About from company website

Mansouri Design & Build specialises in luxury homes, heritage properties, and bespoke construction, offering a comprehensive design and build service across Essex, Suffolk, and London. They address a common industry frustration by providing a single, coordinated team that manages architecture, structural engineering, planning, and construction from concept to completion, eliminating the gap between design and delivery. This integrated approach ensures that the final result accurately reflects the initial brief, leading to less stress, fewer delays, and a higher quality outcome for clients.

The company operates across three primary service areas: home extensions, landscaping and outdoor structures, and internal remodelling and design. Whether undertaking a single-storey extension, a complete garden transformation, or a whole-home renovation, Mansouri Design & Build maintains its commitment to a design-led process. They focus on adding value, not just managing cost, by considering the long-term worth of a project and ensuring good design and careful specification significantly increase a property's value.

Their expertise extends to heritage and period properties, where they employ a fundamentally different approach, understanding traditional materials and techniques to work sympathetically with existing historic fabric.
