Guru's and Grasshoppers

Yesterday we had a 'Guru's & Grasshopper's session with the second years. I found the session was really useful and the feedback that I got was really useful.
I was stuck slightly in a rut, not sure if I should continue with the time aspect of the project or move on with the sinks/bathrooms idea. I decided after feedback and discussion that I would drop the time aspect as it wasn't exciting me enough, and I couldn't see how to develop it further. I decided to start to concentrate on bathrooms and using a grid style layout. I also decided it would be important to get enough variety, to keep the project interesting.
