Integrated engineering consultancy

Cahill Design Consultants provide a range of services to projects across the built environment including acoustic design, fire engineering, facade engineering and building surveying, all under one integrated offering.  As a coordinated team, we align design proposals from the outset of a project, so advice is consistent and decisive.

The result is clear, coordinated decision making and advice, fewer late-stage changes, and a single point of technical leadership from feasibility and planning consent through to construction, completion and occupation. It is an approach built on strong technical expertise, a people-first mindset and a commitment to delivering safe buildings that achieve better outcomes for the people that occupy them. This model has built long-term relationships with repeat clients across the UK and internationally.

acoustic design

Acoustic Design Consultancy

Our acoustic consultants provide value adding technical advice that integrates seamlessly with the wider design aspirations for the project. Our early involvement as a key part of the design team helps align the acoustic requirements through all stages of the building design process, from feasibility and planning to building occupation and beyond.

On all of our projects, the focus is on practical advice and outcomes that enhance quality and compliance, prioritise occupant wellbeing and meet our client requirements.

fire engineering

Fire Engineering Consultancy

We support projects from feasibility and planning through to building control sign-off and beyond, developing fire engineering advice and strategies that respond to high standards for fire safety and Building Safety Act 2022 compliance in buildings.

Our team ensures that all our fire engineering advice aligns with the wider design requirements, collaborating clearly across disciplines from the outset. In addition, our integrated service approach is essential where fire performance intersects with facade specification or acoustic design. Our in house teams can resolve those points collaboratively, to the benefit of our clients.

Building Surveying Consultancy

For many building owners and asset managers, the Building Safety Act 2022 has set new standards for compliance and safety processes. Obligations that were not expected previously are now legal requirements.

Our building surveying team helps owners, landlords and asset managers understand these requirements and their legal obligations. This includes Principal Designer roles, Gateway applications, Building Safety Case reports, planned works, defect diagnosis and long term asset performance management. Where a building’s condition intersects with fire, facade or acoustic requirements, our integrated team provides a clear and coherent path forward.

Facade Design Consultancy

A facade does more than define how a building looks. It’s where fire performance, acoustic protection, thermal comfort and regulatory compliance come together. Decisions in one area can cause a ripple effect across the others.

Our facade engineers advise on systems, detailing, interfaces and specifications with a deep understanding that spans fire performance, acoustic requirements and building physics. Our integrated service approach allows for close internal coordination and collaboration across in- house disciplines. Working alongside our acoustic and fire engineering specialists, we understand how facade performance interacts with wider building requirements to deliver a compliant facade in accordance with our clients requirements.

Building Physics Consultancy

How a building performs in use is shaped long before people occupy the building. Decisions made at the design stage regarding daylight, thermal comfort and overheating have a direct impact on the health and wellbeing of the building’s occupants. These decisions are most effective when building physics forms part of the design conversation from the start.

Our building physics team delivers daylight and sunlight assessments, overheating analysis, and energy performance certification. We connect these findings to the acoustic, facade and wider design considerations being made alongside them. The result is an integrated analysis that informs design decisions rather than simply validating them.

Our People

Technical competence is an entry requirement. What sets our people apart is something more difficult to measure; professional honesty. It is harder to find than expertise, and more valuable to a client at the moments that matter most. We have built a team around people who have both. 

We are guided by conscience and driven by the lasting impact of our work. That means caring about what happens in the building long after our involvement ends, and being honest with clients even when the answer is more complex than expected.

Recent Projects

The most honest measure of project work is not what gets built but who calls you next. A significant proportion of our work comes from clients returning with a different building, a different sector, or a different challenge. That pattern does not happen by accident.

Our work spans hospitality, healthcare, education, leisure, commercial and mixed-use development across the UK and internationally. Every project is an opportunity to improve the built environment for the people who will live and work within it.
