For many homeowners, getting planning permission is the most stressful part of a project. You’ve got your dream extension or loft conversion designed, but one refusal from the local council can delay everything or even stop your plans completely.
At Connor Ferris Architects, we’ve helped dozens of Essex homeowners secure planning approval for their extensions, new builds, and renovations. Here are the most common reasons planning applications get refused, and how you can avoid them from the start.
1. Overdevelopment of the Site
Councils often refuse proposals that are considered too large for the plot. This might mean your extension takes up too much garden space, dominates neighbouring homes, or disrupts the area’s character.
How to avoid it:
Work with an architect who understands local design policies. At Connor Ferris Architects, we design with Essex planning guidelines in mind, creating schemes that maximise space without breaching planning limits.
2. Loss of Light or Privacy
If your extension blocks sunlight or overlooks a neighbour’s property, it’s likely to raise objections. Councils prioritise protecting neighbouring amenity — meaning their light, privacy, and views.
How to avoid it:
We use 3D visualisations and sunlight studies to show planners how your design respects neighbouring homes. Subtle design tweaks, like window positioning or stepped facades, can make all the difference.
3. Design Not in Keeping with the Area
Planners expect new developments to complement the character of the surrounding street or village. A design that looks out of place whether too modern or too bulky can trigger a refusal.
How to avoid it:
We specialise in contextual modern design clean, contemporary extensions that still respect traditional Essex architecture. Our designs balance innovation with sensitivity, so your home stands out for the right reasons.
4. Inaccurate or Incomplete Drawings
Applications are frequently rejected because the submitted plans are incomplete or technically inaccurate. Missing elevations, wrong scale drawings, or lack of site context can all cause delays or refusals.
How to avoid it:
Always have your planning drawings prepared by a qualified architect. Our team handles everything from measured surveys to planning statements ensuring your application meets every technical requirement.
5. Breaching Planning Policies
Every council has its own Local Plan and Design Guide, setting out what’s acceptable in terms of height, materials, parking, and green space. Ignoring these policies almost guarantees refusal.
How to avoid it:
We stay up to date with Chelmsford City Council and surrounding Essex authorities’ planning policies. Before submitting anything, we check your proposal against all relevant documents to make sure it stands the best chance of approval.
6. Objections from Neighbours
Neighbour objections can influence planning officers especially if they’re backed by valid planning concerns (like privacy or scale).
How to avoid it:
We recommend talking to your neighbours before submitting plans. Transparency early on can prevent formal objections later. We can also provide visuals to help them understand the design and ease concerns.
7. Poor Quality or Generic Design
A design that feels generic, bulky, or unconsidered can signal to planners that the applicant hasn’t thought about context or detail — two red flags for refusal.
How to avoid it:
An architect-designed scheme always carries more weight. At Connor Ferris Architects, every design is bespoke carefully tailored to your home, your lifestyle, and your planning context.
