I've been granted planning to construct the house I’ve always wanted to live in. It's a two story curved roof barn with a full height living area at one end. With the front being faced in the limestone from the little old cottage it's replacing.
Not being an architect or anything close I simply did all my sketches and passed them through to the engineer responsible for getting it through the planning stages.
Now it has come to the construction phase and this engineer has spec'd a complete Steel Sub structure to support the roof with traditional Cavity walls in between the Steel uprights, and to be completely honest I feel it's overkill and unnecessary
The building is 17.8 Wide x 10.4m deep with the Highest point of the curved roof being 7.4m and the height of the point where the roof meets the external walls is 6.1m.
The steel sub structure proposed Breaks the building into 4 bays making for two uprights and a curved beam at 5 different points and 2 additional up rights at each gable. Each of these 14 up rights has it’s own pad foundation. Once these pads are poured it is then proposed to pour the shallower strip foundations between the upright locations.
Am I mad or does this seem ridicules to anyone else. Surely the curved beams could sit on capped traditional cavity walls. The roofing material will probably end up as crimped zinc or a soft torched-on finish(not decided yet, I need to get out and research). None the less a roof of this nature I would imagine would not have the same weight or load bearing of a traditional pitched, slated or tiled roof; which we sit on walls all over the place
Some neutral advice would be much appreciated, be it to prove my insanity or not...
