I'm not sure how I became a guest all of a sudden, but hey ho No. 2a is a semi-detached, sharing that status with a house in Lawson Drive, and as the 'a' might suggest, sits immediately adjacent to No. 2. It's obviously been built when Lawson Drive was constructed and maybe because of the awkward angle at which it sits, the Council have decided to make it an add-on to Clyde Terrace.
PT is 2a still there? In my head, I always thought it might of been a flat, but you obviously know the street well. Thank you for that!
The dead before us, are as equally important as the living.
It's definitely a semi detached house. If you look closely at the picture below and zoom in you'll clearly see "2A" on what looks like a white post box to the right of the front door.
