Just Planning

Why we win 3 out of 4 planning appeals in Hillingdon

The London Borough of Hillingdon grants permission for only 60% of minor applications and 65% of householder applications, against a national average approval rate of 83% and 90% respectively.

In our experience, it takes a particularly hard line on applications for extensions (especially side and rear extensions) and applications for infill developments of a single new home.

A high proportion of our new enquiries come from the Hillingdon council area. We submit a number of planning appeals against planning refusals in the borough each year and we have had a success rate of over 75% since the beginning of 2014. We also help clients with enforcement problems and submit appeals against Enforcement Notices.

In 2014, we helped the owners of 59 Woodrow Avenue obtain consent for side extensions. The council considered that they looked out of place on the streetscene, but we successful argued that the extensions were well designed and an appropriate addition to the house.

In 2015, we helped Dr Mukerjee obtain permission, as appeal, for a small, rear balcony at 1A Frays Avenue. We demonstrated to the inspector that the balcony would not allow the occupiers of the house to overlook neighbouring properties.

We also submitted an enforcement appeal at 11 Cranford Park Road. The council wanted the homeowner to demolish an outbuilding at the bottom of his garden. We won the enforcement appeal and the outbuilding was saved.

In 2016, we had a number of successes relating to outbuildings (planning appeals, permitted development applications and enforcement appeals) and obtained planning permission for ground floor rear extensions deeper than the council’s usual maximum limit of 4m. We also obtained consent, on appeal, for a new dwelling on land to the side of 9 Fellowes Close, in Hayes.

This year we have won an important appeal relating to an outbuilding at 94 Marvell Avenue and an appeal against a refusal of planning permission for a first floor extension on Hoylake Road, in Ickenham.

We also have 5 other appeals pending and look forward to obtain more positive results for our clients.

We record details of a selection of our recent appeal decisions on our website.
