We have completed a total internal refurbishment to EnerPHit standard of this Semi-detached four bedroom Victorian house. The interior was completely stripped out leaving only the masonry exterior. A new load-bearding timber internal structure was constructed allowing the layout to be configured precisely to the client’s needs. The masonry envelope was then insulated with ICynene spray foam. This completely isolates the internal structure from the thermal envelope preventing thermal bridging from the heated interior to the outside. Moisture sensors have been installed between the brick and the insulation. Bow Tie Construction proposed this solution and we collaborated closely with the architects as part of the design process to develop an EnerPHit solution for masonry buildings that does not affect the external appearance and is cost-effective.
To the rear a new three storey extension was constructed to house a study, bathroom and garden access. The dual aspect study features exposed timber beams and built-in storage. The house features solar panels on the roof and a Tesla Powerwall battery. The lighting is all 24 volt LED. Its consumption is so low that the client’s battery charge has not dropped below 40% all winter. Although connected to the grid the client does not draw any electricity from it, quite an achievement for an urban building of this size.
The project has been shortlisted for Don’t Move, Improve! 2020 titled ‘Lawford Road’
