Wow, thanks again all! I'm very humbled by the praise.

If I miss answering your question give me a nudge.
BTW, how did you paint the walls?
(this is for YIU too)
The walls are embossed plastic sheets. After I've primed them I give them a coat of Vallejo 'Dark Sand' for the mortar then I dry brush on a brown masonry paint from the local DIY shop. I dry brush at a 45 degree angle using a flat brush. When that's done I paint random bricks a darker brown. In all honesty the credit for the this technique should go to Overlord as I picked it up from him.
Is the built up front on the larger piece a more modern addition or would a facade like that be found on Victorian buildings as well?
Skrap, which bit do you mean? Sorry, I'm being a bit thick

.
What are you using for the drainpipe tops?
What's this other project then 
It's a Wills roofing set I picked up on E-bay, I'm sure with your intiative you'll knock something together in no time!

As for the other project; fisticuffs are brewing on the Red Planet so Her Majesty (Gawd bless 'er) has asked for a Mars Expeditionary Force to pop over there and shoot everyone.
Its really nice but the original thread doesn't mention what materials were used??
Apologies Lupus, the thread Gamer mac kindly posted and this one goes into a bit more detail:

Joras, have a look at page 4 on the link above. It's basically embossed plastic or wallpaper stuck on to cork. Keep the lengths short though or it warps!
Thanks again all for the kind comments. looking forward to building the next once once Mars has been laid to waste.
I will post some better pics soon.
