Planning Approval Secured – Subdivision & Roof Extension - 25A Queens Parade, Friern Barnet Road, N11
We are pleased to confirm that planning approval has been secured for the subdivision of an existing residential maisonette at 25A Queens Parade, Friern Barnet Road, N11 into two self-contained flats, alongside a rear extension and roof alterations.
The scheme was approved by the London Borough of Barnet under reference 25/4699/FUL.
Project Overview
The site comprises a three-storey mixed-use property located within the Friern Barnet Local/Neighbourhood Centre, with commercial use at ground floor and residential accommodation above.
The approved development includes:
First floor rear extension (4.4m depth, full width)
Two rear dormer extensions
Two front rooflights
Subdivision into 2 x 2-bedroom flats (2b3p)
Internal cycle storage (4 spaces)
Car-free development
The proposal provides:
Flat 1 – 2b3p (62.8 sqm)
Flat 2 – 2b3p (70.3 sqm)
Both units meet London Plan minimum space standards following amendments to internal layouts and ceiling heights.
The Planning Context
This site has a complex planning history, including previous refusals for mansard roof extensions.
Rather than pursuing an over-intensive approach, the strategy focused on:
Aligning the roof design with previously approved dormer schemes
Respecting Barnet’s Residential Design Guidance SPD
Ensuring compliance with Policy HOU03 (Residential Conversions)
Meeting London Plan Policy D6 internal space standards
Addressing PTAL and town centre location considerations
The site benefits from PTAL 3 and is located within the Friern Barnet Local Centre, supporting the principle of conversion to flats.
Planning Strategy
This approval demonstrates the importance of:
Reviewing historic refusals carefully
Aligning proposals with previously approved fallback schemes
Amending internal layouts to meet minimum GIA and ceiling height standards
Responding proactively to policy compliance issues during determination
Amendments were made during the application process to ensure the flats met London Plan space standards and minimum 2.5m ceiling height requirements across 75% of the dwelling.
The final scheme was recommended for approval, with officers concluding that the development would:
“provide an acceptable quality of accommodation for future occupiers” delegated report
Design & Technical Resolution
The proposal:
Respects the established mixed-use parade character
Mirrors previously approved extension forms
Avoids adverse impacts on neighbouring amenity
Provides compliant cycle storage
Delivers two dual-aspect flats
Despite the lack of private amenity space, the town centre location was considered acceptable in planning terms.
Outcome
Planning permission was granted by Barnet Council subject to conditions.
The project was overseen by Michael Koutra and led by Architect Monica Theo, whose detailed coordination, creative refinement and policy-led approach were key to navigating the site’s complex planning history and securing approval.
