Floyd Slaski is an award winning architectural practice proud to have been serving great clients and creating enriching architecture since 1952. We have developed particular specialities in healthcare design, both private and NHS and we are honoured to be on both the SBS and LPP frameworks.


We are based in London and our portfolio of past schemes illustrates a wide range of expertise and provides clear evidence of satisfied clients stemming from the large number of repeat commissions. 


Above all else we pride ourselves on our ability to listen, to learn and to react imaginatively. Every building project is different. We acknowledge this and respond accordingly, providing our clients with the quality solutions they demand. We would be pleased to hear from you. 

SBS Framework:


Floyd Slaski were delighted to be reconfirmed as members of the Shared Business Services (SBS) Framework, meaning our NHS clients can appoint us through direct call off using our pre-agreed rates and avoid the time and cost involved in conventional procurement methods.

Architects for Health Members

"AfH is a non-profit organisation for those interested in improving health and well-being through healthcare design, underpinned by a membership of design and related professionals. Its inception in 1992 was a response to the considerable strategic change in the health sector. Since then, AfH has established itself as a forum for new ideas and a place to share best practice."
