All of our Passivhaus designers and consultants initially trained as building services engineers. We bring a broad understanding of how the whole building comes together, with an engineer's approach to design and analysis.

We have access to a wealth of experience in passive building design, and to the powerful tools used by our building physicists. So we're able to quickly define the most appropriate building and services solution and guide it though to successful delivery.

Our Building Physicists also provide thermal bridge modelling, as required.

Senior Engineer

I like to think of services engineering as bringing a building to life. I start with an empty shell and turn it into a living, breathing place where people feel comfortable.

I create designs that go beyond their intrinsic functions, considering how each system will be installed, maintained, tested and understood by the end users.

One of the most rewarding aspects of my job is building relationships with design team and clients so that I can help turn their abstract ideas into an elegant design. Once I have understood their vision, motivation and goals I can design the engineering services to support and enhance this vision in a way that is implicitly understood by the end users.

I combine my engineering expertise with enthusiasm and clear communication, both to rally the team and to produce coherent and compelling design proposals. I always keep the overall project goals, deadlines and constraints in mind to help ensure my projects are delivered successfully in the client's eyes.

I have run projects at all stages, and worked on developments of many types including offices, schools, sports, leisure and housing designed to Passivhaus standards.

A demanding brief may lead to a complex system, but there’s no need to make it complicated.

As a designer, I’m looking to minimise mechanical and electrical engineering in a project. It’s an editing process. An ideal services strategy is one where there’s nothing left to take away. The systems that remain are necessary, simple to use and straightforward to maintain.

The way to achieve this is early involvement in the design process – having influence on the building’s form, orientation, façade and spatial organisation. From the outset, I aim to develop an elegant design; one that responds to the client’s requirements and the architect’s aspirations.

Buildings are part of our shared cultural heritage, experienced by everyone who sees them, whether they use them or not. I believe they should be designed to last. And I believe that the services should be appropriate and so well-integrated that they work well now and into an unknown future.

I find it satisfying when I am able to create simple, elegant, low-energy designs that provide a comfortable building for people to enjoy.

The sustainability aspect of our work is what drives me.  The fact that the buildings we build today will be there for the generations to come means that the design needs to be energy efficient and robust. 

I enjoy working to design constraints and finding ways of making things work, keeping both the architect and client happy. I’ve had the privilege of working on some great projects in my career with Max Fordham since joining as a graduate in 2013.

I have worked on many residential and visitor buildings, applying the principles of low energy design that delivers to the ambitions of the brief.

These projects not only cover new-builds but also many refurbishments of existing and listed buildings, which require an investigative mind to work within the constraints of the existing site and infrastructure. My experience in running projects on site has given me an in-depth understanding of how building systems come together.

I am also a certified Passivhaus designer.

Principal Engineer

I enjoy helping to deliver robust, low-energy designs that work and are sensitive to the building’s architecture, whether adapting an existing building, or developing a new one.

Essentially, it’s about appropriate design to meet the brief. I can deliver Passivhaus graduate accommodation for a Cambridge College, low-energy office buildings for owner-occupiers, and very simple, grassroots designs as part of Max Fordham’s Developing Countries Group.

I am a certified Passivhaus Consultant, lead Max Fordham’s Passivhaus service, and have more than 12 years of experience in construction across a range of project sectors, scales and stages. My project work includes new build, refurbishment and extension projects across a wide range of market sectors.

My Passivhaus experience includes acting as both Passivhaus Consultant and MEP designer on two new student accommodation projects encompassing 6 buildings, Cranmer Road and Croft Gardens, for King’s College Cambridge. I am also carrying out the Passivhaus consultant role on residential work for Agar Grove Phase 1C, a major 493-home Passivhaus development for the London Borough of Camden, and in the education sector on St Mary’s School Creative Arts Hub, a 4-storey education building for music, food technology, art and textiles.

I enjoy working on projects through all stages, right through from concept design to aftercare. This continuity enables me to get an understanding of performance in-use and feed this back into the design phase of future projects.

Throughout the design process I help optimise the building design using building physics and other modelling software, and then play an active role in site delivery and commissioning. With experience ranging from heating and water systems through to lighting and controls, I’m well-versed in delivering low-energy environmental design.
