Roof

The roof was created using a few different shapes and moving them around in accordance with the reference planes. It proved quite a tricky structure to get right as the Guildhall slopes in one direction, making a slight twist in the roof.

I started by creating a long, thin box shape and placing it on a slant. This would be the front part of the roof. I then cloned this shape to create the back part of the roof. By converting these shapes into editable polys I was then able to modify them to achieve the twist. Using the reference planes as a guide, I began by slightly rotating the edges at one end of the building. With soft selection turned on, this gave the effect I was looking for and so I repeated it for the other part of the roof.

Once these two panels were in place, I created a long cylinder shape for the top of the roof. Again, because of the twist, this had to be converted into an editable poly so that the edges and vertices could be modified in order to follow the seam where the two roof panels met.

Next, the triangular-shaped side walls were created and, again as editable polys, moulded into the right shape by pulling around the vertices. Then finally, the chimney was created by simply lining up boxes with the reference planes.
