About Us

JCAD is an independent architectural practice set up by Jonathan Clarke in 2006, which specialises in house extensions, new build properties (both one off homes and small housing estates), and commercial property development.

Initially run as a part time operation alongside his work at national architectural practices, the demand for Jonathan’s services has continued to increase on the back of a growing reputation for high standards and customer satisfaction.

In February 2012 Jonathan’s client base had risen to the point that he had no option but to take the step of running the business full time.Whilst specialising in residential developments from small scale house extensions to new build homes and small housing estates, JCAD has also been involved in the design and planning of several bars and restaurants which have received recognition for the high standards set. One particular establishment in Arnold, Nottinghamshire received an award for Design Excellence shortly after opening in April 2008

With over fifteen years experience in the industry, JCAD is focused to work with and understand the requirements and expectations of individual householders, whilst also having the background, technical expertise and design flair to deliver imaginative and innovative solutions for both small- and large-scale assignments.

Our Design Ethos

JCAD recognises the need for a complete design service tailored to suit the individual needs of every client. This is backed up with technical knowledge and innovation to ensure that the end product exceeds client expectations every time.

It is this business ethos that has seen JCAD recommended by one satisfied customer after another. We recognise that a person’s house is their biggest investment and whether it is for a small single storey extension or a new build home, that scheme is the most important thing to that person and deserves to be treated as such.

For this reason we strive to ensure that all possible avenues of design are explored to provide an end product that is both practicable and far greater than first anticipated. We feel that these beliefs and ideals are in no small way to thank for our continued and increasing success in what has been a struggling market

By making our clients central to any scheme and assessing their every needs we will explore every possible avenue of design and often see potential for intricate or practical design features that will give your scheme an individual dimension

We deliver tailor-made designs with options as well as providing in depth technical knowledge and advice that will allow you to make an informed decision
