Replace worktops on existing bases - one straight, one U shaped with cut out for sink. Create one new straight piece of worktop - not over cupboards (two walls, one end support required).
Ian did a complete refit of my kitchen, including removing polystyrene ceiling tiles; plasterboarding and skimming; fitting units, worktops and cooker; plumbing in sink unit, tiling walls and making good and painting other surfaces. He did a thorough and professional job, going to great lengths to find solutions to specific problems and to see that everything was completely to my satisfaction. Fixed price quote was adhered to in spite of the job probably taking much longer than expected.
