Hi we are planning to do extension to our outdoor alfresco area which we hope will look something like the picture attached, and we are looking for recommendations for a concreter, tiler and builder who can do pergola extensions? We currently have a small concrete slab attached to house provided by builder but its too small, so want to add another concrete slab to this and have tiles (not timber decking) laid ontop. Also any tips/advice would be appreciated if anyone has done something similar and how much this cost you? Cheers
