Property specialist Stoford Developments is developing the 66,000 sq ft office building on a one-acre site in Enfield.

Work is expected to start at the £27m Genotin Road project this month, with McLaren erecting a five-storey building to BREEAM ‘Excellent’ standard over the 20-month programme.

The building will hold an advanced data centre, rooftop conference centre as well as feature, full-height atrium, for up to 500 staff.

Stoford director Gerard Ludlow said: “We’re pleased to have reached the next stage of this major investment for Metaswitch by appointing a contractor to deliver this impressive headquarters.

“It’s not only good news for the company, which is growing, it is also good news for the town, because a major employer is committed to remaining in the area where it started more than 30 years ago, creating new jobs and opportunities. The local community and Enfield Council have been extremely supportive throughout the process and we’re now looking forward to beginning on site.”

Jay Newman, McLaren’s regional managing director for the South, said: “McLaren has successfully delivered a number of developments for Stoford and we are thrilled to be working with them again. We have an extensive portfolio of commercial offices of the highest quality and we look forward to delivering a new home for Metaswitch.”
