Welcome to Kay Pilsbury Thomas Architects

Kay Pilsbury Thomas Architects is an award winning, 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 and have Accreditation in Building Conservation. Our projects 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 Essex, Cambridgeshire, Suffolk, Norfolk, Hertfordshire & Bedfordshire. Sibyl Thomas is an Architect Accredited in Building Conservation (AABC) and our close-knit, friendly team of Designers are all extremely experienced & qualified in historic buildings. 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.


If you like what you see, please contact us for a free initial visit to your property. We can then chat through all the ideas and will follow this up with a quote and explanation of the process.

Coronavirus update:

It’s business as usual!

We are following the Government Recommendations and this is being reviewed and updated daily.

All our Architectural Designers are currently working remotely on their KPT laptops, with full access to the company server and can be contacted on their mobiles or transferred from the studio and email as usual.

The studio is open with Sibyl and Jon taking calls until everyone is back soon. If we are out and about, and don’t answer the phone, please leave a message and we’ll call you back.

Site visits to Construction sites/your buildings are still taking place as required, keeping 2m distance, staying/ talking outside as much as possible, disinfecting hands before and after and we wear a mask when inside your house. We are tested weekly.

Planning Departments are currently operational and open, as are Construction Sites.

For New jobs/projects: We can easily quote and communicate remotely. Please just send us an email with photos and an agents plan (if you have one) and a description of the works you would like to do.

If required, Sibyl can visit until further notice or Government restrictions, and we can stay outside and keep 2m distance, disinfecting hands before and after. If you need us to go inside, we can do this without touching anything, wearing gloves and masks & disinfect our hands/feet with 70% alcohol spray, whilst keeping a distance. We will also check with you on the morning of the meeting that we/you & relatives are currently not high-risk and are currently showing no symptoms anyone is aware of.

For measured surveys of existing buildings, measuring outside is happening wearing gloves and masks, and if we need any internal dimensions we are asking owners to confirm those rooms only needed for the application, unless the building is vacant.

We are all still working hard on all our projects and are currently busy, as thankfully Architecture to date seems to be weathering the storm due to its remote design nature.

We hope this reassures you, do give us a call or email!
