Base Structures has recently completed a distinctive new tensile canopy for E-ACT Montpelier High School in Bristol, delivered in close collaboration with Batterham Smith Architects, Tensys, and E-ACT. The project stemmed from a clear brief to turn an under-used rooftop into a multi-functional outdoor environment that could be enjoyed throughout the year.
The school and architects wanted to create a sheltered, flexible and attractive outdoor area where students could gather, learn or simply enjoy fresh air in all seasons. Base Structures designed and installed a tiered triple-conic tensile canopy, chosen for its coverage as well as the sense of lightness and space it brings to the rooftop environment.
The structure needed to provide sufficient shade and weather protection while acting as a standout architectural feature, and something that enhanced the school’s identity and provided a memorable focal point for pupils, staff and visitors.

To maximise the available footprint and retain as much usable space as possible beneath the canopy, Base collaborated with Tensys on a flying-mast solution. This approach allowed the structure to achieve its dramatic tiered form without compromising headroom or circulation.
Integrated drainage was incorporated into the design to ensure the canopy performs well throughout the year, keeping the rooftop comfortable and practical in all weather conditions.

Working in a dense urban environment always demands a highly considered approach, and E-ACT Montpelier High School was no exception. The site had limited access and its location meant that we had to install and manoeuvre large steel components from below.
The constraints required meticulous planning in the early design stages and by thinking ahead and modelling the logistics before arriving on site, the team ensured the installation proceeded smoothly and safely. Despite the tight constraints, the materials, steelwork and fabric were delivered and installed efficiently, which was testament to strong collaboration between all partners involved.

Beyond its functional role, the canopy was always intended to be a centrepiece. The tiered triple-conic form delivers a sense of scale and elegance that lifts the entire rooftop. The finished structure is practical and visually impressive, fulfilling the architects’ brief for a feature that would enhance daily school life while showcasing the possibilities of tensile design.
Vicky Fraser, National Project Manager at E-ACT, commented:
“Working with Base Structures and the team at Montpelier School has enabled us to create a truly valuable outdoor space for students. The new canopy provides much-needed shade and weather shelter, but more importantly it promotes outdoor learning, supports environmental stewardship and enhances student wellbeing. Despite the complexities of a tight, city-centre rooftop, the collaborative approach across all partners meant we could deliver a practical, beautiful space that will enrich school life all year round.”
Vanetta Spence, Headteacher at E-ACT Montpelier High School, said:
“Although installing the canopy during the school day was challenging, the result has been outstanding. It has transformed our outdoor area into a versatile, all-weather space that our students can enjoy every day, creating a comfortable and welcoming environment that enhances their school experience.”

As with all of Base’s year-round school canopies, the Montpelier School structure has been designed for longevity. To help keep the canopy performing and looking its best, Base offers a comprehensive range of cleaning and maintenance services, ensuring the school can enjoy its new space for many years to come.
