One of recent purchases was a couple of Sarissa Precision buildings, Victorian brick buildings, part of their Gaslamp Alley range. I had bought the terrace house and the terrace shop.
Here is the model from the Sarissa website.
The Sarissa Precision models are laser cut MDF and come plain. I do quite like how the 4Ground models come pre-coloured and though I have few Sarissa Old West buildings, as these are made from wood, the plain MDF look works okay.
The Gaslamp Alley models are brick, so I originally decided when I was going to put mine together, I would paint them later. So when I read the instructions that it was suggested to paint the window frames and doors (which were etched onto card) and the walls before gluing them together, it meant I had to think quickly about how to paint the walls. The instructions did advise about doing it sparingly, my concern was that would the paint cover the eteching.
I took some Vallejo (FoW) paint red brick colour (982 Cavalry Brown) and watered it down and used the same process I had used with the house which I had painted first.
For the roof and pavement I used 995 German Grey.
