So, I've finished scratching my head and begun cutting styrene on the new house.
I'm starting with the most difficult bit first, the northern wall which overlaps with the neighbouring house.
It took quite a bit of working out and on its own this stepped section looks very strange.
Offer it up into position though against number 22 and it begins to make sense.
The stepped section is necessary not just to help locate it in place but to help me work out where the wall at the front of the building is supposed to go.
There are three windows to hack into this side piece which is going to be interesting now that I can no longer lay it flat.
Hmm, tactical error there, I think...
