Welcome to Kay Pilsbury Thomas Architects

Kay Pilsbury Thomas Architects is a family practice of Chartered Architects and Interior Designers passionate about historic buildings and the stories they tell. We have dedicated our studio to working with old and listed buildings. These vary in type from Country Houses to Town Houses, Cottages, Barn Conversions, Manor Houses, Hotels, Schools and Churches to name a few! We specialise in high quality conversions, extensions and adaptations to historic buildings of all shapes and sizes.


KPT work on projects in the whole of Essex, Cambridgeshire, Suffolk, Norfolk, Hertfordshire, Bedfordshire, Buckinghamshire, London, Kent and Surrey. We are familiar with many of the Conservation Officers and Planners in these areas and have a select, high-quality list of local Craftsmen & Builders to ensure your building is finished to a superb standard.
