Cornerstone works with property developers and construction companies across mainland England to carry out a range of high quality works to domestic and non-domestic new build properties.

Our multi-disciplined installations teams can assist with a wide range of trades, in particular the façade and energy efficiency elements. We are an expert installer of render systems, using the variety of textures and colours available to achieve a modern and crisp façade, as well as cladding solutions for an alternative aesthetic. Additional features can be incorporated to achieve a high quality and low maintenance external finish.

Our solutions have previously contributed towards our clients achieving the Passive Haus standard of thermal efficiency on their new build projects.


Cornerstone is experienced in contributing to the achievement of the Passive Haus thermal efficiency standard


Cornerstone can also coordinate a range of trades in a main contractor capacity, including expert plumbers, electricians and heating engineers for first and second fix plumbing services and the installation of a range of heating systems and insulation measures.

Recent projects have included the installation of high specification underfloor heating in a number of exclusive new build developments, and the fitting of air source heat pump technology in rural off-gas sites.

Our design and installation team are adept at planning and delivering programmes of work regardless of the project size, budget and specification and in alignment with project timelines to achieve a seamless service for our clients.


“We are very pleased with the plumbing and energy efficiency works provided by Cornerstone for our Park Lane development. Their plumbers and engineers were hard working and highly skilled and have helped us to create some unique high specification homes. The project was very well managed, especially given the complex and diverse range of measures that Cornerstone installed; it was a great fit for us to be able to work with a single contractor that could offer the full range of plumbing, electrical and insulation services. We hope to work with Cornerstone again on similar projects in the near future.”
