Is this the ugliest Grand Designs house ever?

A deep sea diver and his wife spent £450,000 building their dream family home almost entirely out of concrete.

Without brick or mortar in sight, Adrian and Megan Corrigall spent 18 months creating the pioneering four-bedroom property in Lewes, East Sussex, as seen on tonight's episode of Channel 4's Grand Designs.

After paying £500,000 for the plot, the couple razed the existing property to the ground and set aside an additional budget of between £300,000 and £400,000 to build the bungalow out of a cutting-edge concrete.

However they quickly run into unexpected costs and end up spending £50,000 over budget, forcing Adrian to head off-shore on deep sea diving jobs to bring in extra cash.

'We have had an absolute nightmare, we’ve got credit cards and god knows what up to our eyeballs,' Megan admits in one desperate moment. 'We were pushed into this position where we couldn’t do anything.'

Despite the problems, the couple stand by their decision and defend their property when it is compared to a 'car park' and an 'electricity substation' by presenter Kevin McCloud, who was initially sceptical of whether it would be 'homely enough'.
