Architectural Design & Planning Permission Services in Barnet

MSK Design Ltd is a Barnet-based architectural practice providing full architectural design, planning and construction consultancy services across the London Borough of Barnet and surrounding areas.

Our studio, located on High Barnet High Street, works with homeowners and developers to deliver successful planning permissions, new-build developments, and sensitive extensions that complement the local character and achieve approval first time.

Several members of our team grew up in Barnet and have seen the borough evolve over the years - from its suburban expansion to the regeneration of key town centres. This personal familiarity gives us a unique understanding of Barnet’s housing character, its planning priorities, and the expectations of local residents and planning officers alike.

Our Planning Expertise in Barnet

We have a proven track record of securing approvals throughout Barnet - from High Barnet and Hadley Wood to Totteridge, East Finchley and Whetstone.


Our experience covers a wide range of planning application types including:

  • Householder Applications for rear, side and roof extensions

  • Full Applications for new-build houses, flat conversions and airspace developments

  • Lawful Development Certificates (LDCs) to confirm permitted development rights for ground floor extensions, loft conversions, and changes of use to established use developments

  • Pre-application advice and design appraisals with Barnet Council’s planning officers

We are highly experienced in designing within conservation areas, including the Hadley Wood, Totteridge, and Hampstead Garden Suburb Conservation Areas — where design quality, materials and contextual response are critical to securing approval.

Our team also has extensive experience working on buildings of architectural interest, including listed and locally listed buildings, where heritage considerations, proportion and material selection are paramount. Our work has also been commended by Barnet’s Urban Design Officer and local councillors at planning committee for our sensitive yet contemporary approach to design to a prominent Art Deco building in North Finchley, which demonstrated how modern interventions can respectfully complement historic fabric.

Our familiarity with the Barnet Local Plan (2024), London Plan policies, and the Council’s Residential Design Guidance SPD ensures each proposal is well-founded in planning policy and design rationale.

In practice, planning outcomes in Barnet often depend not only on compliance, but on how proposals are presented, justified and evidenced. We regularly advise clients where schemes sit within nuanced areas of policy interpretation, particularly in relation to permitted development rights, lawful development certificates and changes of use.

Where clarification of interpretation is required, we engage constructively and professionally to ensure applications are assessed fairly and on their full planning merits.

Architectural Character of Barnet

The London Borough of Barnet is one of North London’s most architecturally varied areas. Its housing stock ranges from Victorian terraces in East Finchley, to interwar semis in Friern Barnet, and large detached homes in Totteridge and Hadley Wood.

Many plots feature generous gardens and roof space potential, making Barnet particularly suitable for extensions, loft conversions and airspace developments.

At MSK Design Ltd, we design each project with sensitivity to its context — balancing character and proportion while optimising internal layouts and energy performance.

Planning Permission in Barnet

Barnet Council handles one of London’s highest volumes of planning applications, and understanding local procedures is essential.

Strategic Preparation in Barnet

In our experience, successful applications in Barnet require early assessment of:

  • Residential Design Guidance SPD compliance

  • Suburban character and streetscape rhythm

  • Neighbouring amenity impact

  • Green Belt and conservation considerations

  • Permitted development interpretation

  • Planning precedent within the locality

We prepare submissions with these factors addressed upfront - reducing risk of delay or avoidable refusal.

Planning routes

We assist clients through every stage of the planning process, from early feasibility to full design and submission via the Planning Portal.

Typical planning routes in Barnet include:

  • Householder extensions within or outside permitted development limits

  • Change of use or subdivision of large houses into flats

  • New-build homes or redevelopment of existing plots

  • Airspace additions creating new dwellings above existing buildings

We prepare full Design and Access Statements, Heritage Impact Assessments, and Energy Statements where required, ensuring submissions are robust and policy-compliant.

Navigating Policy Interpretation in Barnet

Barnet’s planning decisions are shaped not only by written policy but by its application in context. Our role extends beyond drawing preparation - we advise on planning risk, interpretation of permitted development rights, and the strategic positioning of applications to maximise prospects of approval.

This is particularly relevant for:

  • Subdivision of dwellings

  • New build dwellings and mixed use developments

  • HMO proposals

  • Residential extensions

  • Roof enlargements

  • Airspace development

  • Prior approval schemes

Where necessary, we support clients through resubmissions and appeals with robust, policy-led argumentation.

Conservation Areas and Green Belt Design

Barnet includes over a dozen Conservation Areas and significant Green Belt land, including Monken Hadley, Totteridge, and Hampstead Garden Suburb. Projects within these locations often require careful justification of design character, materials and scale.

Our team has extensive experience in preparing context-driven proposals that meet heritage and landscape policy requirements while achieving modern, functional living spaces.

Schemes within Barnet’s Green Belt and Conservation Areas require careful justification of scale, openness and design quality. We prepare clear planning narratives to demonstrate compliance with national and local policy tests, ensuring proposals are defensible and well-reasoned.

Recent examples include Cottage Farm, Galley Lane, Bruce Road, and several dwellings local to us in EN5, as well as commercial units along Finchley Road and prime residential developments across Winnington Avenue, Courtney Avenue and The Bishops Avenue. Each scheme demonstrates our ability to balance architectural ambition with planning sensitivity in Barnet’s most valued settings.

Barnet’s Architectural Heritage

Barnet’s built environment tells a story from medieval origins around High Barnet to twentieth-century suburban expansion. This blend of historic and contemporary fabric provides opportunities for contextual yet innovative design.

At MSK Design Ltd, we respect the area’s architectural heritage and planning context while delivering schemes that incorporate sustainability, efficiency, and modern detailing.
