Grand Designs: Couple go over budget in snail-like house

A couple with a passion for nature spent £800,000 creating a curving, snake-like home that nestles in the rolling hills of the English countryside.

Stephen and Elizabeth Tetlow dreamed of building a home that resembled a fossil shell, and that reflected their respective passions – his work as an engineer and Elizabeth’s as a horticulturist.

Having planned to spend 12 months and £600,000 on their ambitious project, the couple ultimately went £200,000 over-budget, and came in a whole year behind schedule.  

Most of the work was their own design, as Stephen drew up the plans himself with the help of a single architect, and the couple spent nine months attaching the distinctive roof panels to the building themselves – all by hand. 

The end result is a striking, curved building – which Grand Designs presenter Kevin McCloud likened to a snake – with breathtaking views over the Blackdown Hills where Somerset borders Devon.

The couple’s new home features in this week’s episode of Grand Designs on Channel 4.

Stephen, who is the chief executive of the Institution of Mechanical Engineers, said the idea for the unique home came to him when he saw a spiral ammonite shell on a desk.

He explained: ‘We were having a discussion with an architect and on our kitchen table was an ammonite, a fossil. and the idea just grew from that discussion, it evolved from that. 

‘The general shape of the house is part of an ammonite sitting into the hill. This is not a place for a straight line piece of angular architecture.’

The couple already owned the plot as their existing house was there, but sold their London flat to help pay for the new home.

Because of the curved design of their new home the building work was very intricate, and the structure took far longer to erect than a regular, rectangular build.

The Tetlows ordered 33 solar panels from Wales, all of which were cut in bespoke shapes to create the detailed pattern on the roof.

To speed the process up the couple enlisted their son-in-law to help attach 4,600 roof panels, which they completed over a nine-month period between January and September.

Each panel had to be cut to an individual size to fit a pattern they’d painstakingly hand drawn on the roof.

The roof is curved, and demanded 38 pieces of bespoke glued laminated timber, which allowed it to be bent into the required shape.

Welcoming: A second guest bedroom was spacious and had a door that gave a picturesque view of the hills outside

The couple continued the non-linear theme inside the property, ordering a bespoke curved staircase that would fit with the structure of the home.

Horticulturist Elizabeth used clay to create imprints of plants she’d picked from the surrounding hills to decorate the walls of the home.

Host Kevin McCloud was taken aback by the building’s unique look, and told the couple: ‘I’m finding it hard to do my job here because normally I’m standing in buildings enthusing about them and waxing and being energetic about them. 

Finally finished: The couple were delighted with the end result and Stephen revealed that they had a home they created themselves

‘What this building is doing to me is kind of giving me a gentle shoulder rub, you know? I’m kind of being lulled by it almost. It’s absolutely great.’

Despite the project taking a year longer and £200,000 more than it expected, the couple are thrilled with their new home.

Stephen said: ‘I think the big difference is that somebody else bought that big beautiful house that we used to live in. 

‘We’re one of many generations who lived in it, we were the guardians for the next generation who will live in it but this is our house, we did this and I think that’s quite a big difference.’

Grand Designs airs tonight at 9pm on Channel 4.
