The Plough BACKGROUND
Originally a pub in a conservation area in the historical village of Steyning – The Plough – was converted into two semi detached properties in the 1980s. Our clients bought the larger property and wanted to add a loft conversion with an unusual barrel roof design, a side extension, pitch the roof of an existing extension and change the driveway while improving the ‘eco’ credentials of the house where they could. Bright Green Homes LLP worked with Cityzen Design LLP to renovate this conservation area house into a spectacular home while being sympathetic to the heritage of the building and area.
Period/Age of House: 1800s
No. Bedrooms: 4
No. other rooms: 5
No. of floors: 2
Floor Area: 130m2, which became 195m2 after the whole renovation
Cost: Refurbishment / Extension / Loft Conversion Work £180,000
Wall type: Mixed – solid/ cavity
The completely new slate roof of The Plough and the loft conversion was insulated with 100mm of PIR between the rafters and 70mm PIR under the rafters, all wrapped in an intelligent breathing membrane. U value: 0.13W/m2K
The existing flat roof extension was removed and pitched to include 150mm of PIR insulation, and two new large Velux windows to increase natural light. U value: 0.13W/m2KWhere space was extremely tight (in the head of the barrel roof) we used Spacetherm Aerogel blanket derived from Silica Gel and then wrapped with intelligent breathing membrane. The whole barrel roof was finished in a beautiful and hard wearing zinc covering. U value: 0.2W/m2K
The 1980s extension of the house was a cavity wall construction so we filled this with Eco-bead cavity wall insulation. U value: 0.36W/m2K
The front wall of the original solid masonry pub was insulated internally with 72.5mm of Phenolic Foam/ Plasterboard and a wood burning stove installed – along with sound insulation to the 4” thick party wall. U value: 0.27W/m2K
The Plough’s new extension is a timber frame construction with 150mm PIR between the studs, with ply over and then 60mm of wood fibre insulation rendered with a lime render to half the extension and timber cladding to the other half. U value: 0.18W/m2K
HEATING AND HOT WATER
New radiators throughout powered by a new Viessmann Vitodens 200W 26kW 95% efficient gas condensing storage combi boiler with weather compensation. This system allows for a small storage cylinder within the boiler to allow for two showers to run comfortably off of one boiler at the same time.
The whole house has benefited from a re-skim of plaster and also all new double glazed timber sash windows have had draught strips fitted.
Lighting throughout supplied with Low Energy 11W LED lights supplied by Lightfoot LED.
Our clients are doing the internal decorations themselves but externally we used Jotun Mur breathable water repellent paint. This nano-technology is micro porous but also dirt repellent.
