We are doing a pretty major reno which will involve reconfiguring half the house under the existing roofline. We currently have carpet/cork throughout but want to make the living areas and kitchen timber flooring. I think the existing floor under the carpet is pine - not sure what type. Our options are try to use existing pine floor, laminate floorboards or bamboo - hardwood is out of the budget. The house is brick veneer built in the 70's. We have a dog and two cats and are planning family in the not so distant future so I want it to hold up well - not sure pine would be up to the task. I've attached a picture of the floor from under the house. What would you do?
