In Ian's early career, he was often involved with historic building restoration, working with acclaimed organisations such as The National Trust and English Heritage. Whilst it was a privilege to work on such projects, Ian found the work creatively stifling as the design and innovation aspects were often missing for him.
Combining formal training, traditional skills and an eye for beauty, Ian has gone onto developing his business and portfolio to include work that equally embraces the design and innovation aspects along with the craft of making. From inspired corporate interiors to captivating private homes, Ian's stonework creates a lovingly considered backdrop.
To incorporate interior architecture with stone is to make a lasting commitment to the quirks and character of any property. The team at Ian Knapper is fully committed to producing thoughtfully crafted staircases, fireplaces and other unique schemes featuring bespoke stonework that capture the essence of a space and enhance it.
From the first contact with our team until completion, our clients benefit from our personal care and attention. Our makers are invested in preserving and enhancing the nature of the world’s most prestigious homes and buildings for generations to come.




Cantilever staircases appear to float out from an adjacent wall with beautiful effect. Technically, the term ‘cantilever’ is somewhat of a misnomer in respect of these staircases. The stairs don’t actually cantilever at all, instead acting in much the same way as an arch.
Traditionally, the design of both curved and cantilever staircases has been somewhat restricted by engineering limitations. Here at Ian Knapper we have rewritten the rules on what is possible using solid natural stone with our bespoke cantilever staircases; creating visually arresting and elegant effects.
We work hard to create bespoke cantilever stone staircases that match their surroundings perfectly. By developing new techniques, we are able to produce cantilever staircases in shapes and sizes which were previously thought to be impossible.
