For a garden room in Chelsea, the outdoor unit usually sits on a small stand behind the building. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
Garden offices used every day in Chelsea need cooling in summer and efficient heat in winter. Chelsea is about 2 miles from central London and falls within our London coverage. Postcode districts we cover here include SW3 and SW10.
