MA show revised ground plan?

10 x 6 shed flush to concrete edge in foreground. audiences waiting area on concrete foreground, in front of where shed to be, after entering through ground floor theatre building door. possibly put chain between shed and metal staircase to indicate no entry beyond here once audience gather.

a few points arising today giving rise to this revised plan now with measurements:

• LOCATION- big shed- decided to go with the idea of having the big shed flush to the top gravel that suited the future life of the sheds as theatre storage post my show at WCA- well, partly because of this but mostly through discussions with steve that as i want the sheds to look like found there, sharp edging them to the concrete suits this, and spacing them within the gravel would have not given this impression as functional storage shed needs easy ramp access and not stomping over gravel. this location will also mean that, with entrance at ground level its possible for the little shed to not be seen by the audience waiting to go into the big shed- meaning it will become an element of surprise more for the second part of the performance, hopefully.
  

• distances between sheds and gravel beyond little shed- this area is bigger than envisaged in shifting up the big shed towards the far end concrete, but maintaining the 15 ft between the two sheds to get a sharp focus in the big shed as a camera obscura. however, the schedule, weather permitting, is to complete big shed by thursday so friday can be spent making the big shed into a camera obscura and running angle of view and focal length tests before committing to the little sheds siting- may possibly switch the 15 and 10 feet gravel areas round on the plan. can the little shed be hidden from view until the second half of the performance?
  
• noise levels/access round the back of the shed space near to the fine art building end- spoke to lena today about signage she and anna are putting up- needs to be no entry/access/flow of people to minimise external noise directly around the sheds. this would also be to try to stop ruining the elements of surprise for those who hadn't seen the show yet by seeing me moving around outside the shed
• usher control- needs considering- where are they, what do they do? is the first time i appear when i walk into the shed after everyone is in there?
