Do I Need Planning Permission in Olton or Berkswell Conservation Areas?

Thinking of extending your home in Olton or Berkswell, two of Solihull’s most loved conservation areas? If so, you’re not alone. The rising house prices in Solihull, as revealed by the Office for National Statistics (ONS), are driving more homeowners to consider extending rather than moving. But before you pick up the hammer, understanding the planning permission nuances in conservation areas—particularly Olton conservation area and Berkswell conservation area—is essential.

Why Are Extensions More Popular Than Moving in Solihull?

When looking at the May 2026 local house price breakdowns from the ONS, there’s a clear price gap between Solihull and neighbouring regions. This gap means moving costs and property premiums are becoming increasingly prohibitive for many homeowners. Stamp duty, legal fees, estate agent commissions, and removal costs quickly add thousands to the outlay—without adding any usable living space.

So, an extension—whether a single-storey rear or a two-storey side addition—looks more appealing. However, both come with their own financial and planning hurdles, especially in conservation areas where regulations are tight.

Understanding Conservation Areas: Olton & Berkswell Overview

Conservation areas like Olton and Berkswell are designated to protect the unique architectural and historical character of the neighbourhoods. Consequently, any significant changes to your property’s appearance—from extensions to external alterations—often require more detailed scrutiny by the council.

Here’s what’s crucial for homeowners in these areas:

Stricter Planning Regulations: Permitted development rights may be more restricted or removed entirely.
Design Compatibility: Extensions need to preserve or complement the character and style of the area.
Tree and Landscaping Controls: Many properties have protected trees or green spaces requiring special consent.

Do You Need Planning Permission in Olton or Berkswell Conservation Areas?

Short answer: In most cases, yes—especially for anything beyond minor changes.

Although some small-scale works might qualify as permitted development, the fact that these are conservation areas means many standard rights are curtailed. This is where tools like the Solihull Check over here Council pre-application enquiry come into play, offering a chance to gauge whether your planned extension will need a full planning application or could be done under permitted development rules.

What Exactly Counts as Permitted Development Here?

Single-storey rear extensions up to 3-4 metres depth for terraced/semi-detached homes, slightly more for detached
Extensions not exceeding a certain height limit (often 4 metres for single-storey)
No significant changes visible from the street or landmark-facing sides
Non-habitable outbuildings and sheds under certain size thresholds

However, Olton and Berkswell conservation areas often have Article 4 Directions in place to remove these rights for many properties. That means even small extensions could require a detailed planning application.

Detailed Planning Application: What to Expect

If you must submit a planning application, expect a rigorous review process focusing on:

Design and Materials: Must be in keeping with the original building and conservation guidelines.
Visual Impact: How the extension affects neighbours’ sightlines and local streetscape.
Environmental Impact: Includes trees, boundary treatments, and green space.

You can use the Solihull Council planning application tool to track your submission and understand costs involved.
