Project Description

Our initial development project was a critical step in establishing our brand and testing our business model in a real-world setting.


Project Proposals: 

The key proposal involved redeveloping the site known as Downside in Chipstead, Surrey. Our goal was to construct the area's first biophilic-designed, Passivhaus-certified, 3-bedroom dwelling. This plan also included a comprehensive soft landscaping and forest reinstatement program to enhance the visual appeal of the surrounding environment.


The project's main objectives were innovation, energy efficiency, substantial reduction of environmental impact, and enhancing the biodiversity of the area.


Planning Constraints: 

Metropolitan Green Belt: The Metropolitan Green Belt policy is designed to prevent urban sprawl by preserving open land. This policy is an integral part of the National Planning Policy Framework (NPPF), and all Local Planning Authorities are required to consider Green Belt policy in their Local Development Plans. We respect the value of this planning law in curbing urban sprawl. However, Downside was situated on previously developed land within this zone. Our plan was to integrate the site harmoniously with its environment by constructing a unique, unobtrusive structure that blended with the natural surroundings.


Tree Preservation Orders (TPOs) : Two magnificent Beech Trees under TPOs were part of the site. Our commitment was to protect and enhance their environment and foundations, ensuring their health and vitality throughout the project's completion and beyond.


The History of 'Downside': 

Our research indicates that Downside was formerly used by a London-based law firm. In 1959, it received planning approval to convert from storage to a combination of storage and habitable space for potential tenants awaiting new property purchases. No further historical records, plans, or photographs have been found since that date.


The 'Storage Bunker': 

The bunker, constructed post-World War II based on its design, is believed to have served as a storage unit or toilet facility for a former car garage on the site, now replaced by Tepestede Court.
