House Building Server Map - Max Room for buildings (40)

Ths is one of my first maps so please don't slate me over it. I've been told its great and it IS a MASSIVE map, so it could act as a potential server.

Districts -
1) Main Train station - seen top right. contains 5 stating tracks (one is seen which stretches for over 2 km. there are three stations on route of this track (potential building areas).
2) House - Small random house next to Train Station. Provides a route to the MASTERPIECE.
3) HUGE Building area (about 1/3 seen in bottom right). Also a building on far side of it (wouldn't fit on screen shot)
4) THE MASTERPIECE - MASSIVE UNDERGROUND BUILDING AREA. Directly underneath the flat area seen in bottom right. About twice as big and VERY tall. has lava lighting built into walls and i love it down there.
5) The shuttles - seen in glass tubes. provide quick transport around the map
6)Conservatory (far left) - at the end of one shuttle and is a route down to the MASTERPIECE.
