Principal Designer

Ensure the safety of you, your workers and your building users.

We provide CDM15 Principal Designer consultancy both as a stand-alone service and as part of a complete construction package. To comply with the UK Government’s Construction (Design and Management) Regulations 2015 (CDM15) a Principal Designer must be engaged for all domestic and commercial projects. This is a vital role with responsibility for planning, managing, monitoring and coordinating health and safety during the pre-construction phase of any project that involves more than one contractor.

Construction Management

Service and experience in project delivery.

Any construction project is challenging and diverse. Construction process is closely regulated and to succeed it must be approached with realistic expectations.

Regardless of the size or complexity of project, we offer a straightforward approach to help your project meet your productivity requirements.


Design Supply

Optimise CLT’s structural, environmental and design properties for every project.

Working to Design for Manufacture and Assembly (DfMA) principles, we value engineer through the implementation of digital twin technology. This enables us to communicate effectively, solve problems and deliver projects with speed and efficiency.

We are dedicated to the
design and build of your
low carbon, mass timber projects

Our service packages are adapted to your project requirements
Projects managed via direct trade contracts


Building with CLT is a fast and highly efficient method of offsite construction resulting in low embodied carbon, energy efficient buildings. Operating on ‘just in time’ principles, the number of deliveries to site is minimised, as is disturbance to neighbours. CLT produces zero waste on site;  manufactured to mm tolerance CLT production is fully integrated BIM process which ensures accuracy of the material on delivery to site rather than relying on traditional workmanship.


The factory controlled manufacture of CLT is one of the material’s key benefits, providing precision engineering to 1-2 mm cutting tolerance and enabling an extremely high level of accuracy to be achieved at the design and engineering stages. Apertures and service channels are pre-cut in  factory conditions ensuring that buildings are completed as they were designed.


Prefabricated CLT panels cut to factory tolerances allow for high quality finishing and the creation of well-designed spaces. Internally, CLT is often left exposed as a key part of the design intent; the exposed wood creates spaces that are light and airy and at the same time warm and welcoming. The robust nature of CLT means that it a relatively low maintenance material.

CLT is a renewable, engineered timber structural element that can either be used for walls and floors or to form the superstructure of a building. CLT Panels are formed of bonded, cross-laminated single layers called lamellas which are glued at 90° to each other. The cross structure of CLT guarantees integral stability and dimensional accuracy and results in high strength panels suitable for all building typologies. Environmentally friendly glues are used for bonding.

Our world and its resources are finite. However, increasing demographics and urban densification will require the rapid deployment of quality infrastructure, that is developed for adaptability and cost efficiency.

Low carbon projects from early specification to their realisation.

We bring in technical and organisational expertise at the early stages when decisions are required and iteration less costly.
