The team

Owner/Project Manager Guy Greenway

Guy works as project manager and will be your first point of contact, ensuring that your project runs smoothly. Guy offers a wealth of knowledge and experience, having worked on property restoration, development and basements in London and East Anglia over the past two decades.

Construction team, finishing and fit-out

We employ foremen and ground workers from the London market who create the structural shell of the basement. We can organise and coordinate specialist tradesmen including carpenters, electricians and plumbers needed to deliver the project.

Engineers, surveyors, architects and building control

We have strong relationships with architects, structural engineers, party wall surveyors and building control. We can provide coordination of this area of your project if needed.
