Open or enclosed porches with glazing, tiled or slate roofs and bespoke joinery, giving a sheltered entrance and valuable extra space at the threshold of your home.
Freestanding and lean-to pergolas to frame a patio, walkway or seating area, built to span comfortably and weather gracefully in the South West climate.
Traditional green oak framing with mortise-and-tenon joints and oak pegs — striking, long-lasting structures for porches, car ports and garden rooms.
Exposure is the defining challenge of building in Devon and Cornwall. Properties near the coast at Torquay, Plymouth and along the Cornish shoreline face salt-laden air and strong south-westerly winds, while rural homes on Dartmoor and Bodmin contend with persistent damp. We design every structure with that in mind, choosing durable timber, detailing the joints to shed water, and fixing posts above ground level to keep end-grain dry.
We start by understanding how the structure should sit against your home — the roof pitch, the line of the eaves, and the proportions that make a porch or canopy look balanced rather than bolted on. Where permitted development limits apply or a property is listed, we advise on planning considerations before any work begins.
Green and air-dried oak is the premium choice for frames and pergolas: immensely strong, naturally durable, and it weathers to a handsome silver-grey that suits stone and cob cottages beautifully. Pressure- treated softwood offers a more economical route for painted canopies and garden structures. Roof coverings range from natural slate and clay tiles that match local rooflines to lead and felt detailing for flat or low-pitch canopies.
Finishing options include clear UV-protective oils, traditional microporous paints, and translucent stains that let the grain show through. For coastal sites we recommend stainless-steel fixings throughout to prevent the staining and corrosion that galvanised steel can suffer in salty air.
The figures below are a guide for canopy, porch and pergola work across Devon and Cornwall, including materials and installation. Span, timber grade and roof type all affect the final cost, so we provide a fixed quote after visiting your property.

Durable species, stainless fixings and water-shedding detail so your structure survives the South West weather for decades.
A well-proportioned porch or canopy is one of the highest-impact improvements you can make to the front of a home.
We advise on permitted development and conservation rules so your project starts on the right footing.
Many porches and canopies fall under permitted development and do not need planning permission, provided the ground floor area does not exceed 3 square metres, no part is higher than 3 metres, and it is more than 2 metres from a boundary facing a road. Listed buildings and properties in conservation areas across Devon and Cornwall have stricter rules, so we always advise checking with your local authority first, and we can guide you through it.
A simple timber door canopy typically costs from £600 to £1,500 supplied and fitted. A full enclosed front porch ranges from £2,500 to £6,000 depending on size, glazing and roof type. A freestanding oak pergola usually falls between £1,500 and £5,000 according to span and the grade of timber. We provide a fixed written quote after a site visit.
Yes, when it is built correctly. We use durable species such as oak and pressure-treated softwood, raise posts off the ground on galvanised or stainless fixings to prevent rot, and apply weatherproof finishes suited to salt-laden coastal air. Air-dried oak in particular weathers to a silvery grey and lasts for decades in the Devon and Cornwall climate with minimal maintenance.
Yes. We design and build canopies, porches, pergolas and oak frame structures throughout Devon and Cornwall, including Plymouth, Exeter, Torquay, Barnstaple, Truro and Tavistock, plus coastal and rural properties in between where exposure to the weather makes quality construction especially important.
