Planning Guidance


The team comprises sustainability specialists from architectural and scientific backgrounds all working with a common goal to produce the best most beautiful buildings and places.

By bringing together experts in sustainability from different backgrounds we take advantage of opportunities a less integrated approach might not even find.

Hero Bennett


Senior Sustainability Consultant

I help clients to explore, define and achieve their sustainability aspirations. My work helps form excellent sustainable design that is appropriate for users, the site and the wider environment.

My experience gives me a broad understanding of what sustainability issues need to be considered during design. Having taken projects from design to site as an Engineer, I can appreciate some of the practical difficulties in delivering sustainability targets.

Communication throughout the process is key to overcoming these difficulties. I’m trained to facilitate sustainability discussions to set the aspirations and brief, communicate design options and help the team choose effective design strategies.

I also have experience explaining sustainability externally, through both public consultations and in presenting 'The Sustainability Matrix', a communication tool developed by Max Fordham and published in the Architects Journal in 2010. The work is varied; from looking at material selection for a private house to developing a masterplan’s sustainability and energy strategy. I’m interested in it all.

I am also experienced in Passivhaus design.

Senior Sustainability Consultant

I am passionate about sustainability and design. I enjoy working within a team and with clients to develop creative solutions that have tangible results.

A project works best when a sustainable approach is chosen right from the start. I assist in integrating environmental aims into the design process, helping a project’s sustainability credentials to be truly interwoven.

I’m keen to help clients and designers understand and communicate sustainable design effectively.. As well as holding and facilitating Sustainability Workshops for clients, I’ve written sustainable design guides and generated sustainability key performance indicators for masterplans. I have also written a property selection tool and sustainability design manual for the British Council to help ’green’ their offices all around the world.

Sustainability involves so much more than energy. I’m also interested in looking at environmental footprinting, corporate social responsibility and behaviour change.

Sustainability Consultant

'Sustainability can mean a lot of things to a lot of different people.'

One of the things I really enjoy doing is working with clients and other stakeholders to help them understand what it is they want from their project.

The result of that engagement is a client with a clear vision for their project and a design team with the clarity to tailor their response to that vision.

The ability to communicate clearly is central to my role. I favour a visual approach to my work, using drawings, diagrams and infographics to develop ideas and relay them to the client and the design team. It’s an iterative and fluid process.

I have had the opportunity to work on a range of different building types and scales, with the added benefit of working in diverse locations around the world. The unique challenges of cultural buildings are a particular highlight, but I’ve also worked on education, commercial, sports and retail schemes.

Sustainability Consultant

There’s something satisfying about being in a well-conditioned space, where the temperature is just right, the air is fresh, the light-level appropriate.

But the things that make a difference to how a building feels are not immediately obvious to the eye. It’s about having the right systems in place and the processes that support efficient building operation that make the difference.

My background is in psychology, environmental design and architecture and I think this is a potent combination for making better buildings. Design can influence human behaviour, but the complexity and reality of human behaviour should also influence design.

I advise design teams on how they can apply sustainability concepts and methodologies to produce better buildings; buildings that work. BREEAM is one of the useful tools that can help meet this end. When approached in the right spirit as a holistic and robust standard rather than another form of compliance, it provides an excellent framework to ensure that the details that deliver better building survive to the end of the construction process.

Ingrid Berkeley


Sustainability Consultant

Buildings in the UK account for a huge quantity of carbon dioxide emissions - as high as 45% of our overall output.

Being able to make a positive difference in reducing the built environment’s consumption of natural resources, and to mitigate the impact of climate change, is enormously important to me.

One of the conditions that weighs heavily on a building’s energy performance is complexity. Too often unnecessarily complex designs mean a building performs badly because it’s difficult to operate, and things go wrong. I aspire to simplicity, and I privilege passive design over mechanical intervention.

My role covers many aspects from advising on low carbon techniques for generating energy on site, to carrying out Post Occupancy Evaluations to ensure the building performs as designed. I’m also a Soft Landings champion and joint BREEAM Manager for the Practice.

There are powerful ways we can improve the performance of our buildings and reduce their impact on the planet. I love playing my part in that outcome.
