Being MDF they come flat packed. They also have lots of detail such as exposed brickwork, stone mouldings, battle damage etc so should paint up nicely.
But for me the really nice thing is that they come with bases that have pavement modelled in to give the buildings a more realistic look. The ruined models are £12.50 while the undamaged building is £13.50 both plus postage of course.
The building below is the one I requested dimensions for, they said the actual building is 200mm long, 100mm wide and just over 100mm tall. the pavement is 15mm wide, this makes the whole thing 230mm long by 130mm wide.
They also produce road sections to go with your buildings but there are no listings for these on eBay yet, although they are listed on their website.
To round things off they also do FoW bases and token sets. The token sets look good value at £2.00 plus postage for 35 tokens (five of each). They are unpainted though.
I intend to buy some of the buildings and possibly the token sets when funds allow (I've just spent £45 on roads & rivers from eBay, watch for a review soon) and I'll do a proper review when they arrive.
