Stanhope's Chiswick Park office development is light on colourful Richard Rogers touches and strong on refinement, parkland, barbecues and treasure hunts
Imagine Stockley Park updated to the 21st century and transplanted from the green belt near Heathrow to suburban west London. What you get is Chiswick Park, the first phase of which is officially opened this week. Both developments are the work of Sir Stuart Lipton, the chairman of the Commission for Architecture and the Built Environment and developer extraordinaire, and his company Stanhope.

As at Stockley, high-spec office pavilions are set in lush parkland, overlooking an artificial lake. But the suburban setting means that density can be increased, so that the pavilions are four-storey rather than two or three, and face each other across a central street. And the convenient location next to a Tube station means that only 15% of employees require car parking facilities. These are largely tucked below the office buildings.

Costing £90m, Chiswick Park is an altogether more controlled affair than its precursor – numerous placards bear the Orwellian command "" – and the construction of the eight Richard Rogers Partnership-designed rectilinear office buildings in steel and glass was ruthlessly standardised.

This meant that each block was built and fitted out in a record 40 weeks. It has also boosted the efficiency of the offices' floor space to a net-to-gross ratio of 87%. The buildings have even been shorn of Rogers' trademark flourishes of colour, leaving sheer but exquisitely detailed curtain walls enlivened only by automatic sun awnings and eaves-level canopies of aerofoil-shaped aluminium louvres.

As well as the sumptuous instant parkland of mature redwoods, gingkos and magnolias, and a sizeable waterfall, office workers will be seduced by barbecues, volleyball matches, bands and "London's most cryptic treasure hunt".

At Chiswick Park, Lipton promises its tenant companies a working environment so pleasant that workers on the site become more productive. This logic is spelled out to prospective tenants in the marketing brochure: "If people enjoy work, they do better work. If they do better work, you have a better business." Which is, of course, the whole point …
