So I am having my kitchen done in a couple of months and have an (almost) final plan. The room is just over 5m long by 4m at its widest and I'm hoping to get a table in front of the patio doors. I'm a bit concerned about having enough storage space. I need some wall units, but I'm not sure whether to have them on both walls or just one, and if I go for one which wall? Do you think it will be a bit cramped trying to wash up with cupboards above, both me and DH are v tall?
