Starting a new build in London is an exciting but complex journey. One of the most critical and often misunderstood components is obtaining the correct planning permission. For any homeowner or developer aiming to construct a new property, understanding the ins and outs of planning permission for new build London projects is essential to avoid delays, fines, or the need to tear down non-compliant structures.

Understanding the Basics of Planning Permission in London
Planning permission is legal consent granted by your local authority to carry out certain types of construction or alterations. For new build construction London projects, full planning permission is typically required, especially when creating a new residential dwelling from scratch. Unlike extensions or minor renovations, new builds fall under stricter scrutiny, especially in high-density or heritage-sensitive boroughs.
In many boroughs such as Islington, Hackney or Westminster, homeowners must also factor in conservation area restrictions and listed building status if applicable. These can influence what type of architecture, materials, and scale are permissible.

Full Planning Permission vs Permitted Development
Some minor works can proceed without full permission under what’s called "Permitted Development Rights." However, new builds in London do not fall under permitted development and always require formal application.
This includes:
Submitting scaled architectural drawings
Preparing detailed design and access statements
Providing structural and environmental assessments (e.g. flood risks, energy efficiency)
Approval timelines typically range from 8 to 13 weeks depending on the complexity of the proposal and council efficiency. Here’s where summer construction regulations UK come into play. Council departments tend to process applications quicker during summer due to fewer competing emergencies like winter-related housing repairs.
Tailoring Your Application to Conservation Areas
Many prime London neighbourhoods fall within conservation areas. This status preserves the character of the area and places limitations on height, cladding, roof design, and even window placement. For example, a new build in Hampstead will face stricter scrutiny than one in Croydon.
At TNK Construction, we’ve guided clients through conservation-sensitive planning in boroughs like Richmond and Islington. In fact, our recent Victorian home restoration in Islington was delivered ahead of schedule despite conservation constraints read the full case study.
Key Documents Required for a New Build Application
To obtain planning permission for a new build in London, you typically need to submit the following:
Location plan and site plan
Existing and proposed elevations
Floor plans
Design and access statement
Planning statement
Sustainability and energy statement
Flood risk assessment (if applicable)
Having these documents prepared by professionals ensures your application moves smoothly. TNK Construction’s Initial Assessment Phase includes architectural coordination and planning submission support to ensure nothing is missed.
Summer Build Tip: Apply Early for Faster Approval
One of the often-overlooked tips is that councils tend to approve more quickly in summer. This is largely due to fewer holiday backlogs, better availability of case officers, and fewer public complaints stemming from noisy work in colder months. Summer also provides better ground conditions for the start of works.
By beginning your planning application in May or June, you maximise the chances of being onsite by August. This is ideal for smaller new builds or self-build homes aiming to reach weather-tight status before winter.

Common Pitfalls and How to Avoid Them
Overlooking party wall agreements: In London, many plots are adjacent to other dwellings, requiring legal neighbour notifications.
Underestimating environmental reports: Failing to provide accurate assessments can lead to rejections.
Using outdated drawings: Councils require current, correctly scaled documents.
Ignoring local design guidance: Boroughs have their own architectural rules and preferred materials.
At TNK, we anticipate these hurdles from the start and ensure each file submitted complies with borough-specific guidelines.
