A02 Full Size Spanman- Interim Submission Sierra Stathis 640338


Structural Concept The post & beam structure would provide structural rigidity for unconventional roof design, as well as strength to support overall weight of roof. It would also keep it secure in high winds. The beams would be quite large because the span across the width of the house is 5m. The rafters and battens would provide rigidity to ensure the roof stays square.


Materials & construction

Materials:

Construction:

-Timber rafters -Timber roof batterns -Timber plaster battens -Plaster for ceiling -Insulation -Galvanised box guttering -Post and rail steel beams to support roof -Double-glazed glass -colourbond corrugated roofing sheets

• A butterfly roof design structurally supported by steel post and beam support at valley and at each end. The posts would be bolted through flanges welded at the ends of the post and beams. • Rafters would run from the valley at right angles to post and beam supports and left exposed on the outside of the house. • Roof battens would be attached to rafters which the colourbond roofing would be screwed to. • Plaster battens would be fixed to the rafters on the inside, to which plaster would be fixed. • The ends of the roof would be left exposed without any capping.


Aesthetic design & function The butterfly roof consists of 2 asymmetrical angled roofs meeting in the middle of the room. The large overhanging roof on the south side is dramatic and can provide outdoor shelter if needed. Large double glazed windows on the north side and south sides create an open and airy feeling. While the valley in the centre is at 2.5m, not encroaching on the interior space.

On the north side there is only small overhanging, allowing for maximum winter sunlight inside to warm the house. The colourbond roof would be in a colour such as roof bark to match the surrounding bush.
