Fenland Baptist Chapel, before underpinning and conversion to a dwelling.

Built in 1908, this building had tilted shortly after construction and lay abandoned for many years. A reinforced concrete raft foundation has been inserted under the building and internally two storeys of accommodation have been provided while preserving the original features.

Bridle Joint on Roof Trusses before Erection

A combination of new materials and traditional techniques to produce a visually striking roof structure.

Reinforced Concrete Basement Wall

This prestigious new property was provided with a large basement with reinforced concrete walls.

Reinforcement for Football Stand Foundations

Pre-assembled cages ready for craning onto a piled foundation.

 
Fenland Pumping Station before Underpinning and Conversion to Dwellings.

This building originally housed a steam engine but had been superseded by diesel, then electric pumps. The building had subsided on the soft peaty ground and was underpinned using piles and a cantilevered floor slab with needle beams. Extensive rot damage was repaired and the walls restored using authentic materials.

Supermarket following Fire and subsequent demolition.

An emergency call-out ensured the building was made safe for contractors to enter the building and salvage valuable contents before the structure was demolished and rebuilt.

 New Warehouse built on Brownfield Site.

This site comprised filled ground with large concrete blocks preventing piling. Therefore, the piles of the former factory building were re-used to support the new warehouse.

 
Sussex Barn relocated and restored on a Retail Site.

This structure was bought in “kit form” by the owner, and erected as an HQ and reception for his landscaping materials outlet. Detailed repairs were designed and implemented, retaining the authentic features of the building.

 
New Assembly and Dining Hall for a Primary School.

The original kitchens for this Victorian School were converted to classrooms and this new facility constructed. The roof is supported on “Metsec” steel lattice girders to provide a clear space below.

Roof Trusses for a new Riverside Dwelling.

This prestigious new house was built on a piled foundation on the site of a house damaged by subsidence. The annexe was enhanced by the use of hand-cut trusses to support the roof.

 
Interior of Derelict Barn before Repair and Conversion.

Photographs and sketches are used to record original features of historic structures, so that repairs may be carried out, respecting the authentic methods of construction.

Roof Slab Reinforcement for a Lakeside Eco-Dwelling.

 The pioneering “zero-carbon” design of this new home allowed it to gain Planning Permission in a beautiful Victorian walled garden on the shores of Rutland Water. The reinforced concrete foundation and roof slabs are heavily insulated and designed for high thermal capacity, while using cement-replacement concrete. The building is recessed into the hillside to reduce its visual impact while providing stunning views over the garden and lake. To date, there has been no need to send any waste materials to landfill.

Failure of a Retaining Wall

Opening up this wall revealed that the original construction had never been designed to withstand the forces generated by the retained earth and groundwater. A set of alternative structures has been provided in order to obtain an economic and timely replacement.
