In the above picture there are three buildings. Im interested in getting the top one. My concern is that its attached to the other two (roof forms a gutter with the wall) making it prone to water damage if not taken care properly.

The top side is also facing north west and the building on the right (one with the number 14), that is facing south will probably block all the sun (which is rare in the UK).

These things bother me a lot and under normal circumstances I wouldnt consider it, but it is relevant cheap, which is rare in the current house market, and in a good area. (I also have many questions around natural insulation, and making the building damp proof, but I will save those for a different thread)

Thoughts?

Apologies if this is not the right community but I couldnt find anything else as close as this one.
