testimonial
“WP3 were appointed as Eastbrook’s MEP design consultants, overcoming legacy issues from our previous consultant’s designs. WP3 completed the extensive and specialist building services scope within our flagship London Studio development. WP3 provided unrivalled technical knowledge and were incredibly responsive throughout design, construction, and handover phases.
WP3 were also appointed as Eastbrook’s Commissioning Managers (CxA) overseeing the entire building services scope. WP3’s input was invaluable for bringing our multi acre project to life. We hope to work closely with WP3 very soon.”
