This is a good example of a house where there are also other buildings to be included.
It is possible to include a detached garage or in this case a barn and piggery, however it does tend to reduce the scale. In this example the out buildings are some distance from the house and to avoid the model's base area becoming too large everything is done to a smaller scale.
This model's overall dimensions are approximately 33 x 26 x 10cm(tall) with the actual farm house being 26 x 5 x 8cm. This is a particularly long narrow shape as the house is several old buildings now joined as one house.
The larger the base area becomes the higher the risk of the flat area warping or cracking in the kiln.
