Carport for IP - Timber or Metal?

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?

 

Aluminium

 

DIY or (from those prices) paying for install?

Check out Stratco, they can supply DIY kits with plans for council etc, or have someone come out for measure & quote install, show you what it will look like on a laptop.

Pretty easy to DIY, as your only coming out ~3.8 from facia you should get away with tek screws via internal brackets (rather than weld), bolt posts to the slab (unless it's a dig and rapid set)

I've thrown them up with patio tube and trimdek

 

I would say it depends on how accomodating you are to the local termites...
The cost is surprisingly high, isn't it? If timber suits the house and there are no other issues, I would consider it but imagine it's nowhere near as sturdy as aluminium.

 

6 of 1 and 1/2 dozen of another. Coin toss.
