I also chose the IKEA route and can't recommend it highly enough! My kitchen is approx. 13sqm and I bought all units, doors, legs, handles etc. for £670 (four years ago), finished it off with a solid beech worktop from Woodworkers (also very good service) - by the time I added flooring, fittings and finishes the whole thing was completed for under €3k. Most quotes that I received from other suppliers were €3k+ to start off with.
