It's an inherent problem in tourism: tourists want an "unspoiled" view, which means not building infrastructure for tourists or locals.
Building definitely is happening. See the Plan: https://www.edinburgh.gov.uk/downloads/file/25264/edinburgh-... - but of course you can't build just houses, you have to build roads and schools and waste disposal and public transport to go with them. The city has struggled with its tram project and the railways are at capacity.
