The UK's favourite architectural show - Grand Designs is officially back on TV screens as Kevin McCloud travels around the UK meeting new ambitious individuals building their dream homes.

The Channel 4 show is now entering its 25th series, with previous episodes seeing everything from giant curved glass homes to mansions built out of clay and former water towers.

Now, more keen builders are ready to take on the task not for the faint-hearted as Kevin travels around the UK to see the new builds in Grand Designs.

Kicking off the newest series, are Sarah and Howard hoping to build their dream "floating home".

Worthing couple take on 'floating home' in Grand Designs

Designer Sarah and architect Howard have worked together for 30 years and now plan to take on what Kevin is calling one of Grand Design's most "ambitious self-building projects" yet.

The pair want to build a "sleek, angled, metallic floating home" on the estuary nearby Worthing by dismantling a Second World War landing craft.

The home is designed to look like a boat, to fit within the houseboat community, with the structure sitting on an "experimental prefabricated polystyrene slab to deal with high tides" according to the Radio Times.

To complete their Grand Design, the pair have a budget of £385,000 with a schedule of 18 months.

The pair plan to do as much of the work they can themselves, however, the build gets off to a very troublesome and slow start.

They are tasked with carefully removing a condemned D-Day landing craft on the plot before they can start the build while facing the constant tidal changes that create near disaster for the build. 

Grand Designs is on Channel 4 on Wednesday evenings at 9pm and is available to stream on All4.
