Background
The London Borough of Haringey is defined by its architectural landscape that combines historic and contemporary styles across its varied neighbourhoods. From Victorian and Edwardian homes in Highgate and Crouch End to the post-war estates of Wood Green and Tottenham, Haringey’s built environment reflects its evolving urban and suburban character. The borough's architectural heritage is complemented by areas of active regeneration, where innovative new developments and sustainable housing schemes are reshaping its streetscape.
With a mix of conservation areas and more modern areas of development, Haringey presents both opportunities and challenges for homeowners employing architects. Whether working on sensitive restorations, adaptive reuse projects, or contemporary new builds, careful consideration must be given to preserving the borough’s unique architectural identity while embracing modern design principles.
Housing Typologies in Haringey
Victorian & Edwardian Homes – Period properties, often featuring bay windows, decorative facades, and generous interiors. Homes in areas such as Muswell Hill, Highgate, and Crouch End are frequently restored or extended, with careful attention needed to maintain their historic character while improving modern living standards.
Arts & Crafts & Garden Suburb Homes – Characterful homes influenced by the early 20th-century Arts & Crafts movement, particularly in areas like Muswell Hill and Alexandra Park. With steeply pitched roofs, timber framing, and handcrafted details, these properties require thoughtful restoration and high-quality materials to retain their original charm.
Interwar & Suburban Housing – Semi-detached and detached homes, commonly found in areas such as Bounds Green and West Green, reflecting Haringey’s suburban expansion during the early 20th century. These homes offer great potential for extensions, internal reconfigurations, and energy efficiency upgrades.
Post-War & Social Housing – A mix of mid-century housing estates, high-rise developments, and modernist schemes, including notable examples such as the Broadwater Farm Estate and smaller-scale post-war council housing. Many of these estates are now the focus of regeneration projects aimed at improving living conditions while respecting their architectural significance.
Modern & Sustainable Developments – Recent developments in Haringey emphasize energy efficiency, high-density living, and contextual sensitivity within the borough’s evolving streetscape. Regeneration schemes such as Tottenham Hale’s transformation highlight how contemporary architecture can integrate with Haringey’s existing urban fabric.

Planning Permission in Haringey
Haringey’s planning framework balances the need for housing growth with the protection of its historic built environment. The borough operates under the Haringey Local Plan (a series of documents currently being combined into a ‘New Local Plan’) and the London Plan, both of which set out guidelines for housing, sustainability, and design quality. Haringey includes a mix of conservation areas, suburban neighbourhoods, and areas of regeneration, meaning planning policies can vary significantly across the borough.
Planning permission is required for most extensions, new-build projects, major alterations, and significant change-of-use applications, with factors such as building height, density, and environmental impact carefully assessed.
Applications are reviewed by Haringey Council, which considers aspects such as design quality, impact on neighbouring properties, and contribution to the local area. Most London boroughs including Haringey offer pre-application advice that can help identify potential challenges early, improving the chances of planning approval.
Key Considerations for Planning Permission
Full Planning Application – Homeowners will need to apply for full planning permission if they want to undertake any major works including demolishing and building a new house, or works to multiple dwellings. Haringey’s planning policies strongly emphasise context-sensitive design, particularly in conservation areas where proposals must preserve or enhance the historic streetscape. Well-considered designs that complement the borough’s architectural character have a greater chance of approval.
Householder Planning Applications – A streamlined process for homeowners looking to extend or alter a single house (excluding flats or multiple dwellings). In Haringey, this applies to projects such as rear extensions, loft conversions, and outbuildings that exceed Permitted Development (PD) rights. Areas with Article 4 Directions often have additional restrictions, requiring homeowners to secure planning approval even for minor alterations.
Change of Use Applications – If you are converting a property (e.g. turning a former shop into a home), you will need to apply for a Change of Use application. Haringey enforces employment retention policies, particularly in areas such as Wood Green and Tottenham, meaning change-of-use applications are assessed carefully to protect commercial and office spaces.
Basement & Subterranean Developments – Homeowners considering basement excavations or extensions will need to meet structural and environmental requirements. Haringey’s policies require Structural Method Statements and impact assessments to prevent flood risk and damage to neighbouring properties. Applications for basements are assessed cautiously due to the borough’s dense urban environment and high proportion of terraced housing.
With experience of Haringey’s planning system, we provide guidance to maximise development potential while helping you to meet local policies and regulations. Depending on your requirements, we offer project planning advice, project management, feasibility studies, planning applications, and can liaise with planning officers on your behalf.

Heritage & Listed Buildings in Haringey
The term heritage refers to the borough’s broader historical and architectural legacy, encompassing listed buildings, conservation areas, historic streetscapes, and significant sites, many of which are protected through national and local planning policies. Conservation areas are specific geographic zones where additional planning controls apply to preserve the area's overall character and historic value.
Heritage protection in Haringey focuses on preserving the borough’s historic villages, Georgian, Victorian & Edwardian housing, and cultural landmarks, which collectively shape its architectural and cultural identity. Haringey’s heritage assets reflect its history, from its rural origins to urban expansion during the 19th and 20th centuries. The borough is home to over 350 listed buildings, including Georgian townhouses in Highgate, Edwardian villas in Muswell Hill, and Victorian terraces in Crouch End. The borough also contains industrial heritage sites, such as former warehouses and railway buildings, that have been repurposed for modern use while retaining their historic fabric. Any modifications to listed buildings, including internal and external alterations, require Listed Building Consent, making sure changes respect their historical and architectural significance.
Our expertise in heritage-led design can help your historic property remain functional and relevant, balancing conservation with modernisation to meet contemporary needs.
Conservation Areas in Haringey
Haringey has 29 designated conservation areas that are protected to preserve the boroughs architectural and historical heritage. These areas have additional planning controls to maintain their unique character.
Developments in Haringey’s conservation areas are subject to their Conservation Area Character Appraisals and Management Strategies, which outline restrictions on materials, external building alterations, and extensions to preserve the area’s architectural and historic character. Proposals are assessed for their impact on the surrounding streetscape, and applications often require a Heritage Statement to justify design choices. These documents provide detailed guidance on the specific character of each conservation area and are frequently referenced in the assessment of planning applications.
Our team have experience navigating these planning constraints and designing sensitive yet contemporary solutions that integrate modern living requirements with heritage considerations, while achieving high-quality architectural design.

Permitted Development Rights in Haringey
Permitted Development (PD) rights allow homeowners to undertake certain building works without the need for planning permission, provided they meet specific criteria set by national legislation. These rights cover a range of residential improvements, including some single-storey rear extensions, loft conversions, outbuildings, and other alterations. However, Permitted Development rights are subject to limitations and conditions that may vary depending on the property type and location. Flats, maisonettes, and Listed Buildings do not benefit from Permitted Development rights, and properties within conservation areas often have additional constraints. Some homeowners in areas such as Highgate or Muswell Hill may also need to seek trust or committee (e.g. The Highgate Society Planning Committee) approval in order to make any changes to the property, regardless of Permitted Development rights or Planning Approval.
The London Plan explains that Article 4 directions are used by Local Planning Authorities to remove certain permitted development rights in all, or part of, its area.
Haringey’s Approach to Article 4 Directions
Office to Residential (Class E to C3) Restrictions – Haringey has applied Article 4 Directions in key commercial areas like Wood Green, Tottenham, and Crouch End to prevent uncontrolled office-to-residential conversions that could undermine business and employment space.
Conservation Area Protections – In Noel Park, Peabody Cottages, Rookfield Estate and Tower Gardens Conservation Areas, Article 4 Directions remove certain Permitted Development rights to preserve the historic and architectural character. Even minor external alterations, such as changing windows or roofing materials, often require full planning permission.
Suburban Character Preservation – Haringey places a strong emphasis on maintaining the unique character of its residential areas. Large-scale extensions and outbuildings that might be acceptable under Permitted Development in other boroughs may be more restricted in Haringey, particularly where they could impact neighbouring properties or local character. You can check their local plan and conservation area guidelines to see if your property is affected.
Permitted Development in Conservation Areas
Haringey currently only has four Conservation Areas (Noel Park, Peabody Cottages, Rookfield Estate and Tower Gardens) where Article 4 Directions remove Permitted Development allowances. Other Conservation Areas, although they have no Article 4 Directions, are still subject to conservation restrictions within the usual Permitted Development rights.
While some London boroughs impose borough-wide Permitted Development restrictions, Haringey balances conservation with flexibility, allowing many Permitted Development rights in suburban areas while protecting historically significant locations.
Permitted Development Scheme - Concept Massing Model
Key Considerations for Permitted Development in Haringey
Extensions & Alterations – Some single-storey rear extensions, loft conversions, and certain roof alterations may be allowed under Permitted Development, subject to size and design constraints.
Outbuildings & Garden Structures – Some sheds, studios, and home offices can be built under Permitted Development if they remain within height and footprint limits.
Change of Use – Some commercial-to-residential conversions may be possible under Permitted Development but may require prior approval.
Trust Approval – In certain areas, additional approval from estate management trusts or residents' associations is required alongside standard planning permission. This applies to locations such as Highgate, where strict guidelines govern alterations to maintain architectural integrity. Trusts may impose additional restrictions on extensions, window replacements, and even minor external changes, requiring homeowners to seek consent before carrying out work, separate to planning permission or Listed Building Consent.
Our team can assist you to apply for a Lawful Development Certificate (LDC), which provides official confirmation from Haringey Council that the work does not require full planning permission. We guide clients through this process, helping them to comply with relevant criteria and to maximise development potential within permitted allowances.
Sustainability in Haringey
Haringey has set sustainability targets in accordance with both the London Plan and its own Climate Change Action Plan, 2021. The borough’s approach to sustainability focuses on reducing carbon emissions across housing, transport, and commercial developments, while also enhancing biodiversity and improving climate resilience. Haringey has implemented a Carbon Management Plan, targeting net-zero carbon emissions for the council itself by 2027 and for the borough by 2041. Its planning policies push for new developments to incorporate energy-efficient design, low-carbon materials, and urban greening, while older buildings are being retrofitted to improve sustainability.
Haringey is one of London’s most progressive boroughs in district energy networks, with the Energetik heat network supplying low-carbon heating to homes in Tottenham Hale. Additionally, the borough operates a Community Carbon Fund, which reinvests developer contributions into local environmental projects.

Key Sustainability Priorities in Haringey
Carbon Reduction & Net Zero by 2041 - Haringey aims to be a net-zero borough by 2041, with the council aiming to achieve net-zero carbon status by 2027. The borough has introduced a Carbon Offset Fund, which secures contributions from developers unable to meet on-site carbon reduction targets. These funds are reinvested into local decarbonisation projects. New developments must meet zero-carbon standards, integrating passive house design principles, low-carbon heating, and renewable energy technologies.
Energy Efficiency & Retrofit of Existing Homes - Haringey has a high proportion of older homes, many of which are energy inefficient. The council is therefore prioritising retrofit programmes, including insulation, double glazing, and air-source heat pumps to increase the general energy efficiency of the local housing stock. The programmes provide funding and support for homeowners and landlords to upgrade insulation and heating systems while maintaining architectural integrity. The borough is also expanding its Energetik district heat network, which uses low-carbon energy sources to provide heating and hot water to homes and businesses, reducing reliance on gas boilers.
Urban Greening & Biodiversity - Haringey is enhancing urban green spaces to increase biodiversity and improve air quality, in line with the Urban Greening Factor (UGF) standards set by the London Plan. The council is promoting green roofs, living walls, and sustainable drainage systems (SuDS) to reduce flooding and improve climate resilience. Tree planting initiatives have also been introduced with the aim to increase canopy cover and improve public green spaces.
Waste Reduction & Circular Economy - The borough encourages reuse and upcycling initiatives, supporting circular economy principles to minimise construction waste and promote sustainable building practices. Planning policies may require developers to submit Circular Economy Statements, ensuring that materials from demolitions are reused or recycled rather than sent to landfill.
