I like the idea of a freestanding kitchen for many reasons – easy to install, can be cheaper (but not always) than an installed kitchen and you can take it with you. Also you could get by with a temporary freestanding kitchen while saving up for a hi spec one.
Here are some free standing kitchens –
Mobile kitchen from Bulthaup
Free standing kitchen from John Lewis
Free standing units from Ikea
Shelving from Howards Storage World
or you could mix and match with second hand items like this unit from Gumtree for 130 euro –
