along the front its 9m x 7m wide, it tapers along the boundry wall and because of this its 7m at the back
still huge, oh and its got an upstairs
trench is for the 4" soild waste pipe, cold water supply and armoured electric cable, an underground access tunnel sounds better though
only designed it to fit 2 cars with tond of space around them to work, could probably fit a few in , havnt really did the maths to find out
hopefully next year my
