Good wood - this beautiful house was designed to blend into the hillside in Carmel valley, California, and they’ve done a great job of it. A grand central staircase runs through the heart of the house and it’s surrounded by lovely open spaces giving it an airy feel.

Good wood - I only need one image to show the epic beauty that is this staircase in the Aarhus Town Hall by Arne Jacobsen and Erik Møller. The floors are lined in bog oak (oak from thousand year-old tress dug out of swamps and dried very slowly). This wood is nearly fossilised and extremely strong and heavy, featuring a deep chocolate colour that gives this interior it’s seductive, enduring quality. Stunning.
