Farmhouse Extension, Perthshire

Our client wanted to extend their traditional farmhouse to accommodate their expanding family and they decided to increase the size of the property from 180m2 to 360m2 – effectively doubling its size. The architect’s brief was to increase the number of bedrooms from three to five and also include a generous open plan kitchen/dining room with boot room, laundry room and WC. The client wanted to mirror the existing traditional architecture within the new accommodation whilst ensuring the extension was as thermally efficient as possible and were therefore very keen it was built in SIPs (Structural Insulated Panels).


Marrying new structures to old, traditional buildings is always a potentially difficult proposition but with accurate site surveying and 3D modelling jML ensured this was flawlessly achieved. The existing stonework was matched using reclaimed local stone with lime pointing and the new extension roof was slated using reclaimed Scottish slate from a local supplier. Utilising an AGA cooker in a kitchen within an incredibly well insulated SIPs frame has the potential to create overheating issues in summer months. To overcome this issue a bespoke design for the HRv (Heat Recovery ventilation) system was used helping to distribute any excess heat throughout the rest of the house.

JML Contracts carried out all aspects of the project from demolition, groundworks and foundations through to the supply and erection of the SIPs kit and all internal finishings. Upon completion of the project, it was extremely difficult to tell the difference between the old farmhouse and the new extension due to the stone cladding and roof matching so well. Underfloor heating was installed throughout the ground floor of the extension although our client has since informed us it is barely used due to the insulating properties of the SIPs kit.

This completed extension was given a centre spread in 25 Beautiful Homes Magazine in june 2015.
