Architect: Christin Peglow @ pad Design Ltd
Structural Engineer: George Holland @ Element Structures
Project Value: £500,000
Duration: 13 months
Completion: May 2019

Project details:
Timber clad replacement dwelling within the Bristol and Bath Greenbelt and village of Chew Stoke providing a sustainable and contemporary family home that addresses its generous south facing garden and views with substantial glazing and patio doors on ground floor and a double cantilevered first floor, that relates in proportion to its local vernacular with rhythmical window pattern, low sills and an asymmetrical gable.


  • Constructed to Passivhaus standards with respect to insulation, airtightness and Mechanical Ventilation with Heat Recovery (MVHR)
  • Isoquick insulated raft reducing thermal bridging and providing thermal mass
  • Pre-fabricated timberframe in twin wall construction with Superglass 032 full fill and Beltermo woodfibre externally
  • Triple glazing
  • Solar PV tiles to south elevation with solar hot water heating, Tesla Powerwall and car charger
  • Green roofs to single storey elements

Our focus was on creating a sustainable and modern family home that connects both inside and outside spaces, catering to the client’s needs while meeting Building Regulations. The house incurs zero yearly energy costs, with £300 spent on winter electricity balanced by feed-in tariffs and export payments in summer, even providing a bonus for charging the electric car.

Client: Design Storey


‘Best Conversion’ at the 2021 Daily Telegraph Homebuilding and Renovating Awards

Project Description:

We were introduced to the client by Design Storey Architects, who we have previously worked with, due to our extensive experience providing Building Control services for listed buildings.

Working closely with the client during the early stages of the construction we were able to ensure that the buildings history and key features were retained, creating a stylish yet compliant renovation of the property.

The most challenging aspect of the project was achieving a satisfactory means of escape from the first floor, and the fire protection to the exposed floor joists using the latest innovations in passive fire protection. As well as the fire strategy the challenge of meeting energy conservation requirements on this listed building needed a creative yet practical approach. The finished product is a stunning transformation which retains the charm and character of the Old Flax Shop.
