We're renovating our new house and it's been the intention all along to knock through the two reception rooms (12x12 and 14x12) into one long sitting room, as this is what we had in our last house. At the 11th hour we're now wondering if we are making a mistake and would get along better with two smaller, separate room. We already have a dining kitchen and workspace, so don't need room for these. What would you do?
