Conversion to Flats Approval in Haringey, N22

Project Overview

This approved project at 93 High Road in Haringey involved the conversion of an existing 2/3-bedroom flat at first and second floor level into two separate self-contained flats. The final scheme comprised a one-bedroom flat at first floor level and a two-bedroom split-level flat arranged across the second and third floors.

To unlock the site’s development potential, the proposal also included a second floor rear extension, a rear dormer extension, remodelling of the rear outrigger to a flat roof, the creation of rear roof terraces at first and second floor level, and the provision of refuse and bicycle storage to the rear. The scheme was approved through a full planning application.

As part of the process, our architects in Haringey provided planning-led architectural design and application support, helping to shape a proposal that increased the property’s overall value, improved the internal layout, and created a more efficient residential asset. For developers seeking to intensify use and improve returns from existing buildings, this type of project can offer a strong opportunity where site constraints and planning policy are carefully managed.

Our wider architectural design services are tailored to help property developers assess a site’s potential, refine the scheme, and move through the planning process with clarity.

Design & Planning Strategy

The design strategy focused on making better use of the existing building envelope while introducing additional accommodation in a way that responded to the surrounding context. The second floor rear extension and rear dormer extension were carefully composed to provide additional residential floor area and support the reconfigured flat layouts, while the rear outrigger remodelling helped rationalise the building form and improve the overall appearance of the rear elevation.

The inclusion of roof terraces at first and second floor level added valuable amenity space for future occupants, while the provision of dedicated refuse and cycle storage to the rear helped ensure the development met practical day-to-day operational requirements. These elements are often key considerations in urban flat conversion schemes, particularly where developers are looking to create well-resolved homes that are attractive to the market and capable of securing planning consent.

From a planning perspective, the proposal required careful attention to scale, massing, overlooking, privacy, amenity standards, and the relationship with neighbouring properties. The scheme also needed to demonstrate that the subdivision of the existing upper-floor accommodation into two self-contained flats would create a high-quality residential environment. As experienced planning consultants, we developed and presented the proposal in a way that responded to these issues and supported a positive outcome through the full planning process.

Our team coordinated the preparation of the architectural drawings, planning documentation and supporting material, before submitting a robust application package and liaising with the council throughout the determination period. This planning-led approach is central to how we support developers pursuing planning permission for more complex residential schemes in London.

Project Highlights

• Conversion of an existing 2/3-bedroom upper flat into two separate self-contained flats
• Approved layout comprising a one-bedroom flat and a two-bedroom split-level flat
• Second floor rear extension and rear dormer extension to increase usable residential floor area
• Remodelling of the rear outrigger to a flat roof to improve the rear form of the building
• Creation of rear roof terraces at first and second floor levels
• Provision of dedicated refuse and bicycle storage to the rear
• Planning-led architectural design and full planning application support

Outcome

Full planning permission was secured for the proposed development, allowing the property owner to move forward with a more valuable and better optimised residential scheme.

The approved design demonstrates how an existing building can be reconfigured and extended to create additional units, improve residential quality, and strengthen the commercial potential of a site. For property developers, projects of this nature can offer meaningful uplift when approached with the right balance of design quality, planning strategy and technical understanding.
