    I’ve worked with Peter Wislocki repeatedly over the last 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.

  • Creative designs shaped by your priorities


    iARCH has a breadth of architectural and property development experience that enables the design process to be shaped entirely by the priorities of clients, in the context of wider commercial, political, environmental and cultural constraints and opportunities. 

    This approach enables iARCH to design equally effectively regardless of whether the appropriate approach is uncompromisingly contemporary or more traditional, and whether the project is a true landmark or a more contextual element in the urban landscape..
