Raising the roof 1

The cutaway sections of walls and roof provide great views of the interior of the model, and for this to work, only a small part of the upper floor section remains intact - the landing, at the head of the stairs and the section at the front of the shop, under the intersecting gable roof area.

The horizontal section of the first floor ceiling was fabricated from 0.8mm thick Birch ply and stained to match all other interior wall cladding. Small sections of balsa wood were cut and glued to recreate the rafters.

The whole roof was clad, inside with 6mm wide planked cladding, whilst the outer surface was clad with plain plywood sheet to act as a substrate for the later addition of the roofing slates.

With so many windows and other apertures, it must be assumed that virtually every part of the interior will be viewable, so all surfaces were decorated and made presentable.

The outer surface of the roof however would be covered by slates, so an overall black coat of paint would be sufficient preparation.

Although I was very keen to get started on adding the roof tiles, it became clear that the exterior wall should be painted first. This is something I have been putting of for a few weeks as I didn't want the decorative finish to become damaged through repeated handling. Now seems to be the time. But first, a few little dings and flaw needed filling and some details such as the door and window arches still needed defining.

After the brick textures were completed, the barge boards were fabricated from white HIPS plastic strip sheet material and we were ready to start fixing the slates.

A4 sheets of 0.5mm thick black HIPS plastic sheets were cut into strips and then partially cut into individual slate shapes. A certain amount on distressing was applied to the edges to replicate the texture of natural slate. When fixed in alternate overlapping layers the effect becomes quite realistic.

The rear face of the roof is just one, plain overall area and was fairly straightforward to clad in plastic slates.

The main part of the roof featuring the intersecting gables is another issue. At the intersections, it is necessary to introduce lead flashing to form watertight valleys. This was achieve with real 0.5mm thick lead, a specialist material supplied by 4D Model shop in London. This material is so flexible that is will form around all sorts of shapes and angles.
