Extensions & Outbuildings
Planning and building sympathetic extensions, outbuildings, and garden rooms for listed and period properties using traditional materials.
Expanding a listed farmhouse, historic barn, or period cottage requires deep familiarity with traditional spatial proportions and physical craftsmanship. Rather than dropping an ill-fitting corporate box onto your home, Dave Heath carefully constructs sympathetic additions, outbuildings, garden rooms, and studios that match the existing structure's character and materials. Working step-by-step alongside your selected conservation architects, heritage consultants, and local planning officers, all construction work satisfies strict regulatory controls while remaining highly practical.
FAQs
Q1: What planning permission do I need to build an extension on a listed property? A: You will need both full planning permission and Listed Building Consent for any extension to a listed building. The permitted development rights that apply to unlisted houses do not apply to listed buildings. The planning application needs to demonstrate that the extension is sympathetic in scale, materials and design.
Q2: How do you ensure a new extension looks sympathetic to an old building? A: The key is materials, scale and detail. The extension does not need to look old, but it should not clash. We use traditional materials - lime mortar, reclaimed brick or stone if appropriate, timber windows - and ensure the proportions and roofline respect the original building.
Q3: Can you match traditional brickwork for a modern extension?A: Yes. I source handmade brick from specialist suppliers who produce them in traditional sizes and colours. For a seamless match I take samples from the existing brickwork to the supplier and select the closest match for colour, size, texture and bond pattern. The bond - Flemish, English, or stretcher - matters as much as the brick colour.
Q4: Do outbuildings on listed properties need Listed Building Consent? A: Usually yes, if the outbuilding is within the curtilage of the listed building - which in most cases it is. The curtilage (the grounds associated with the building) is part of the listing, not just the main house. Any new outbuilding, or significant alteration to an existing one, is likely to require both planning permission and Listed Building Consent.
Q5: Can you build a garden room or studio in the grounds of a listed property? A: Yes, but as above, Listed Building Consent is likely required for any outbuilding within the curtilage. The design should be sympathetic and materials appropriate - timber or traditional masonry, lime mortar, good detailing. Done well, a garden room or studio adds genuine value and sits comfortably alongside a period property.
