Looks like I need to say what i've got in mind for future releases.
Firstly, a barn and pigstys to go with the farmhouse model.
If there's enough interest, alternative roofs for the farmhouse.

British buildings planned-
Village pub
Garage
Post Office
Cottages
Farmhouse
Half-timbered buildings ( WotR onwards)
Bridge
Pillboxes

Small bits and pieces such as post boxes, dustbins, phone boxes etc

Any suggestions are very welcome
