Planning Consultant in Barnet | Architectural Design & Planning Applications

AY Planning & Construction Consultants provide expert planning application, architectural design, and building regulation services across the London Borough of Barnet, including Finchley, Hendon, Edgware, Barnet town centre, East Barnet, New Barnet, Whetstone, Totteridge, and Mill Hill.

Barnet is one of London's largest residential boroughs, with a predominantly suburban character and a high proportion of detached and semi-detached family homes — making it one of the most active boroughs in London for residential extensions, loft conversions, and new build development. Our team understands the borough's planning policies and design expectations in detail, helping clients achieve the results they're looking for.

Planning Applications in Barnet

Barnet Council takes a consistent and policy-driven approach to planning decisions, with strong emphasis on protecting residential amenity, maintaining local character, and ensuring that new development respects the scale and design of surrounding properties.

Understanding these policies — and designing around them from the outset — is the key to achieving planning approval in Barnet without unnecessary delays or revisions. Our team has extensive experience preparing applications that meet Barnet's requirements first time.

Our planning services in Barnet include:

•    House extensions — single storey, double storey and side returns

•    Loft conversions including hip-to-gable and rear dormers

•    Garage conversions and ancillary structures

•    New build residential development on infill and garden plots

•    Change of use applications

•    HMO and Article 4 direction applications

•    Certificates of Lawful Development

•    Conservation area applications in areas such as Totteridge and Mill Hill

Our ~90% planning application success rate across 200+ completed London projects reflects the thoroughness and strategic thinking we bring to every instruction.

Architectural Design in Barnet

Barnet's residential streets have a strong suburban identity that planning policy works hard to protect. Successful architectural design in this context means creating proposals that enhance the property and meet the client's needs while sitting comfortably within the established street scene.

Our architectural team designs with these constraints in mind from day one, producing planning drawings and supporting documentation that present proposals positively and give every application the best possible chance of approval. We work on everything from modest single-storey extensions to larger residential development schemes.

Building Regulation Drawings in Barnet

Our building regulation drawing service provides fully coordinated, technically detailed packages for projects across Barnet. We work alongside structural engineers and cover all relevant regulations including fire safety, thermal performance, drainage, and accessibility — producing documentation that is ready for Building Control submission and construction use.

Clear, detailed building regulation drawings reduce uncertainty on site, speed up Building Control approval, and help contractors deliver the project accurately and efficiently.
