Before

Too cold in winter
Barely insulated, too many windows, all single glazed

Too hot in summer
Excessive sun-exposed glass

Energy usage was high
The heat pump worked very hard

No sheltered outdoor space
No respite from the wind

Sun glare in the living room
The remainder was gloomy

Noisy in summer
Sudden thermal expansion of the solid walls was loud

Deep shadowing on winter mornings
