A flagship office building within Brent Cross Town and a landmark example of Modern Methods of Construction, the scheme was delivered through close collaboration between multiple stakeholders. It stands as one of Europe’s tallest hybrid structures, combining precast concrete, structural steel, composite beams, and cross‑laminated timber (CLT).
The refurbishment of Pontllanfraith Comprehensive School’s Grammar Block created a dedicated facility for vulnerable learners while boldly reducing embodied carbon through the reuse of 35 tonnes of structural steel in the new sports hall.
The STEM building at the Institute of Technology Tralee is part of the HEB1 Bundle, a group of six projects across Ireland delivered through a Public-Private Partnership programme.
A state-of-the-art research centre for the University of Sheffield.
A national centre of excellence for structural dynamics research, acoustics and vibration testing for the University of Sheffield.
We provided civil and structural engineering services for the redevelopment of Market Square, Castle Street and Green Market in the heart of Carlisle, aiming to transform the heart of the city into a greener and more vibrant place.
Our innovative approach to due diligence, pre-planning and other development services.
Our economical remodelling of existing buildings to ensure they can reused or retrofitted in a sustainable, continuous loop.
Experienced assessments, investigations, appraisals and the development of cost-effective structural repair solutions for existing buildings, including non-traditional housing.
Green infrastructure led design promotes biodiversity and enhances the wellbeing of communities, so we bring this experienced approach to our projects in Wales, as well as the rest of the UK to deliver innovative and biophilic design, in harmony with the natural environment.
We understand the importance of conserving and sensitively restoring heritage structures so that their stories can continue and our connection with history is preserved. Our solutions are driven by our commitment to be sympathetic to the historically significant Monuments and Listed structures we design for, redevelop and regenerate.
At Curtins, sustainability is at the core of our approach as we strive to build a better future.
Curtins’ bespoke Insite service helps clients maintain the structural integrity of their built assets and confidently plan for their forward use.
With a rich history of embracing cutting-edge technology, we lead the way in digital delivery. Accredited with the BSI BIM Kitemark, we collaborate in a digital environment using the latest industry tools, and continuously enhance our digital capabilities to add tangible value to our projects.
At the heart of our innovative approach to building design is our commitment to delivering projects with unparalleled quality, speed, safety, and efficiency.
We specialise in the engineering of tall buildings, with expertise in wind load management, stability, and cost-efficient solutions.
We’re committed to making meaningful, measurable change, both within our own operations and across the wider industry. By leading, collaborating, and sharing best practice, we aim to maximise the positive impact we can make together.
We measure the carbon emissions of both our projects and our business to fully understand our footprint. Through detailed analysis and transparent reporting, we’ve set ambitious but achievable reduction targets.
Our goal is to reduce the average embodied carbon of our projects from 340kgCO₂e/m² to 295kgCO₂e/m² by 2030. As of 2026, we are exceeding this target.
By working proactively towards these targets, we’re helping to drive environmental improvement and move towards a more sustainable, resilient future for everyone.
“Curtins developed a design solution which minimised disruption to the building’s occupied spaces above by limiting the temporary propping to the basement and ground floors, avoiding the need for decant from the upper levels as well as resolving program risks to the construction stage. Curtins remained professional in their approach throughout and were equal to the difficult challenges posed by this project.”
