Known as the Leonardo Building, the four storey offices will be built on the final plot of land in the Crawley Business Quarter in the heart of Manor Royal.

The scheme will comprise a TP Bennett design of four floors offering flexible, virtually column free, floor plates each of around 28,000 sq ft. Completion is set for the end of next year.

The building will target a BREEAM ‘Excellent’ standard and an EPC Rating of A or B together with a building design occupancy of 1 person per 6 sq m.

Mark Glatman, chief executive of Abstract Securities, said: “The Leonardo Building comes at a good time for the Gatwick office market, and, being located outside the boundary of the possible second runway, gives tenants absolute certainty about occupation whatever decisions are made about the potential extension of Gatwick.’’

The building is one of several speculative office developments that Abstract Securities has recently undertaken across the UK.

Having completed the 100,000 sq ft ‘Renaissance’ development in Croydon in November 2013, Abstract is currently on site in Glasgow where it is speculatively building the 170,000 sq ft ‘St Vincent Plaza’ office development, due for completion in Spring 2015.

In conjunction with Aker ASA, Abstract is also currently developing 1m sq ft offices at Aberdeen International Business Park, where the first phase of 335,000 sq ft is due to complete in February 2015.
