Often old homes have been built using construction methods now deemed too expensive. There are many old homes built using full brick construction, hardwood or Oregon frames and rafters. Pitched roofs in lieu of trusses. Terra-cotta roof tiles. Hardwood strip floors. High ceilings with decorative ceiling linings or cornices. Many of these older houses are structurally very stable and suit extending onto or renovating rather than just knocking down and re-building an inferior product. In areas such as Pennant Hills, Turramurra, Hornsby, Five Dock there are many well built homes that would be much more practical to extendas these areas are full of structurally well built homes that just require some modern upgrades.
