Eckersley O’Callaghan provided full engineering services for this modern extension to a Grade II-listed house in the Hampshire countryside. The extension respects the fabric of the original structure and provides a living room, dining room and bedrooms.

We provided full detailed design on the cross-laminated timber superstructure, including full connection design, which is normally provided by the contractor or a specialist timber engineering design consultant.

The extension is connected to the existing building by a frameless glass box, while the exterior is clad entirely in vertical timber boards for a clean, modern aesthetic.

We successfully met the client’s expected delivery date of one week. The whole structure was prefabricated offsite to reduce build time and disruption, and was erected and ready for fitting out in just five days.
