As part of my Dux Rohirrim project, this is a Sarissa model, Timber A Frame, from their 28mm Dark Ages range. I wanted a few buildings to be tempting targets for orc raiders and this has a useful generic feel without taking up too large a footprint on the table.
I am crowdsourcing some advice on the thatch whether to paint it or leave it alone.
The Sarissa kit comes with a plain wood roof, scored to suggest planking, but gives some suggestions for thatch. I stole an idea from a wargaming blogger (I wish I could remember who) on using terrycloth bath towels as thatch. I found a beige wash cloth at Walmart, chopped it into sections and glued them onto the roof.
This reconstruction of a Dark Ages hut from a dig in the Cheviots in the UK looks a little more brown to my eye, but truth be told, a google search of dark ages thatched roofs shows a variety of colours and textures.
Blessings to your buildings!
