KORR is a long-established practice based in Sussex, England, developing projects for residential, commercial and industrial complexes. We have vast experience in restructuring and the conservation of buildings, including listed buildings and properties in conservation areas. The practice also has expertise in space planning and corporate communication for offices, retail and hotels.


Our approach to every project is unique and individual, regardless of scale or complexity. We believe that a robust and rigorous analytical study of each project at an early stage will deliver the highest level of design quality, creating practical, sustainable and beautiful buildings.

Each proposal evolves through an understanding of the client’s brief, a study of constraints and potentials of the specific site, project’s needs and critical investigation into the social context. A well-developed brief integrates our project into the communities and their social and physical fabric, with significant reduction on overall time and cost during the planning process, and the life of the building.

From concept to construction

We provide an exceptional service – from design concept to detailed construction documentation and project management, from the building envelope to interior fit-out. We can also help when it comes to assessing the economic viability of a project, saving valuable resources while keeping the project on time, on track and on budget.

Projects are developed with the use of 3D computer modelling program and hand sketching, creating a powerful and easy-to-communicate tool, with integral and essential design documentation for bidding, fabrication, and construction processes.

Planning Applications

We have an exceptional success rate at achieving planning permission for small to large-scale projects when dealing with planning authorities. We have worked with many planning authorities in London, Southeast England and Scotland, including Westminster, Kensington and Chelsea, Mid Sussex and South Downs National Park, as well as many other planning authorities in Scotland. ​
