Vict' /Edw' (1837-1910) Terrace,Windmill Hill
An architect inspired Victorian terrace retrofit with minimal reliance on gas and electricity, thanks to solar technology. Incorporating air-tightness and insulation throughout for a tightly sealed, yet breathable envelope.

This Victorian terrace in Windmill Hill uses a range of technologies and building techniques to minimise gas and electricity consumption. It has a total floor area of 97.5m2 including three bedrooms.
The house is a product of contemporary vision and architectural knowledge and stands out as an example of great achievement. A timber frame construction enhances the heat properties of the home.
Carlton views this as an ongoing project and recently extended the house to gain more functional kitchen, dining space. The expansion re-used the bi-fold doors and incorporated background ventilators for year-round fresh air supply, instead of using trickle vents in the windows. Timber from the deck and wood store were re-purposed to build a garden shed.
Following a thermal heat loss survey from the CHEESE Project. Carlton is planning to put right the issues highlighted by survey sometime before the next winter.
Most of its heat comes from passive solar gain and is maintained using natural heat retention methods and household electricity consumption is kept down to 1800 KWhs per year.
Living in a Victorian terrace comes with its problems. Carlton and his wife have been in the house for 10 years and have been gradually making ongoing improvements.
The pair wanted a more contemporary feel to their home, so with Carlton’s experience in architecture, he set in place a plan to reconstruct the frame of the building.
The couple deliberately set out to incorporate the optimum number of technologies on site.
They wanted to learn from a broader range of feedback, informing them of how well their home responds to different technologies. “It must be recognised that much of the measures installed here aren’t the result of extensive contracting,” Carlton proudly claimed, “doing much of the work ourselves, we are really pleased with how contemporary our house feels.”
With 2 children to work around it has been a balancing act to make improvements while avoiding too much disruption. A demonstration of no matter how disruptive the changes might be, doing it yourself can be a greatly rewarding experience.
Doing much of the work ourselves, we are really pleased with how contemporary our house feels.Homeowner, 2015

How this house performs
The chart for 2019 case studies shows the household’s annual energy consumption and generation data compared to Ofgem’s Typical Domestic Consumption Values - industry standard values for the annual gas and electricity usage of a typical domestic consumer. For more info click here.
The home now uses minimal gas to charge the thermal store – 4000 kwh annually, compared to the average UK household consumption of 12,000kWh.*
The latest EPC assessment shows that it has reached the full potential for energy efficiency performance.
*based on Ofgem’s Typical Domestic Consumption Values - industry standard values for the annual gas and electricity usage of a typical domestic consumer.
Carlton foresees a future project involving the acquisition of a plot of land and building their next home to Passivhaus standard.
A well-insulated, air-tight ‘envelope’ of a home can really make a difference to the heating, we’ve been sealing wherever we can as we go along.
