Ironically, Jarvis had a good month, but the other top spots are taken by French, Swedish and Australian firms.
overseas firms snapped up three of the top four spots in April. Bouygues headed the field with a £311m contract for the Home Office's HQ – three six-storey buildings linked by walkways that will include offices, apartments and retail space.

In second is Jarvis, thanks to four contracts worth £208.8m, and Skanska takes bronze, also with four contracts worth £197m. Australian firm Multiplex signed three contracts, bringing in £182.3m.

HOK stormed to the top of the architects' annual table thanks to 11 contracts worth £581.3m, and Twijnstra Gudde UK, a Dutch-based practice, is a shock second place. The Ministry of Defence has taken over from supermarket giant J Sainsbury as the industry's top client.
