Rough Estimate of Costs

[White Fox]

I want to build a 'pergola' roof attached to my house. Permits, drawings etc aside and given the details below can anyone give me a rough esitmate as to what the cost to have it built would be ?

12m long (ridge down the centre), 4m wide, 22.5 roof slope, probably 5 posts down the non-house side & colourbond roofing. We're going to pave underneath.

Thanks in advance.

That's not a pergola...that's a verandah but that's nitpicking. This'll be hard without a diagram of what you intend. Also you don't say whether it's a DIY effort or a builder job....nor do you indicate your preferred framing material - sodtwood (eg oregon), hardwood or steel. All have different design criteria and different pricing.

To get an idea on what the materials might cost then I'd suggest you start at www.buybuildingsupplies.com.au

Otherwise ask Spanline for a quote........won't cost you anything.

If you wanted to do it as a Spanline Patio Roof it would be approx. $15,000 supplied and installed. If you bought the materials and did it yourself it would cost approx $10,000 to $11,000 for materials.

Thank you Barry, thats very helpful at this stage.

SBD, I thought saying 'to have it built' was fairly clear that it wasnt going to be a DIY effort. I also put 'pergola' in 'inverted brackets' because I'm aware it's not strictly a 'pergola'.

There's alot of nitpicking that goes on within this forum and I really cant understand why. The inexperienced amongst us wouldn't be asking questions if we could knock things up with one hand tied behind our backs so there's no need for 'experts' to come out and rubbish our ideas and questions.

A couple of years ago my Daughter wanted a patio 9m x 4.5m, pitched roof with hipped ends, all steel framed, colourbond roof. She got a price from one mob for $6,000. I said to her if you want to throw your money away go ahead and use them or I'll build it for under $2,000 (that was a figure off the top of my head). Well she choose me... total cost $2,300. Materials - 4 posts 100x100x2.5mm, beam 150x50x3mm, 4 trusses made from patio tube 75x38x1.6mm all welded, purlins from patio tube with all ends capped (welded), plus rafter brackets, concrete, screws, bolts, paint etc.

WF,
to be fair, I don't think SBD was rubbishing your ideas or questions. He did add that saying the roof wasn't a pergola, strictly speaking, was being nitpicking. I've answered more than a few building/renovating type questions and will correct peoples use of terminology. This isn't nitpicking, it's ensuring clear concise communication. Other people read posts besides the original question asker and it doesn't help them in the least if they think that architraves are cornices or vice-versa. Also I don't know if there's been any editing but I don't see any mention of 'to have it built', only "I want to build a 'pergola' roof".

SBD is quite correct (and more helpful than you might realise) in his post. If you ask how much a new car might cost without specifying size, type, brand etc then no one can really hope to give you any form of meaningful answer. Anything from about $10K to $100K++. Call that nit picking if you will, I call it communication.

Come on Mick, you're supposed to know exactly what the guy wants from a two sentence post. What's wrong with you?

[speedy]

Come on you guys, I know exactly what he wants, a big roofy, shedy, thing next to the house 12 metres long.

Thanks for your support, lads. WF, I wasn't trying to be nitpicking - I was simply trying to get a bead on what it was you wanted. It's very difficult to visualise a concept whilst it remains stuck in someone elses head - and getting the terminology right is just one part of imparting information. When we have this info then we can really really help rather than simply giving you guesswork.

It's a simple rule........a cost estimate is only as good as the original specification.

But Barry's guesstimate is a good place to start.....

That quote was based on current pricing from one of Australia's biggest Spanline franchises at full retail pricing. Bear in mind that these can vary from franchise to franchise. This was put through a spreadsheet that actually designs as well as prices the Patio cover based on the sizes you quoted.

It also allowed for a box gutter between the house and the Patio cover as the standard gutter is not sufficient to carry both the roof water as well as the Patio cover water.

It also allowed for downpipes to the ground and footings for the posts as you said you were going to lay pavers and they aren't any good to fix posts to.

It was designed to N1 which is metropoliton. If you are on the edge of town in a rural setting it would have to be based on N2 or N3 which would possibly add to the cost.

Also site conditions can effect the price as well.
