What flooring to use? Original thought, use tiles, however the cost of tiling over existing floorboards isn't cheap. Polish the floorboards, however the previous owner stuck the tiles straight onto the floor. Some places look ok, others don't. In addition, we came across what appears to be a large chunk on concrete. It is where the kitchen is going, however its 2.6m wide 1.3m deep. Kitchen cabinets are 580mm deep. Laying bamboo flooring. Not sure how much this will cost. Any suggestions?
