Hightrees House is an odd place. What was clearly quite a luxury development overlooking a pretty part of Clapham Common has had an ugly storey added to it in recent times, complete with incongruous black weather boarding at the junction between new and old. The classic move of retracting the white balcony fronts floor by floor is not finessed - the balconies just get shorter with the same windows behind them. It almost feels like a fake! But the gardener has done well in the rear courtyard, and the big bay windows are original and spectacular. The usual lamp-post detail is there too...
