The two ways into the main lecture room are both on the wall furthest from the main entrance. They’re not visible as you enter the building; go to the far wall and turn either left or right to see one. This pic is of the left-hand door.
The floor is flat, and the chairs can be rearranged – it’s not fixed seating.
(On the day I was taking photos, we couldn’t get in to the lecture room, as it was locked.)
None of the disabled parking is absolutely next to the front door of the building. The two closest spaces I’ve seen are two individual ones at the base of the tower, behind the ESLC building. Next closest is the little Blue Badge car park near the Maths building. There is also free parking for Blue Badge holders on the main car park.
To park in any of the reserved spaces, you will need either an actual Blue Badge, or a permit from the University.
So, depending on how you’re travelling and whether you need a Blue Badge parking space, here are some various options of routes and information:
From the city centre on a bus which stops outside North Entrance, or if coming that way by bike or walking: Come onto campus at the North Entrance. Then, for a shortcut which cars can’t use, take the “back way in” to Science City, past Cripps Computing Centre.
Note: These are not the only ways onto campus! If you’re coming from Beeston, or cycling from town along Castle Boulevard, other routes may be quicker or easier for you. I’ve concentrated here on routes which make sense coming from town, as that’ll be what most newcomers need.
