The hit Channel 4 architectural show Grand Designs sees ambitious individuals build their dream family home, and this week's episode is no different.

In the first week of the new series, Manchester couple Colin and Adele learned the hard truths and the dos and don'ts of building their curved glass mansion.

The second in the series saw Tunbridge Wells-based Kate and Rob replace their rundown post-war prefab home that stood the ages and lasted a lot longer than expected.

After that Canterbury-based couple, Dorran and Vereuschka build an underground hidden home but trouble arose for the pair after they parted ways with their contractor and took on the project themselves.

They were then followed by Hertfordshire couple Matthew and Davidzo who built an Australian and Zimbabwean-inspired home on the sloping hills of the Chess Valley.

Derbyshire couple Mike and Sarah sought to create a medieval longhouse-inspired build in the week after with hopes to bring the family together.

Bedfordshire couple, John and Helen were next as they built a modernist pavilion with a £1.3 million budget to create a comfortable and accessible life for the pair. 

Whilst last week saw London-based Corinne create an impressive yet awkward extension as she looked for a fresh start following a few difficult years. 

Now, this week sees the return of the much-anticipated re-visit of the North Devon couple who hope to build an impressive lighthouse-inspired home. 

Grand Designs visits troubled North Devon Lighthouse inspired build

Back in 2012, North Devon couple Edward and Hazel started an ambitious build inspired by a lighthouse overlooking the North Devon coast. 

The couple's aim was to create a stunning new home with five to eight bedrooms, five bathrooms, an infinity pool, and a white lighthouse tower for the family of four.

However, the project quickly met a boast of problems as Edward was left with around £4 million in debt making him near bankruptcy and seeing the couple later get divorced. 

Now after a decade since the build first began, Grand Designs returns to the plot to see how far the house has come and if anything has been salvaged from the disastrous project. 

You can watch Grand Designs at 9pm tonight on Channel 4 and All 4.
