Looking to get some feedback about which material may be better for a tandem carport at an IP. Dimensions are 10m x 3.8m on a concrete drive. Attached at fascia, open three sides House is older 3 x 1, timber framed, cladded with concrete driveway. Quotes have come in between $5500 to $11,000 for metal......seems expensive with variations? Timber frame construction is around $4k for materials and labour...treated H3 timbers, colourbond and galvanised fasteners included. Outlook is 20yrs service from the H3 treated timbers and 30+ yrs for metal. Timber has to be painted to match the house colour plus repaint when house repainted - @10yrs. Metal would probably have a higher resale value than timber, but timber will suit the existing house. Easier repair with timber if tenants hit it with the car.......? Seems timber will be the value choice.....but what else am I missing?
