Extension Quotation

NKS2017

I have been quoted for an extension which works out as £2400m2.

Is this a reasonable price or is it excessive?

Depends on the spec - am sure our resident expert Doozer will be along to comment.

High spec £3k/sqm would not be unusual. Low spec the costs will be closer to £2k.

The proposed size is also relevant. The bigger the space, the lower then sq.m rate.

Prices per M2 are only a rough guide  and vary in different areas, as well as with issues like access to site etc. 
How much were you expecting to pay?

It’s 14.85m2 and the architect said builders charge between £900-1500 so expected it to be around £23k but been quoted £36k

£900? In what part of the country is this?

Sounds like a very out of touch architect.

I've got zero detail to go on, but £2,400 is pretty normal for a modest sized single storey extension.  

There's an architect that we have a relationship with and she asked me how much I'd quoted a client.  She was embarrassed because she had been telling people £1,000 a metre. 

In addition, material prices are rising at an exorbitant rate, which is a nightmare.  Timber prices are 50% up on last year and it's happening across all sorts of building materials, along with poor availability of all sorts of random items.   

Covid/Brexit/Brexit/Covid, there's definitely something going on and prices will not be going down.

I have a feeling this is a widely-held myth within the home architectural industry. My own quoted £1k-2k which makes me think it must be an accepted - albeit outdated - standard in these circles.

It is circa £1500 here in Cornwall for a standard spec (if there is such a thing these days with people building phenomenal houses here).  We have seen timber increase by 56% last year, another 12% since the start of this year and with supplier predictions of another 17-20% before the summer.  Timber prices have rocketed and it isn't stopping.  Crazy. 

If you DIY you can reduce some costs but you need to be sure you can do what is needed.

The whole square metre method is quite rudimentary.
I normally advise my clients £2,000/sqm but then I have a long list of exclusions which should also be considered:

• VAT
• Doors/windows
• Floor finishes
• Kitchen/utility supply and install
• Sanitaryware
• Refurbishment areas
