In the latest episode of Grand Designs Kevin Mccloud meets a couple who have the idea to create a "floating home".
Howard and Sarah’s idea was to build a house on water, designed to adapt to rising tides and changing water levels. However, the reality of constructing such a unique structure came with several unexpected challenges.
"We want to create a home that's as fluid as the water around it," Howard explained, but Kevin McCloud pointed out, “This isn’t just about building a house. It’s about building something that can survive on water. And that is a very, very different challenge.”
The concept of a "floating home"

The idea behind the "floating home" was revolutionary. Howard and Sarah aimed to create a self-build that would rest on the surface of the water but remain perfectly stable despite the changing tides.
"It’s a house that floats, like a boat, but with all the comfort of a traditional home," Sarah said, describing the concept.
The house, which isn't the first Grand Designs floating house, was designed to sit on a large platform made of polystyrene slabs that would support the weight of the structure and keep it afloat. As the tide came in and out, the house was supposed to rise and fall gently with the water, much like a boat at dock, making it flood proof.
As construction began, it was clear that this wasn’t going to be an easy project. Kevin noted: “The concept is exciting, but there’s so much that can go wrong. It’s a huge risk, and it could either be an extraordinary success or a very expensive mistake.”

Despite the doubts, Howard and Sarah remained optimistic: “We know it’s risky, but it’s worth it. If we pull this off, it will be amazing.”

Building a "floating home" wasn’t as straightforward as Howard and Sarah had hoped. The first major hurdle was the construction of the polystyrene base, which was intended to provide buoyancy. However, this material proved to be difficult to handle.
Howard said: "We were expecting the polystyrene to be lightweight and easy to manage, but it’s actually really tough to get it in place properly."
The elements didn’t help either. The house was exposed to high winds and constant weather changes, and the team struggled to keep the build on track. "It feels like we’re fighting the elements every day," Sarah said, frustration creeping into her voice. “Everything takes longer than expected, and the process is far more unpredictable than we imagined.”
Kevin McCloud observed the ongoing delays and was candid about the struggles: “They’re facing more setbacks than I think they bargained for. What started as an exciting vision is now becoming a battle against the weather, against time, and against their budget.”
As the build stretched on, Howard admitted: "The dream is still there, but every time we think we’ve overcome one hurdle, another one seems to appear."
The end result: A house that stands out

Despite the challenges, the "floating home" was finally completed after 3 years and £465,000 to finish.
Kevin described its as a "steel cathedral" when he entered, saying the interiors "were really clever". The stand out is the kitchen with its hydrolic-powered windows that open up onto the balcony.
The kitchen island even opens out into a ping pong table. "It feels joyful to me", Sarah said.
