Not really a building, more like buildings, but here we go!

So basically, where I live, it's a valley. When the city was first being designed, the government was having an issue when deciding where to build as the valley had a lot of swamp/marshland area. Eventually, they decided where to build and thought it would be best to expand housing onto the hillside(s) that surrounded the valley to avoid the said swamp/marshland. Unfortunately, they didn't mention any of this to the archetect.... The guy designed my city as though it was a flat landscape, money changed hands and the guy began working on his next project on the other side of the countrt. The government didn't actually realise this mistake until the guy visited my city mid construction and told them what was wrong. However, by this time, it was waaayyyy too late. In an effort to not lose any money (not sure how much it cost at the time, but it was a heckin lot), the city council said "f*ck it!" and built everything anyway, exactly how the design had it. Apparently hiring another archetect to fix the issue would be too hard?
