Dolls house Furniture & Fittings

We are in the process of developing a range of interior and exterior furniture in the 2 primary scales 1:12, 1:24 and possibly 1:48  scales. The 1:48 scale is the same as "O" scale railway therefore some of the articles produced for railway are also transferable to miniature dolls house application.   We have produced 2 x 1:48 scale exterior bench seats which are interchangeable  between the two interests.   Window, door, fences, gates are also intended to be included in our range of products, again 1:48 doors and windows prepared for railway application are interchangeable.    Wall panel, weatherboard, board and batten, brick, stone etc.    Roofing tiles and slate are also possible future products.  Any ideas or requests for products are welcome.  We can produce hard to find products if we are advised or produce one-off items for a specific projects.
