We were asked to create a bespoke glasshouse to replace the original structure for the walled garden in the Thenford Arboretum.

Working alongside Head Gardener Darren Webster and Garden Designer George Carter, we created a new feature glasshouse that would replace the original nineteenth century wooden structure that sat against the north wall. Darren’s experience as Head Gardener on the Thenford Estate for over twenty years and a practical interest in engineering, made him instrumental in helping design and layout the new glasshouse.

The complexity of the build and necessity to retain the existing wall meant that this project needed careful consideration and design. Our Sales Director, John Lawson lead the project and liaised with all involved throughout the build.

The glasshouse itself features a central octagonal display house, flanked by two lean-to wings that are used for overwintering citrus fruits. Unusually, the south rear wall was part flued and given the depth of the octagonal feature lobby, we decided to draw air into the glasshouse via ducts at the rear, from that flue.

The structural integrity of the glasshouse base was crucial for us to install the aluminium frame on top. Due to the flued wall being slightly weaker than necessary, our engineering team determined the frame needed additional support posts at the rear of the structure.

The more intricate details of the internal space were carefully designed, with nine independent sections. Internal heating is generated by two oil-fired boilers with their control panel fitted in the potting shed at the rear of the glasshouse. Given the size of the structure and particular environmental controls needed for specific growing requirements, a separate boiler house with a hot water piping system was also installed.

Marston & Langinger by Alitex listened to the requirements of those who would utilise the structure, ensuring every aspect from the design to execution were thoroughly tested to meet the highest standards whilst in-keeping with the surrounding aesthetic of the gardens.

Thenford Estate is open to the public on various open days throughout the year. To discover how you can explore the gardens visit here.
