When upgrading a traditional property, homeowners often think they have to choose between improving how the house looks and improving how it performs. This recent project, completed in April 2026 in North West London, proves that you can drastically enhance both at the exact same time.
By installing a premium External Wall Insulation (EWI) system, we were able to completely revitalise the exterior of this terraced home while significantly boosting its energy efficiency.
When Visuals Meet Energy Efficiency
Before our team arrived, the property featured a dated, weathered exterior that offered very little in terms of thermal resistance. Heat was easily escaping through the solid walls during the colder months, while the summer sun would quickly overheat the interior.
The goal was to wrap the property in a highly efficient thermal blanket that would regulate indoor temperatures year-round, while simultaneously delivering a crisp, modern facade that elevates the entire street.
We applied an advanced EWI Pro system, utilising thick 90mm EPS boards to eliminate cold bridges. To finish, we applied a 1.5mm silicone render in the stunning shade of Diamond. The result is a breathtaking, clean white aesthetic that is fully weather-resistant, breathable, and incredibly easy to maintain.
