Talking of larders, as we were, I was pointed at this scheme we did at Lucas Hickman Smith a few years ago for a sustainability enthusiast down near Halesworth.
The house has a traditional larder tucked in under the stairs. It was insulated from the rest of the house (the thicker internal wall) and though the drawing doesn’t quite capture it, the insulation in the external wall was omitted – quite a tricky detail! It had an old-fashioned mesh window and a stone floor to act as a ‘thermal flywheel’, evening out the diurnal temperature range.
