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 show, on Channel 4, recently marked its 25th anniversary and aired a special Grand Designs episode to look back at some of its most iconic and challenging builds.

So far, the new series has seen a mixed bag of builds including one that nearly never was and another hailed as the best episode of Grand Designs ever.

In the first week, Zahid and Frezana turned an obsolete coastguard station into their dream home despite facing issues including planning permission.

They were followed by couple Zara and Giuliano, creating a 400-square-metre malthouse-inspired home of their dreams in the Lincolnshire Wolds.

Next was Kara and Jonny making a stone and zinc home that was completely accessible for wheelchair users to help Kara after a recent paralysis.

Last week Ara and Tony appeared on Grand Designs creating a home that was focused on health and wellbeing on a woodland clearing near Henley-on-Thames in Oxfordshire.

In the newest episode of the Channel 4 show, a new pair wants to make an abandoned water tower into a fun family home. 

Couple transform abounded water owner in new Grand Designs

Adam and Tassy have big plans to make an abandoned water tower, that stretches over 20 meters to a fun family home.

The property in Northamptonshire will have a radical design including a concrete interior, curved walls, slides, secret rooms, a fireman's pole and up in the tank, a swimming pool and a sky garden.

The couple hope to make their dream home but selling their terraced home and getting a mortgage to raise funds of £400,000 along with doing the work themselves.

But with two young children and a third child on the way, its easier said than done for Adam and Tassy.

The ambitious Grand Design gets off to a slow start when a steel reinforced floor takes forever to excavate, and they have to build a sound wall to reduce the hum from a nearby electricity substation.

The build only seems to get worse when they pour concrete that begins to leak through the walls and makes for a very wet build.

In a teaser for the new edition of Grand Designs, Tassy shares her fears for the project: "If it does go on too long, then we could grow to hate...or each other."

Grand Designs airs at 9pm on Channel 4 and All 4 every Wednesday.
