I am sitting in the Galleries Club South right now and everything just looks knackered. From the yellowing plastic tables and sideboards through to the wooden planks that have been worn beyond patina, the scuffing on the bottom of the doors and the rather poor state of the lavs, T5 just seems a bit knackered.

Given the high passenger flows, closure of one part of the terminal for refurbishment would cause tremendous lack of capacity in the facilities that remain open.

The terminal is 10 years old now and will be due a refresh at some point. How will BA and BAA renovate to make the place fit for the next 15 years?
