Planning Approval for Changes to a Flat in Highgate Conservation Area, Haringey, N6

Project Overview

This project involved carefully considered external changes to a flat on Hornsey Lane Gardens in Haringey, within the Highgate Conservation Area. As part of a full planning application, our architects in Haringey provided architectural and planning services to help secure approval for fenestration alterations and improvements to the existing porch. The proposal included new rear doors and a glazed roof section to the porch, improving natural light, weather protection and the overall functionality of the home.

Design & Planning Strategy

The property is an end-of-terrace building on the corner of Hornsey Lane Gardens and Milton Avenue that had previously been converted into flats across multiple storeys. Because the site sits within the Highgate Conservation Area, the design approach needed to be sensitive to the character of the building and its wider setting.

The approved proposal focused on practical upgrades rather than extensions. To the rear, the opening from the kitchen to the private garden was increased to accommodate new doors, helping create a better connection between the internal space and the garden while also improving daylight. To the front, the existing porch was upgraded with improved materials, a new entrance door and a glazed roof section above, replacing poorer-quality existing elements and creating a more functional and attractive entrance.

From a planning perspective, the scheme was carefully developed to improve the flat without introducing harmful bulk or inappropriate additions. As there was no extension proposed and the external works were limited to fenestration alterations and porch improvements, the design avoided undue impact on neighbouring properties while remaining respectful to the conservation area setting. As experienced planning consultants, we prepared the drawings and supporting information needed to present a clear and well-justified application.

Our team coordinated the architectural drawings, planning statement and supporting documents, submitting a comprehensive package to the council and liaising through the application process.
