If you have the time to plan for it do as I do (and am still doing) and build a house with mostly preloved items. I actually bought a steel house frame on Ebay that was a display home pulled down. It is of commerical quality so the house will be built to last. I also go to auctions and garage sales. I aim to spend no more than 10% of the retail price on home fittings. This way I can enjoy stone benches and water features and towel warming rails that I otherwise would not be able to afford at this stage. It is a long process but very rewarding as you see it all come together to fit in with your vision. Just be careful and find out your local building codes. Where I live I need to have a safety certificate for glass in windows. I can get around it if the second hand windows I buy can be tracked down to the manufacturer so a new certificate can be issued or as a last resort you can replace the glass. Sometimes like in the case of bifold doors, it can be worth doing that. You will get a safety certificate from the new glass installer.
