Barn Conversions

We also specialise in Barn Conversations and have recently completed several sizeable barn conversations overcoming significant planning and engineering challenges, to product a high-quality end product for our clients. Changing a barn over from its agricultural use to residential use generally requires significant changes to the integrity of the barn. Also, if the structure is of historic value, any changes must satisfy heritage requirements. We deal with all aspects of the barn conversion including any modifications to existing foundations and structural strengthening of the superstructure, which are common requirements with this type of project. Notable barn conversions include Bucks Hill Farm and The Christmas Tree Farm

Basement Construction & Underpinning 

The construction of basements in domestic dwellings in Greater London and the Southeast of England is becoming more practical due to the increased number of restricted sites because of increased demand for land. We also specialise in the construction of basements for domestic dwellings.  We have extensive experience in the successfully execution of a wide range of Traditional and Pier-and-Beam underpinning solutions on properties in Greater London area and the Home Counties and have an extensive working knowledge of the various types of ground conditions commonly encountered in these locations. Our primary objectives with this type of work are to get the job done quickly and effectively to a high standard of quality to minimise disruption to our clients, while at the same time ensuring that our work processes are carefully managed and tightly controlled to mitigate/eliminate the extent of ground movement, and the associated risk of damage to the original property and to any adjacent properties.
