There is a lot of wasted space under 'Desk Booking' - this could be utilised with a biweekly calendar populated with 2 colours (remote/in office); personally I prefer the visual aspect so would prefer this with the option to select and book rather than selecting the date which I don't usually know off by heart. There could also be an outlook add-in which automatically populates the calendar with an 'all day' event or 'London Desk Booking' which is what I would do manually anyway
