Navigating planning permission in London can be a complex and time-consuming process. With 32 boroughs — each with its own planning policies, zoning priorities, and conservation restrictions — property owners and developers face a maze of requirements and potential delays. Whether you’re building a rear extension, converting a home into an HMO, or undertaking a new residential development, professional planning advice is essential for a smooth and successful outcome.
At Fraser Bond, we provide strategic planning permission advice in London, helping property owners secure approvals quickly, avoid costly mistakes, and unlock the full value of their assets.
Planning permission is required for:
Converting a single dwelling into an HMO or flats
Major structural changes, including extensions or roof alterations
Changing a building’s use class (e.g. office to residential)
External alterations in conservation areas
New builds and residential redevelopments
Installing or altering shopfronts and signage
Certain minor works may fall under permitted development rights, but these are often restricted in London boroughs or in conservation zones.
Converting properties into Houses in Multiple Occupation (HMOs) or self-contained flats often requires:
Change of use planning applications (C3 to C4 or Sui Generis)
Compliance with space standards, waste management, and parking requirements
Navigating boroughs with Article 4 Directions (removal of permitted development rights)
While some rear extensions and dormers may be allowed under permitted development, many require:
Full planning applications in conservation areas or listed buildings
Design and materials to match local architectural character
Party Wall Agreements and neighbour consultations
We advise developers on:
Pre-application submissions
Affordable housing contributions (Section 106)
Massing, access, and height restrictions
Borough-specific development policies and design codes
If you're changing from retail, office, or industrial to residential or serviced accommodation:
Use class considerations (e.g. E, C3, Sui Generis)
Environmental health, noise, and transport assessments
Loss of employment space restrictions in some boroughs
