For 200 years, British homes were designed against the cold. The materials on my desk this morning are quietly redesigning them — for the heat.
Lime plaster. Travertine. Oak. Loose linen. Pale paint.
These look like decisions made for their beauty. However, they're thermal specifications dressed as tasteful options.
Lime plaster absorbs and releases heat across the day. Travertine acts as a small heat sink in south-facing rooms. Pale linen holds less heat than heavy velvet. The shift to lighter, slower, more mineral interiors that's defined the last few years isn't only a trend correction — it's a quiet response to summers our houses weren't built for. AS much as I love the dark and moody - where is its place moving forward?
Since the 40°C summer of 2022, the brief has been changing, but the houses haven't changed. The climate around them has.
The clients still asking about insulation are asking the wrong question. The more urgent conversation is shading. How are you coping with the heat?
