424 homes at One Horton Heath, Eastleigh

“The application site comprises the third phase to come forward for residential development as part of the One Horton Heath mixed-use allocation, identified under policy HH1 of the Eastleigh Borough Local Plan (EBLP). The wider scheme will deliver up to 2,500 dwellings alongside a local centre, school, business uses and associated open space and infrastructure.”

“6 Beyond the site to the north are fields identified for future development as part of One Horton Heath, as shown on the approved Masterplan. These areas are proposed for sports pitches and allotments, with a primary school forming part of the local centre located further to the north.”

“The principle of development is not relevant to a reserved matters application and was established at the outline stage (ref. O/20/89498).”

“46 The reserved matters are the four main matters that are for consideration, namely the proposed layout, the scale of the buildings, the appearance of the buildings, and the landscaping.”

“84 The principle of development has been established by outline permission (O/20/89498) and the current application is therefore assessed solely in respect of the reserved matters of layout, scale, appearance and landscaping. The proposals have been considered against the approved Parameter Plans, the One Horton Heath masterplan and the Design Code secured through the outline permission.”

“85 The layout ensures outward-facing development to key edges and integrates SuDS, structural planting and open space as defining components of the design. The scale and massing of all buildings are appropriately varied and carefully located, with taller elements and apartment buildings reinforcing gateways, junctions and principal routes, and with heights stepping down towards Burnetts Lane and adjoining residential areas to secure a sensitive interface.”

“Matters Relating to reserved matters (Layout, Scale, Appearance, Landscaping, Amenity); • Over-intensive layout and excessive density within the Upper Acre parcel. • Inadequate separation distances resulting in overbearing impact and loss of outlook to neighbouring properties (notably Flower Cottage). • Overlooking from upper floor windows leading to loss of privacy. • Height, bulk and massing create sense of enclosure and dominance.”

“Outline/Principle Matters; • Objection to cumulative scale of development within One Horton Heath (overdevelopment concerns). • Additional 424 dwellings considered to exacerbate existing infrastructure pressures. • Increased traffic congestion and highway capacity concerns. • Insufficient healthcare, education and service provision to support growth.”

“Public Right of Way (Footpath 702): The route falls within the application site and is subject to a confirmed diversion order, which has not yet been brought into effect. Request that the diverted route is fully constructed and certified prior to the commencement of development. • Pedestrian Safety / Connectivity (Burnetts Lane): Concern regarding the narrow nature of Burnetts Lane and increased traffic, creating hazards for pedestrians.”

“44 Hampshire Swifts Comment - Request that there should be at least 1 swift brick per home on average across this development.”

“[NOTE: (A)The Committee praised the engagement the OHH team had carried out with the residents of Barley Fields and the improvements made to the scheme which had resulted in no objections. The Committee also expressed how impressed they were with the design of the scheme; (B) Councillor Marsh raised the issue of flooding on Burnetts Lane and wanted to ensure that the ditches would be cleared so that the development did not exacerbate the issue.]”

“That the Committee approved the reserved matters with conditions as outlined in the committee report and approved the relevant outline planning permission conditions:”

“The development hereby permitted shall be carried out in accordance with the details in the Drainage Strategy (Arch Associates, November 2025 ) and Designers Response to LLFA comments (Arch Associates, February 2026) (other than where these relate to condition 59 of the Outline Permission O/20/89498) which has been submitted to and approved by the Local Planning Authority in accordance with paragraph 14(2) of Schedule 7A of the Town and Country Planning Act 1990 and shall be…”

“Amended Condition 6 with additional plan reference added:”
