A harmony of old and new.

Copperleaf, a striking contemporary home in Cheltenham, exemplifies how advanced construction techniques can harmonise with historic environments. This project, led by Psyte Architects, leverages over four decades of combined architectural expertise to create a residence that is both forward-thinking and contextually respectful.

Central to Copperleaf’s construction success was the use of the Structural Insulated Panels, chosen for its superior energy efficiency and speed of installation. Glosford SIPS played an essential role in coordinating and customising the system to fit the project’s unique requirements, including the narrow site, the need for a robust superstructure, and the integration of a basement level—an uncommon combination in SIPs construction.

Copperleaf’s design maximises the potential of its narrow infill site, with stepped levels that make the most of the building’s footprint. The front façade respects the historic context, echoing the gables and textures of the adjacent Victorian architecture. At the rear, expansive double-height glazing opens the home to a private garden, enhancing the sense of space and capturing the leafy surroundings.

The house comprises three double bedrooms and a mezzanine study, designed to achieve a high sustainability rating. The planning process was particularly challenging due to the site’s physical constraints, including its narrow width, location on a neighbouring boundary, and a lower ground basement level. The design underwent several iterations to align with both site constraints and planning requirements, resulting in a harmonious balance between traditional aesthetics and modern performance.

After evaluating various construction methods, the team selected a combined approach using a SIPs superstructure with a concrete retaining wall and basement level. This approach is unique, especially given the complexity of integrating Structural Insulated Panels with a basement and retaining wall on a boundary site. The team developed tailored solutions to ensure the systems could work together effectively, meeting both the structural and sustainability goals of the project.

Glosford SIPS’ role was critical in adapting the Structural Insulated Panel System to these complex site conditions. The use of SIPs was preferred not only for its sustainability and energy efficiency but also for the speed of construction it allowed, which was crucial given the site’s constraints and the project’s mid-winter timeline.

Swift and Efficient Installation:
The SIPs system allowed for a faster construction timeline, which was particularly advantageous during the winter months. This efficiency reduced on-site time and minimised disruption.

Enhanced Energy Performance:
The airtight and highly insulated properties of the SIPs system significantly contributed to the home’s energy efficiency, aligning with the project’s sustainability goals.

Adaptation to Site Conditions:
Glosford SIPS expertly adapted the system to manage the site’s specific challenges, including retaining wall conditions and the tight boundary, ensuring the structural integrity of the building.

Precision Engineering:
Through the use of BIM modeling and digital fabrication techniques, the project benefited from minimal material waste and exacting construction standards, reinforcing both the environmental and structural goals of the project.

Copperleaf is a prime example of how modern construction methods, particularly the use of SIPS technology, can be successfully integrated into complex, sensitive sites. The careful integration of traditional and contemporary design elements ensures the home is both visually appealing and energy-efficient. Glosford SIPS’ expertise was instrumental in achieving a structure that marries contemporary efficiency with architectural integrity.

James Sandwith, Director – Psyte Architects:

“The application of SIPs in the Copperleaf project allowed us to achieve a level of energy performance and construction precision that was crucial for this site, ensuring the building not only meets modern standards but also respects its historic surroundings.”
