The Importance of Planning Permission: What You Need to Know Before Starting Your Project

When it comes to home renovations, extensions, or building a new property, many people focus on the exciting parts of the process like design, interiors, and finishes. However, one of the most crucial and legally required steps is often overlooked, obtaining planning permission. For homeowners and developers across Hampshire and the surrounding areas, this step can make or break a project.

Planning permission is governed by specific legislation that ensures compliance with local planning regulations.

At Lemon Tree Construction, we work with clients in Southampton, Winchester, Portsmouth, and across the South of England, helping them to navigate the complexities of local planning regulations and planning applications. Whether you are looking to build a home extension, convert your loft, or develop a new residential property, understanding the role of planning permission is vital.

In this blog, we explain what planning permission is, when you need it, how the process works, and how choosing an experienced local building contractor can help ensure your project runs smoothly from start to finish.

What is Planning Permission?

Planning permission is the formal approval from your local planning authority that allows you to carry out specific building work. It ensures that a development proposal is safe, complies with building regulations, and does not negatively affect surrounding properties or the environment. Planning applications must align with the local authority’s development plan.

Approval is usually required for larger projects such as:

• Home extensions beyond permitted size limits

• Building a new residential or commercial property

• Loft conversions with structural changes

• Alterations to listed buildings or homes in conservation areas

• Substantial external changes such as balconies or raised decks

If you go ahead without planning permission where it is required, you may be served with an enforcement notice and required to undo the work, a costly and frustrating outcome.

When Do You Need Planning Permission?

Not every building project requires permission. Consulting with a professional can help you decide whether your project requires planning permission. Some smaller improvements fall under what is known as Permitted Development Rights. However, there are many instances where permission is essential. These include:

House Extensions

If your single-storey rear extension extends beyond the rear wall of the original house by more than 3 metres (for a semi-detached home) or 4 metres (for a detached home), you will usually need planning approval. Two-storey extensions, side extensions, and wraparound extensions are even more likely to require consent. It is crucial to submit the correct information and documents as requested by the local authority to ensure your application is validated and considered.

Loft Conversions

Loft conversions that alter the roofline, exceed volume limits (typically 40-50 cubic metres), or include dormers facing the highway may need permission. Loft conversions must meet minimum volume limits and other requirements to avoid the need for planning permission. Submitting the correct information for planning applications is crucial to avoid delays in processing.

New Builds

Any new dwelling, whether a house, bungalow, or flat conversion, will require full planning permission before work can begin.

The typical timescale for processing planning applications is 8 weeks for household and non-major applications, while major planning applications usually take 13 weeks.

Listed Buildings and Conservation Areas

Working on listed buildings or homes in designated conservation areas comes with stricter rules. Even minor alterations like replacing windows or doors may need approval.

Commercial Conversions

Changing a building’s use, for example, from office to residential or retail to restaurant, requires planning permission and may also involve building regulation approval.

If you are in doubt, it is best to consult your local authority or a professional construction company like Lemon Tree Construction, who can guide you through the process.

It is crucial for local planning authorities to respond to applications in a timely manner to ensure efficient processing and maintain communication with all involved parties.

Understanding the Planning Process

The planning application process involves several stages. While it may seem daunting at first, it becomes far easier with expert guidance. The decision making process is crucial for ensuring that applications align with local planning authority guidelines.

Here is an overview:

1. Initial Consultation - We assess your goals and determine whether your plans require permission or fall within permitted development.

2. Design and Planning Drawings - Working with qualified architects and designers, we help produce detailed plans and supporting documents tailored to your local authority’s criteria.

3. Submission of Application - The planning application is submitted to the local council, along with site plans, elevations, and a planning fee. Ensuring all required documents and fees are correctly submitted is crucial for the validation of your application, preventing delays.

4. Public Consultation - The council will consult neighbours and relevant parties. This period typically lasts 8 to 10 weeks.

5. Decision - Your application will either be approved, approved with conditions, or refused. In the case of refusal, there is an option to revise or appeal.

6. Next Steps - Once approved, building work can legally begin. If refused, we can help revise plans and resubmit or appeal.

Why Planning Permission Matters

Complying with planning laws is essential for several reasons:

• Legal Protection: Unauthorised work may lead to fines or enforcement actions.

• Property Value: Homes with fully approved developments are easier to sell and often fetch higher prices.

• Neighbour Relations: Official planning permission ensures that changes respect neighbouring properties and avoid disputes.

• Insurance and Lending: Mortgage lenders and insurers often require proof of compliance for major works.

Failing to get permission can have long-term consequences for your home and finances. Additionally, if an application is refused or conditions are imposed, you have the right to appeal. The appeals process can be lengthy and costly, so seeking professional advice is recommended when deciding whether to appeal a refused application or a condition imposed on a permission.
