East facing vs west facing flats

East facing vs west facing flats differ mainly in the daily sunlight they get, where east flats get mild morning sun with light levels between 5,000 and 10,000 lux, while west flats take in strong afternoon heat above 800 W/m² that makes AC bills 15% to 25% higher. An east home gives you calm, bright light from 06:30 to 11:30 without heating your living room. A west-facing home gets direct sun from 13:30 to 18:30, which heats concrete walls and keeps rooms hot late into the night.
Your daily routine and local climate should guide your final pick. East homes stay naturally cool by evening, which suits early risers who return from work after 18:00. West homes give you long daylight until sunset and stay naturally warmer during winter. Still, they often need thick curtains or sun-control films in the summer.
