Many viewers will remember Piers Daniell from his appearance on Grand Designs, where his ambitious castle restoration project captured the imagination of audiences across the UK. A year on from the programme, many people still search for updates on what happened next.

So, what is Piers Daniell doing now?

While the castle remains an important part of his life, much of Piers' focus today is on building Tewke, a British smart home technology company focused on making homes more intelligent, energy efficient and easier to live in.

The castle project continues

For Grand Designs viewers, the castle restoration is often the first thing that comes to mind when they think of Piers Daniell.

The restoration remains an important part of his life and continues to move towards completion. Like many ambitious heritage projects, bringing a centuries-old building back to life takes time, patience and a long-term commitment to getting things right.

But while the castle introduced Piers to a national audience, it is far from the only project occupying his time. In the years since Grand Designs, he has turned his attention to a new challenge: developing technology that helps homeowners create more intelligent, efficient and responsive living spaces. Today, much of his focus is on Tewke and the development of its smart home products, Tap and Tap One.

Building Tewke

Alongside the castle project, Piers has spent recent years developing Tewke, a UK-based smart home platform designed to simplify the way people interact with their homes.

The idea behind Tewke is straightforward. Smart homes should make life easier, not more complicated.

Many smart home products require multiple apps, endless settings and constant management. Tewke takes a different approach, focusing on intuitive technology that works quietly in the background while helping homeowners improve comfort, convenience and energy efficiency.

At the heart of the platform is Tap, Tewke's intelligent smart light switch.

The development of Tap and Tap One

Tap has become the centrepiece of Tewke's product development.

Unlike traditional light switches, Tap allows homeowners to control multiple lighting scenes from a single switch, helping create different moods and environments throughout the day. Whether it's a bright morning setting, a relaxed evening atmosphere or a simple all-off mode, Tap is designed to make controlling lighting feel natural and effortless.

The product has been developed to work with existing UK wiring, making installation straightforward for electricians and reducing disruption for homeowners.

Alongside Tap, Piers and the Tewke team have also been developing Tap One, expanding the company's vision of creating connected, responsive homes that adapt to the way people live.

The broader goal is not simply to add more technology to the home. Instead, Tewke focuses on helping people better understand and manage their environment while reducing unnecessary energy waste.

A focus on energy and sustainability

Energy efficiency has become an increasingly important part of Tewke's mission.

The company believes that homeowners should have greater visibility over how energy is used within their homes and be empowered to make informed decisions about consumption.

Through intelligent automation and thoughtful design, Tewke aims to help households reduce waste without requiring significant lifestyle changes.

It's an approach that reflects a wider belief that smart technology should support people rather than demand their attention.

Where can you learn more?

For those interested in following Piers' current work, the best place to start is the Tewke media centre, where the company regularly shares product updates, announcements and insights into its vision for the future.

You can also revisit Piers' Grand Designs journey on YouTube, which continues to attract viewers interested in one of the programme's most memorable restoration projects.

While the castle remains an important chapter in his story, much of Piers Daniell's attention today is focused on a different kind of building project: creating technology that helps homes become smarter, more sustainable and more responsive to the people who live in them.
