E Z Design and Construction Ltd is a director-led specialist contractor delivering External Wall Insulation (EWI) and External Rendering solutions as part of a holistic, fabric-first approach to sustainable retrofit.

Led by Erdal Zorbozan MSc, the company combines decades of hands-on construction experience with formal qualifications in design coordination, site management, and sustainable building design. This integrated background ensures that insulation and façade upgrades are specified and delivered with careful consideration of building performance, moisture management, durability, and long-term energy efficiency.

Based in Swanley, Kent, E Z Design and Construction Ltd works across South East London and North Kent, supporting homeowners and property owners seeking technically sound improvements to existing buildings. Services are focused on improving thermal performance, reducing heat loss, enhancing comfort, and extending the life of the building envelope through well-detailed external wall insulation and high-quality rendering systems.
