This may have been the year of the housebuilder, but the sector's commercial cousin has fared equally well. Derwent London is top of the props for the fourth consecutive year - hardly surprising, given how well positioned it is to cash in on rising rents in the capital. Great Portland Estates, another London-centric developer, takes second place again, having seen the value of its portfolio rise 6.7% during its first half, plus the gong for use of corporate assets. After another year wrangling with locals and transport authorities over its giant Earls Court residential scheme, CapCo is third, with West End landlord Shaftesbury fourth. Retail specialist Land Securities is the only one of the top five not to focus exclusively on the south-east.
