About us

Henry Harrison qualified as an architect from the Architectural Association in 1975. After three years in general practice, he set up his own architectural practice, carrying out refurbishment and new build work in the South East of England.

After developing the Platonic Fireplace Company in 1984, he has remained at the forefront of contemporary fireplace and interior design. In 1993 Henry started Cope Conservatories, a bespoke conservatory manufacturing company, which he ran for three years before selling the business on. Remaining in the same field, The Platonic Folding Sliding Door Company has evolved as a result of Henry Harrison’s conviction of the growing need for high-quality boutique product companies in the building and interior design sectors of UK industry.

The Platonic Folding Sliding Door Company ethos:
We don’t promote cheap or inferior products. We believe that only the best quality will prevail over time. We keep our clients appraised of the best products available for their projects. We offer a full design serviced on all the projects because this guarantees the optimum outcome for the client. We take a keen interest in the detailing, because it is a vital part of the project design. We co-operate throughout the building process, to ensure the smooth assimilation of our products in the project fabric.
