Our team is formed with a combination of CAD technicians and services engineers who are all responsible for leading our digital design strategy on current and future projects.

We can work on various aspects of the same project, keeping the information safe and all team members updated on the project's progress.

Buildings are agents of interaction. People interact with a building, which then interacts with the environment.

As a designer, I consider the interplay between all the design parameters of a building to help create something that works and operates coherently.  

It all starts with the brief - a straight forward brief doesn’t have to imply a straightforward solution. It simply identifies all the aspirations of the project that need fulfilling; it defines the boundaries. I investigate the brief until I understand exactly what and where those boundaries are. That allows me to work with creativity and freedom within them. 

I like to design the building as if there are no electrical and mechanical systems - how can the architecture be optimised to make a naturally comfortable internal environment? When passive design is doing as much of the work as possible, only then do I add tech to maximise building performance. The result is lean, well-developed engineering that supports the architecture.

"My aim as a building services engineer is to ensure that we design buildings to be as efficient as possible. Whether that be by specifying the correct equipment or through the design process itself, it should always be our main objective to create a building that has a positive environmental impact on the world around it.

BIM allows for more efficient design of buildings, with the whole design team being able to effectively communicate their design solutions from concept to construction stage. Getting this right from an early stage is vital and makes the whole design process much simpler.

My engineering experience ranges from designing theatres to large scale residential schemes. I'm also a humble expert in modelling building systems and design solutions, including everything from service routes at concept stage, through to fully coordinated as-built BIM models for the client to use for commissioning or maintenance."

People respond to buildings in different ways, but it is difficult to bring all the elements together to give a sense of something less tangible: delight.

Delight is an often-overlooked quality in building design and it’s something I strive to create in my designs. Much of what we do as environmental engineers goes unseen – it’s in the walls, it’s in the floors and it’s in the air. But what we bring to a building can have a great effect on people’s moods, often without them knowing it.

I specialise in modelling, using BIM and building physics software to produce and test designs in 3D. I find the ability to manipulate and calculate using a 3D model invaluable and make use of the advantages of this quickly developing technology wherever possible to achieve more considered and efficient designs.

Buildings are not merely a series of separate systems - they come together to work as a coherent whole. One element of what I am designing almost always feeds into another. As such I always consider all the systems from an early stage, no matter how small, with the goal of balancing them to achieve a great result.

Kathryn Donald


BIM Leader, Principal Engineer

My approach to engineering has always been to look at the building and its services as a single entity; to view the building holistically, rather than thinking about the services without considering the whole building. To achieve this requires good collaboration between all design team members and with the client.

Having worked in a BIM environment since 2014, I have seen the potential of this framework to realise better project outcomes for everyone involved. One of the main strengths of the BIM process is increasing collaboration between all team members on a project so that the final building works better in operation.

I am passionate about the continual improvement of our practice’s capability through realising the benefits of these working methods. My role is to enable the practice to use BIM to further our ability to efficiently deliver sustainable and beautiful engineering.

Engineer, Digital Design Specialist

I have always been motivated to innovate and find better ways to do things. Beautiful engineering, to me, means striving to find a better and more sustainable way to deliver our designs, while maximising integration with the architecture.

I am passionate about sustainable design, building physics and new technologies. I combine my expertise in the digital environment with engineering design, and promote the use of digital tools and a three-dimensional approach as a way to improve efficiency and deliver a better quality design.

On all my projects I consider the whole picture, understanding the point of view of all the people in the client and design team, and adapting my design accordingly. I firmly believe that an excellent design can only be delivered through an intimate collaboration across all stakeholders and disciplines.

As a Digital Design Engineer, I am helping to lead the production of Revit guidelines for the practice and improving our workflows by using software interoperability and standardising common tasks.
