About 70% of the land in the UK will never be built on for various reasons. This leaves 30%. That 30% contains all the towns, cities, suburbs, and various industrial estates, ports, airports and so on. The actual amount of land vaguely available for projects of any sort is rather small, and those projects face heavy headwinds in terms of planning permissions, NIMBYs, and other interests expressed often by people living nowhere near the land in question.

You don't even need lobbies. Anyone who owns a house isn't bothered by this, unless they are particularly fair-minded. It only affects people who don't own their own home, which is a much smaller voting group.
