Costs of each part of a self build

[Bournbrook]

Hi all

 

im sure something already exists on this, but I’m struggling to find it, so if someone could point me in the right direction, I’d be grateful. 
 

I am just doing some budgeting and want to work out what extra costs I can expect beyond the actual build costs and architect fees? We’d be looking at building a 1.5 storey of about 150sqm in the South East. 
 

thanks

Are you thinking of SPONS

180 quid may seem a lot, but if your build is costing £2000/m², it is the same cost as a very small wastepaper bin.

get it properly QS'd by someone like estimators.com and then add 20% contingency. It's what the banks would use if they were funding the build so not far off.

 

An cheap  cost would be £2500 m2 / £375k nicer finish/difficult build £3500 m2 £525k

• phone calls
• trips to the BM
• networking
• administration 
• the costs associated with the mental stress of building
• research time
• the stress imposed on partnerships
• the effect of the build on children
• the time wasted on Build Hub 😉

Sorry I think I’ve actually phrased this wrong. We are looking to use a main contractor, so really I mean costs beyond building the house (costs to main contractor for materials and labour). 
 

Things like, SE, QS, surveys, warranties etc etc

All the things that are made from paper and ink.

@ToughButterCup stopped posting up what his professional fees and indemnity policies were costing him when I pointed out they had reach the price of my house.

So true

You should be looking at about 10% (of construction cost + VAT) total professional and finance fees for a typical build.

It’s worth costing your utility connections if you haven’t done so 

We we’re very lucky on our previous build Coming around 3k for all three

Yes I would certainly encourage you to get estimates from the service suppliers sooner than later - can be done online and can be as little as £3k depending upon the site and connections available etc.  Beyond that, things like warranties - depends upon your intentions - are you going to stay in there for longer than 10 years? If so there is an arguement not to bother. Otherwise I guess you could be looking at £4k plus - again it may depend on how the build is being finanaced. Ground surveys about £2k I guess.

 

Take a look at my blog - there are some costing on there for a 165sq m 1.5 house but be mindful the costs are 5 years old now so allow some uplift.

 

I hope this helps.
