CAD21 have more than 20 years’ experience in acute and mental healthcare building delivery.

This unparalleled experience has equipped us with a detailed understanding of this specialised sector where experience, quality and knowledge is critical. The CAD21 team understand health design – compliant, resilient, robust and quality-driven, and we thrive on engaging with people and organisations who share these values.

An enviable track record in acute healthcare across NHS trusts.

CAD21 have delivered an enviable amount of healthcare construction projects and have worked with multiple Trusts since we were formed in 1998. We are equipped with a thorough understanding of the latest guidelines, Health Building Notes (HBN) and Health Technical Memoranda (HTM) and the knowledge to add value when we consult fully with stakeholders to to gain a detailed understanding of both clinical and Estates requirements.

"CAD21 have always provided an excellent service and have shown a keen approach to efficient, compliant design. They work very well with our contractors, the client’s estates team and wider stakeholders. We would unreservedly recommend them as MEP designers, particularly for healthcare’’. Paul Jackson - IHP Health Sector Framework Manager

Ferndene Hospital

We’ve delivered in excess of £450m mental health construction in the past decade

A specialism in its own right, at CAD21 we have wide-ranging experience in interpreting patient needs and applying them to design. From low and medium secure in-patient facilities to specialist outpatient units, our team take great care in sensitively considering each aspect. For example, we know that when designing an Adult Autism unit we need to consider the finer sensory details – the noise, the lighting, the shadows being cast, rapid cooling and more are all key contributors to a satisfactory patient environment.

Airedale Acute Hospital

"Northumberland, Tyne and Wear NHS Foundation Trust has utilised the services of CAD21 on a number of major schemes. Their Mechanical and Electrical Building Services expertise and energy efficient designs and solutions have been excellent. Ease of communication and day to day advice has also been valuable to the Trust and has led to an on-going professional relationship over the past 15 years. We would have no hesitation in recommending CAD21 to any organisation requiring a Building Services Consultant" Malcolm Aiston BEng (Hons), CEng, MIHEEM - Director of Estates and Facilities

Energy and Sustainability

Our forward-thinking attitude and unique design approach allow us to create sustainable healthcare buildings of the future.

We firmly believe that dynamic and innovative design can help our customers and clients realise the cost-efficient and future-proofed results that are essential in this energy and cost-conscious sector. 

We achieve this by thorough interrogation at each stage of the health design process, involving the right people at the right time. 

You won’t find such a robust, process driven approach anywhere else, with proven results including a fantastic outcome on a recent £30m Acute hospital project achieving BREEAM outstanding, an ENE 01 credit score of 9 and well on the way to achieving a net zero operational carbon outcome.

“CAD21 have been involved in a number of major schemes with the Trust and their advice and expertise linked to energy efficient installations and solutions has been excellent - they offer a one stop solution to key areas required by NHS Trusts” Paul W Foxton - MCIOB Head of Capital Design, Tees Esk & Wear Valley
