BoonBrown first began working with Westland Helicopters Ltd (later AgustaWestland and now Leonardo Helicopters) in the 1980s and have over the years been commissioned on many projects including;

• a new four-storey Office Block (20.000 sq ft);
• an Aircraft Assembly Facility (25.000 sq ft);
• a Gearbox Testing Facility;
• a Carbon Fibre Blade Research Centre ;
• a Fuel Flow Bay Test Facility;
• a Structural & Mechanical Test Facility;
• and other Manufacturing Buildings.

Many of these projects have specialist requirements which required BoonBrown to engineer bespoke design solutions such as internal lobbies, air-conditioning to class 10,000, clean rooms, large autoclaves, chemical fume extraction, acoustic isolation and protection, chemical and hazardous substance storage and containment.
