Millbrook House Hotel

Sustainable and Characterful Art Hotel

Jersey, Channel Islands


With miles of beautiful beaches, stunning coastline and fantastic heritage, the Channel Island of Jersey has always been a popular destination. And it’s set to become even more attractive, as tourists from the UK and the continent look for safe places to holiday that are still close to home.


The perfect time, then, to invest in a sympathetic hotel development, transforming a listed hotel into five-star destination accommodation – and all with sustainability and community at its heart.


That’s the ambition of Lance Trevellyan at Trevellyan Developments, a Farnham-based business that has bought the Millbrook House Hotel in St. Helier and is planning a £14/£50m refurbishment project.

How we helped


  • Energy strategy planning
  • Building physical modelling

  • Embodied carbon analysis
  • Daylighting analysis
  • Initial MEP strategy benchmarking
  • RIBA 2030 Climate Change targets

There is a lack of dedicated eco-accommodation on the island, and the hotel will support consumer demand for sustainable visitor experiences. We expect Jersey to become a very popular destination on the post-pandemic tourism map, and travellers are becoming more determined to make sustainable travel choices.

The goal is to provide much-needed tourist accommodation on the island, and to do it with sustainable building practices that are in line with the island’s commitment to being carbon neutral by 2030. Architects’ plans are for 39 bedrooms, seven self-catering units and six eco-pods. The hotel will also have a spa and wellness centre, a hothouse cookery school and restaurant, and good quality staff accommodation – the hotel should create at least 40 new jobs. In addition, the team will completely restore the heritage gardens.

Trevellyan Developments needed an expert guide in building sustainable energy practices into the design and refurbishment of the building. Its listed status means that there may be restrictions or challenges that need to be met, and bringing in a dedicated energy consultant as part of the team allows the development to get everything right from the very beginning.


Mesh has worked on energy strategy planning, analysing the current building and the proposed changes to help Trevellyan Developments and its partners plan for a truly eco-friendly site. In particular, we looked at the RIBA 2030 Climate Challenge performance targets for operational energy use, water use and embodied carbon. These are progressive and holistic targets which will contribute towards the significant reductions necessary by 2030 in order to have a realistic prospect of achieving net zero carbon for the whole UK building stock by 2050.

Currently, Jersey lacks dedicated eco-accommodation and has a shortage in self-catering product, which we continue to see a surge in demand for. The development adds to Jersey’s tourism offering, particularly as we inspire visitors to discover the island year-round.

Trevellyan Developments was keen to use the RIBA 2030 targets as a basis for moving forward and has invested time and money to design a scheme that uses these targets as committed sustainability goals for the development. This approach has been a significant part of the overall presentation to the local planning department, and it means that the development will achieve RIBA 2030 levels almost across the board.

Millbrook House Hotel will be one of a very few projects to achieve these standards across the UK. This will be pioneering for Jersey, allowing it to set the bar highly for sustainable development on the island, and to show other multi-million pound development projects that incorporating sustainable design from the beginning isn’t just a ‘good’ thing to do – it’s the best thing to do.
