Some developers want GFA incentives restoredWITH profit margins already looking slimmer these days, some developers have decided to appeal to the Urban Redevelopment Authority (URA) to reinstate GFA (gross floor area) incentives for providing planter boxes and bay windows in condominiums.'URA checks on some completed developments had shown that on average, only about 10 per cent of the approved planter boxes within residential units were used for planting.' However, while sources say this is unlikely, an extension of the deadline for the approval of projects based on the old planning guidelines on planter boxes and bay windows may be given.In July, the URA announced that from Oct 7, bay windows and planter boxes, which can contribute up to around 5 per cent of a condominium's saleable area, will no longer be exempt from GFA calculations.Until now, developers were nevertheless able to charge home buyers for this extra GFA. But most developers do not see the GFA exemption as an incentive. City Developments group general manager Chia Ngiang Hong explained that it is common practice for developers to price in the exemption of GFA for planter boxes and bay windows when calculating the residual land value, especially for public tenders of state land. 'With the GFA exemption, most developers would have been able to allow for a wider margin,' he added.It is understood that developers were not consulted before the change in the planning guidelines on planter boxes and bay windows was revised, with many of them taken by surprise.That developers who bid for and were awarded land parcels based on prices that took into account the GFA incentive should now feel they could have overpaid, is likely to be a sore point. Still, design of future condominiums is also an issue.The guidelines on bay windows and planter boxes were first introduced in 1989 and 1993 respectively, ostensibly to encourage interesting designs for condominiums.
