About Jonathan Clements Architects

We are a Sheffield-based architectural practice specialising in home extensions in Sheffield, Yorkshire and Derbyshire. We work on projects ranging from modest single-storey extensions to two-storey extensions and loft conversions.

A focus on your needs

Everything we do is based around our clients. At the start of a project Jonathan will talk to you about your needs and ideas, and work with you to design the perfect space for you and your family. Then we set about making your dream home a reality.

Every aspect covered

We have long-established relationships with builders, structural engineers and planners – so, unlike some practices, we offer the whole service from initial consultation to finished build. We’ll also be your main point of contact at every stage of the project, so if you encounter any issues during construction we will sort it out for you.

Experience and expertise

Jonathan leads every project and has 15 years’ experience as an architect. All our other architects have gained legal training through their accredited Royal Institute of British Architects (RIBA) Parts 1, 2 and RIBA Part 3 (Professional Practice) qualifications and are members of the Architects Registration Board (ARB).

Meet Jonathan Clements

‘As the founder and owner of the practice, I lead on every project. I’ll use my 15 years’ experience as a qualified architect to help you achieve your ideal space and add value to your property. 

‘I’m fascinated by how people and families use their living space, and how buildings can improve your quality of life. My guiding design principles are improving the feeling of light, space, materials and views in your home, while maximising your budget and the value of your property.

‘I love meeting people and talking about their requirements – every project I work on is different. What connects them all is my passion for design and the thrill of seeing a brief turned into reality.’
