Planning Permission FAQs

FAQs

Comprehensive Extension Plans For Your Home

Discover everything you need to know about extension plans, from planning permission to building regulations and costs. Surv Essex provides fully compliant plans tailored to your needs.

What are extension plans?

Extension plans are architectural drawings detailing the layout, size, and design of a proposed extension. These include site plans, floor layouts, and elevations, ensuring compliance with local planning and building regulations. Learn more about our planning drawings services.

Why are extension plans important?

Extension plans ensure your project aligns with planning regulations, minimizing the risk of delays. They provide clarity for contractors and help secure approval from local councils. Explore our guide on planning permission for extensions.

What is included in a set of extension plans?

A comprehensive set includes:
  • Site layout plans: Detailing the position of the property.
  • Floor plans: Showing internal layouts.
  • Elevations: External views from all sides.
  • Structural drawings: If required, for compliance.
Check out our building regulations plans.

Do I need planning permission for an extension?

Planning permission is required for most extensions that exceed permitted development rights. For example:
  • Single-storey extensions longer than 6m for semi-detached or 8m for detached homes.
  • Multi-storey extensions.
Learn more about the rules for when planning permission is required.

How much does it cost to create extension plans?

The cost depends on the project's complexity. At Surv Essex, our prices start at £550 for professionally drawn planning documents. Building regulations plans are available as an additional service. Get details on our affordable planning services.

Can I draw my own extension plans?

While it’s possible to create your own plans, professional drawings ensure accuracy and compliance with planning and building regulations. Mistakes in DIY plans can result in costly delays. Discover why professionally drawn extension plans are the smarter choice.

What size extension can I build without planning permission?

Under Permitted Development rights, you can typically build:
  • Single-storey rear extensions up to 6m for semi-detached and 8m for detached houses.
  • Side extensions under half the width of the original house.
Learn more about extensions that don’t need planning permission.

What are planning drawings for extensions?

Planning drawings are essential architectural documents submitted to councils for extension approvals. They include:
  • Floor layouts.
  • Elevations.
  • Site plans.
Discover more about required planning drawings.

What are building regulations plans?

Building regulations plans detail the technical aspects of your extension, such as structural integrity, insulation, and fire safety. These ensure your extension is built to legal standards. Explore our building regulations services.

How long does it take to create extension plans?

At Surv Essex, we deliver fully compliant planning drawings within 5 working days. Building regulations plans take an additional 3–7 days, depending on complexity. Check our fast planning services for more details.

How do extension plans add value to my property?

Well-designed extensions can increase your property value significantly. For example, adding a bedroom or increasing usable living space often boosts resale value by 10–15%. Learn how to make your extension plans work with our expert services.

What is the difference between extension plans and house extension drawings?

Extension plans refer to a complete set of design documents needed for planning and construction. House extension drawings, on the other hand, often focus on detailed layouts for the build phase. Learn about our planning drawings services.

Do I need both planning drawings and building regulations plans?

Yes, both are often required. Planning drawings are for council approval, while building regulations plans ensure the extension meets safety and technical standards. Explore our building regulations services.

What types of extensions are eligible for Permitted Development?

Eligible extensions include:
  • Single-storey rear extensions within size limits.
  • Side extensions less than 50% of the width of the original house.
Extensions in conservation areas or exceeding these limits typically require planning permission. Learn more about Permitted Development rules.

What materials are typically used for house extensions?

Common materials include:
  • Brick and blockwork: Durable and consistent with the main house.
  • Timber frames: Cost-effective and eco-friendly.
  • Glass panels: Modern designs for maximizing natural light.
Read more about extension materials in our conservatory planning guide.

Can extension plans include loft conversions?

Yes, extension plans can incorporate loft conversions, especially when adding multiple stories or maximizing space. These are great for creating additional bedrooms or offices. Learn more about our loft conversion plans.

How do I start the extension planning process?

The process starts with:
  1. A consultation to discuss your goals and budget.
  2. A 3D laser survey of your property.
  3. Drafting extension plans for council submission.
Get started with our planning drawing services.

What are common challenges in designing extension plans?

Challenges include:
  • Site constraints such as small plots or irregular shapes.
  • Planning restrictions in conservation areas.
  • Balancing ambitious designs with tight budgets.
Overcome these challenges with our expert design solutions.

How does the design affect the overall cost of the extension?

Key factors influencing cost include:
  • Complexity: Multi-story extensions require additional structural work.
  • Materials: High-end options like glass or steel increase costs.
  • Labour: Detailed designs may take longer to execute.
Explore cost-effective design options with our extension plans services.
