1: Unit 2a Wellington Lane, Bristol


Property type: New build timber frame house.

Project: Earthwise Construction was appointed as main contractor to carry our a full demolition of the old 1930s warehouse building and construction of a new timber frame three bedroom house, built to follow passive house methodology and certified to the AECB’s low energy silver standard.

Overview: Prior to the renovation works, the building comprised of a single storey warehouse building. The building was completely demolished, extensive ground works where undertaken, then a timber frame was erected using timber I beams/ I joists, this was then heavly insulated using a combination of mineral wool & wood fibre insulation with a lime render finish. The finished house comprised of three modest sized bedrooms to the ground floor, an en suite, main bathroom. A small rear garden was fitted in, to create a sense of light and openness to the rear bedrooms. The first floor comprised of a large open plan living room/dining room & kitchen, with a spacious roof terrace and glass floor to let light into the ground floor hallway.

Challenges: Having completed the next door building the issues of restricted access to the site continued to provided challenges.

As the building had a large complicated roof terrace and small garden to the rear, these areas provided plenty of technical challenges in terms of weather proofing and detailing with the wood fibre insulation.

Materials used: Engineered I joists/ I beams were used to minimise the need for steel beams. Mineral wool insulation & Wood fibre insulation was used throughout with composite triple glazed windows. Other materials include: engineered FSC bamboo flooring, natural stone tiles. A Paul Focus 200 Mechanical Ventilation with Heat Recovery (MVHR) system was fitted to provide ventilation requirements.
