Peter Wislocki, Managing Director

Founder and Director of iARCH Peter Wislocki is a bi-lingual architect and property development professional who is duo-located in the South of England and Poland. Peter has played a pivotal role in bringing hundreds of UK and international development, planning and architectural projects to a profitable – and on many occasions award-winning – conclusion during his professional career that spans over 30 years. Having studied at Cambridge University, Peter holds an MSc in Construction Economics and Management and is a recognised expert in his field as a practitioner, an academic and media commentator, a Design Review panellist for CABE and Design Council Expert, and a member of the Visiting Board of RIBA and ARB Prescription Committee.
I’ve worked with Peter Wislocki repeatedly over more than a decade, on projects ranging from a 20,000 sqm office building in Warsaw to a development of ten flats in Epsom, and even minor alterations to my house in Suffolk. Whatever the scale, budget and location, Peter understands my priorities, and achieves what I need.

Graham Kilbane,

Chief Development Officer, Atrium European Real Estate

I have had the pleasure of working with Peter Wislocki and his team recently on the proposed development of nine new apartments. Peter has worked tenaciously throughout the design process in order to come up with an innovative yet sustainable design scheme that met the Council’s stringent conditions required to achieve planning permission. Through his experience in dealing with planning control and his in depth industry knowledge, Peter was able to offer a no-nonsense, solution-focussed and hassle-free service which included acting as the main liaison between the local council and myself, successfully obtaining the planning permission required to proceed with the development. I found Peter to be ‘on the ball’ at all times and his flexible and accommodating approach meant that nothing was too much trouble. I would highly recommend Peter and his team and very much look forward to working with them again in the future.

Director Herald Build

We are very happy with your services.Firstly, we were encouraged by your positive attitude towards our somewhat unusual plot of land and history of the previous designs and applications for 48. We appreciated the clear fee structure broken down into stages with no hidden surprises. There was no pressure to proceed to the next stage, which allowed us to consider carefully what direction we took. All the information was clearly set out. There was great communication, whether by email, phone, zoom meetings or face to face. You responded very quickly to any questions and queries, and we didn’t have to chase you up. Very professional always. You provided us with a good network of contacts and recommendations for external suppliers such as a tree surgeon, light surveyor, builder and planning consultant. Although we had a fair amount on our wish list and a restrictive plot we were impressed by how well you listened, interpreted and produced creative ideas. You were enthusiastic and took on a previously well designed project and created a vision with exceptional design flair. Our passion for a cleverly designed house was matched by your interpretation and passion to think outside of the box. I think our dad would have approved of this exciting project.
