Greendoor Building Control was based in the North, South East and London areas. As a multidisciplinary Building Control practice they provided support services to a residential and commercial client base throughout the UK.

In 2015, Greendoor joined the Stroma Group, before merging with Approved Design and BBS to form Stroma Building Control in October 2018. Greendoor Building Control was formed by the now Stroma Building Control Managing Director, Steve Lonsdale.

Greendoor Building Control

Their service was provided throughout England and Wales from permanently manned regional offices. They used professional skills to find solutions whilst maintaining the importance of the client’s design. The Durham, Maidstone, Watford and Holborn offices are now part of Stroma Building Control’s national network of regional offices to serve our clients.

Steve is joined on the Stroma Building Control senior team by Jason Foster, Mark Ringshall and Stuart Martin, former Greendoor colleagues who now preside over key regional areas. Many of the original Greendoor team are also still working for Stroma as Building Control Managers, Building Control Surveyors and within our very talented admin teams.

The History of Greendoor Building Control

Greendoor Building Control & Specialist Services was a Corporate Approved Inspector, approved by the Construction Industry Council to check schemes for compliance with the Building Regulations.

As an Approved Inspector, they removed the need for Local Authority Building Control from a construction scheme. Their service checked, inspected and worked with clients to ensure compliance; following which, they issued the final certificate.

As a private company, they understood the commercial pressures within the construction industry and proactively worked to ensure the smooth running of a project. Their service was geared to save clients time and inconvenience.

All staff were professionally trained with many years of Building Control experience in both the private and public sector. Many of staff also held degrees in Building Control Engineering and were professionally qualified with the Royal Institution of Chartered Surveyors or Chartered Association of Building Engineers.
