Your body heat will keep warm is a stretch - not my idea of warm anyway 24C - maybe 16C which is chilly for most.

- londons_explore 2y agoNew builds require Roofs: 0.11 W/m²K. Walls: 0.18 W/m²K. Floors: 0.13 W/m²K. Assume 2024 houses are 7mx7mx5m high and terraced. So you have 70m² of wall, 49m² of roof and floor. Total 24.6 W/K. So, with the average UK electricity consumption (300 watts), plus the body heat of 3 people (300 watts) you have 600 watts of heating, which should keep that building 25 deg C above the outdoor temperature. The UK in winter normally averages about 5C, so you'd have an indoor temperature of 30C - plenty toasty. Obviously many buildings don't meet the required standards, people aren't home all day, there are air leaks, etc. But, for most buildings, heating is still not required most of the time.
- chongli 2y agoA free standing house at only 49 m^2? Is that typical in the UK? The US average size for single family homes was triple that back in the 1970’s. Today it’s more like 5 times that size.

Most people with lots of money buy an older house which is bigger, sometimes knocking down and rebuilding the same house if you want to modernize (in many areas you have to rebuild something the same size, shape and appearance).
