Extension Design Nightmare

Hi,

Looking for some advice please about a devastating situation regarding our extension design.

We found a home extension design firm 2 years ago who we entrusted with designing our extension. They are not architects but specialise in home extension design.

We gave a detailed brief of what we would like to achieve with an extension and gave a strict budget of £200K incl VAT this budget was reiterated throughout our many meetings with the company whilst the design was completed.

The designer came back with an amazing design and a projected spend of £198-213K incl VAT. So far so good.

However, it took 18months to seek Planning Permission due to the designers tardiness supplying drawings and a few issues with their design (they realised they hadn't left enough head height to get up the stairs initially!) but we were thrilled when it was granted first time round. They admitted to us that this was one of the biggest projects they'd undertaken but seemed really keen to manage the construction too. We duly handed over their design fee of £10K at this point and spent £2.5K on structural calculations to their engineer.

So next steps were to put the drawings out to construction firms to get quotes for the build. Here in lies the problem - out of 4 construction companies the cheapest quote was £310K + VAT and one was a trusted family friend.

Hence we can't afford the extension and have wasted 18 months and £10K on
a design that all of the builders said was unachievable with our original budget. I can't believe building costs have risen 50% in 18 months so feel that we have been mugged by the design company who have left us with a set of plans that do not fulfil our brief and planning permission for a home we cannot afford.

So the question is.... is there any comeback against the building design team or can they actually get £10K for a now useless set of plans that didn't fufil our brief?

I'd really appreciate any assistance in this matter as we're so upset that £10K of our life savings might as well have gone in the shredder like the useless plans. I should add we did not add or alter anything from their original plan that would have resulted in an increased price and they did not mention any increase from their projection over the 18 months.

Thanks for your help

it depends if you can prove that you actually briefed the design company to ensure the build costs would be within the specified budget and that they accepted that as part of the brief. Usually calculating building costs is the job of an ordinal survey. did your design firm offer to provide this service?

The naivety of the design company is apparent!

The designer should not have ploughed ahead with full planning permission for the design without going out for provisional tender.

In other words he should have done basic design drawings and put it out to several construction companies. If it came back over budget then the design should have been scaled down until it fitted the budget. Only then do you go for full planning drawings.

I would say that you would have a claim on the designers. Whether that is in contract or tort depends on what you agreed/signed. If nothing else they had a duty of care towards you and as a result of their breach you suffered a loss.

The comapny should have Professional Indemnity insurance which covers them for this sort of claim.

Problem is you will have to spend some more money to bring a claim.:confused:

If I were you I would go to the designers with your complaint that the supplied product wasn't to your brief and you want this to be resolved by way of design change.
Mention how the 3 estimators' quote shows that their design isn't achievable between £198-213K and even when asked to apply their cost planning knowledge/history the designs still wouldn't of been close to the brief 18 month ago.
If they're stupid enough not to listen or refuse to resolve your complaint you can take them to the civil court
To ensure you get back full cost of plans, structural calc expenses and all other costs and expenses you have incurred hire yourself a QS consultant. You may even get his fees back

N.B. Always have one of these before venturing on a build project with this size budget.

But remember, to take someone to court (not small claims) could set you back the best part of £10k. You might win but generally you do not get all your costs back, maybe 70%.

Small claims is different and not so much of a gamble. You could stand to lose maybe £100. If the claim is £5000 or more small claims is not an option.
