1. Planning History (covering the whole Leavesden Aerodrome site)

1.1 Background

1.1.1 The Leavesden Aerodrome site has a complex planning history. The site, which originally included land now developed to the east, has previously been owned by the Ministry of Defence where it was an important centre for the production of Mosquito and Halifax aircraft during World War II; and by Rolls Royce where it was used for the manufacture of helicopter engines until 1993. At its peak, the site employed over 3,000 people, but this had been reduced to approximately 1,800 by 1991. The airfield remained open for flying until March 1994, being used by a private flying club; the Leavesden Flight Centre. At its peak in 1990, there were some 60,000 aircraft movements at the site.

1.1.2 In 1995 the site was purchased by Third Millennium Group and part of the site was used as a film production studios. In 1999, the site was purchased by MEPC who leased the studios to Warner Bros. The studios are now owned by Warner Bros. and the housing site subject to outline permission 10/2230/OUT has recently been purchased by Bellway Homes (Phases 1, 3 and 4) and Bovis Homes (Phase 2).

1.2 Planning Brief

1.2.1 A Planning Brief was prepared by Three Rivers District Council and Watford Borough Council and approved for the site in 1993. This set out the principles to guide future development of the overall Leavesden Aerodrome site (totalling 119 hectares). The basic concept was to constrain development to the eastern part of the site and release the remainder of the site to form an attractive and accessible Green Belt wedge between Abbots Langley and Watford.

2. Site Description / Proposed Development

2.1 These reserved matters submissions relate to Phase 3 and Phase 4 of the development proposals granted outline consent under reference 10/2230/OUT. All matters, except for access, were reserved for future consideration. However, the proposals have been developed in accordance with the parameter plans approved as part of the outline consent, the outline consent conditions and the requirements of the associated Section 106 Legal Agreement. Essentially the parameter plans confirmed the number of private and affordable units (up to 425 units with 35% affordable housing), an 8500 sqm floorspace hotel, a 2350 sqm floorspace commercial centre comprising A1, A2, A3, A5 and D1 uses, new access points from Aerodrome Way with secondary access points from South Way and an average density of 40 dwellings per hectare, with densities greater towards the western side of the site nearest the film studios and adjacent offices and reducing in density to the north and east.

2.2 In addition, a Phasing Plan has been submitted and agreed pursuant to Condition 4 of the outline permission. The approved Phasing Plan detailed a 5 phase scheme, the hotel comprising the fifth and final phase (now subject of its own planning consent). Bovis Homes have now acquired Phase 2 whilst the current applicant, Bellway Homes, will continue to implement Phase 1. Bellway Homes have not acquired the hotel aspect of the scheme, this land is still owned by the original applicant MEPC.

2.3 The two schemes detail the proposals for the appearance, landscaping, layout and scale of Phase 3 and 4 of the residential component (with some commercial floorspace) of the outline scheme.

2.4 Phase 3 comprises a 3.59 ha site and is the most easterly part of the overall development site. Consent is sought for the construction of 86 dwellings (amended from 87) including 29 affordable dwellings. This Phase incorporates a wedge shaped area of open space towards the boundary with Phase 4.

2.5 Phase 4 extends to a 3.77 ha site and sits between Phase 1 to the west and Phase 3 to the east. It would comprise 114 dwellings (amended from 113) including 40 affordable units as well as a mixed use centre, sited opposite that forming part of Phase 1. The Phase 4 commercial floor space totalling 1149.03 sqm (gross external floor area) would be built in a 3 - 5 storey block comprising commercial floor space at ground and first floor level with flatted residential development above. The layout details remain indicative at this stage but would allow a range of uses including A1, A2, A3, A5 and D1 uses (amended plans indicate 3 of the units would be allocated for D1 use for a doctor’s surgery).

2.6 The schemes incorporate a range of building heights, predominantly 2 storey residential dwellings, interspersed with 2.5 storey dwellings. Flats are contained in a 3 storey block (affordable units) in Phase 3 and a 3 storey block (affordable units) and a 3 - 5 storey block in Phase 4 (private and affordable units).

2.7 Phase 3 would be served by a new access from the signalled controlled junction with Aerodrome Way/Hill Farm Avenue. Phase 4 would also be served by this access as well as a new access from the signal controlled junction with Aerodrome Way/Hercules Way which lies within the Phase 1 site. In addition 4 new access points would be constructed from South Way each serving a maximum of 6 dwellings. There would be no vehicular through route across the site from South Way to Aerodrome Way.
