Contractors Design Partner

Do you require high quality drawings and technical schedules?

Do you require your designs to be returned on time, everytime?


CDP are able to offer a full range of MEP Design services with the belief that the right design with the right decisions will avoid problems later on in the construction phase. Therefore we work tirelessly with our design partners to agree co-ordinated concepts and space planning to ensure design decisions are fully agreed prior to the construction stage.


Although we traditionally work for contractors we also carry out Mechanical & Electrical projects for end user Clients and Architects where the team require a more traditional package with control over the Mechanical & Electrical designs.

We believe flexibility is the key to delivering a wide variety of projects in a fast changing world. Being a small company with a large variety of industry experience we can adapt quickly to modern challenges.


Client, Professional & Site Team Support Throughout Your Project.







We pride ourselves on the quality of our drawings and documents. We understand each client is unique, so to achieve the high quality workmanship required we must listen and adapt to these specific requirements.





We carry out full HVAC Mechanical and Electrical designs with sustainability and thermal modelling from our in house teams.

Although we are a multidiscipline practice, we are always very happy to work on single discipline packages if required. No project is too small or too big.





We believe in an open and honest approach to our work and to our clients and their project team.

We are always available to provide support throughout the project.

We hope these will provide an insight into the quality and detail we aim to provide on all projects.
