Side Return Extension Cost

A side return extension is an excellent strategy for maximising underused space at the side of your house, transforming it into valuable living space that can enhance your home’s functionality and value. This upgrade is particularly beneficial for terrace houses, which commonly feature narrow side returns that serve little purpose in their original state.

 

Such extensions are a savvy choice not only for their ability to repurpose useless areas but also for the potential to incorporate a new kitchen, elevating your home’s entertainment and living areas. However, navigating the cost of a side return extension can be challenging, given the factors influencing final expenses, such as architect fees, building regulations, and the need for a party wall agreement with neighbours.

 

In this guide, we delve into what homeowners might expect regarding the average cost of a side return extension. Whether you are located in London or outside London, looking to add a single-storey extension or considering a more complex double-storey extension, this article aims to equip you with the essential knowledge to take the next steps.

Introduction to Side Return Extensions

Defining the Side Return Extension

Side return extensions use the narrow gaps found near terraced or semi-detached properties to transform them into valuable, usable space. This approach typically helps square off existing home layouts while breathing new life into dark and underutilised corners of home life.

 

Though an extension might appear minor on paper, its impact on overall proportions in connected rooms such as kitchens can be substantial. By expanding into this space, homeowners can experience more spaciousness, light, and enjoyment in their living spaces.

The Popularity of Side Return Extensions in London

Side return extensions have become an attractive home improvement solution in London for several compelling reasons, including:

 

  • Expanding the living areas: Homeowners can significantly expand their living areas by creating more room for a kitchen or dining space that suits modern living needs.
  • Enhancing natural lighting: By installing features like glass side return extensions or skylights, natural light is brought into interior spaces, making them feel brighter and more welcoming.
  • Enhancing property Value: Installing a side return extension can add great value to a property by increasing its aesthetic and functionality, making it more desirable among potential buyers.

Comprehensive Cost Breakdown of a Side Return Extension

Like any house extension cost, the quality of materials and finishes used, whether a single- or double-storey extension, all impact the price. Geographic location also plays an influential role, with London typically costlier than other parts of the UK.

Here is a detailed breakdown of the costs associated with different types of side extensions:

Type of Side Extension Low Cost High Cost Average Cost
Small, single-storey side return extension cost £30,000 £45,000 £37,500
Small double-storey side return extension cost £45,000 £65,000 £55,000
Side return kitchen extension cost £5,000 £14,000 £9,500
Side return extension cost per m² £1,500 £4,500 £3,000
Glass side return extension cost per m² £3,000

Average Costs of Side Return Extensions

Outside London, costs per square metre can range between £1500 and £2400 per metre; in comparison, London experiences higher costs – reaching up to £4,500 due to factors including increased labour and material costs.

Single-Storey vs Double-Storey Side Extensions

The single-storey extension cost for side extensions is around £30,000 to £45,000, with an estimated average cost of around £37,500. For double-storey extension costs, you’re looking at £45,000 – £65,000 with an approximate average of £55,000.

Kitchen Side Return Extensions

Popular among homeowners looking to add functionality and flow into their kitchen without going the full remodel route, side return kitchen extensions are an economical and straightforward solution ranging from £5,000 to £14,000, typically costing approximately £9,500.

Financial Planning for Your Side Return Extension

Budgeting for Your Side Extension

An extension project requires careful financial preparation to avoid unpleasant surprises in terms of costs. Begin by measuring the area you intend to extend and researching average costs per square metre in order to establish an affordable budget.

Cost Per Square Metre Analysis

When calculating the cost of a side return extension, location plays a crucial role. Outside London, homeowners might expect costs to range between £1,500 and £2,400 per square metre. However, the cost of a side return extension in London, due to higher labour and material costs, is higher – up to £4,500 per square metre. This variance highlights the importance of regional cost considerations in your budgeting process.

Hidden Costs and Considerations

Additional costs are crucial in budgeting for your side extension. Security enhancements such as outdoor lights, CCTV, locks, and alarms might need an electrician or specialist, costing £150-£200 daily.

 

Internal fittings, like shelves or bespoke cupboards, require a carpenter or kitchen fitter, with costs starting at £100 per day and basic cupboards from £100. Opting for second-hand cupboards can save money.

 

Guttering and drainage, vital for water management, could cost around £10 for a water butt and £150 for guttering, often installed by a builder or homeowner. Early planning for these costs ensures a smooth project completion.

Legal and Planning Considerations in Side Extension Costs

Planning Permission and Regulations in London

In London, the scope of your side extension can sometimes fall within Permitted Development rights, eliminating the need for formal planning permission. This concession aims to simplify smaller home improvement projects, making it easier for homeowners to extend their living space.

 

However, even without the need for planning permission, every house extension, including a side return extension, must comply with building regulations. These regulations ensure the safety, energy efficiency, and accessibility of the new structure, covering everything from structural integrity to fire safety. Adherence to these rules is crucial for the legality and long-term success of your project.

The Necessity of a Party Wall Agreement

When planning a side extension, particularly in densely populated areas like London, the party wall agreement becomes significant. If your planned extension involves work on or near a shared boundary, or if it requires digging near a neighbouring building, you will likely need this agreement.

Timeframe and Process of Building a Side Return Extension

Typical Duration for Completing a Side Return Extension

The journey to extend your living space with a side return extension can vary in length, but on average, it takes around 12 weeks to complete. This time can shift depending on the complexity of your project, the size of the extension, and the specific requirements for building work.

Step-by-Step Process Overview

Before the first brick is laid, ensuring you have planning approval and building regulation-friendly plans developed by an architect is essential. Here is a concise guide to the building process:

 

  1. External Construction:
    • With permissions in place and your team ready, the first phase includes site preparation, foundation laying, external walls, and roof construction, and installing windows and doors. Expect to organise scaffolding, skips, and other necessary equipment during this stage.
  2. Interior Work:
    • This phase focuses on reconfiguring the internal space, removing old fixtures, and installing insulation to meet building regulations.
  3. Internal Fit-Out:
    • The internal fit-out includes plastering, flooring, plumbing, and electrical work, setting the stage for new kitchen installations or other specific living space enhancements.
  4. Interior Decor:
    • Finally, the vision comes to life with painting, decoration, and the addition of light fixtures and furniture to match your extension ideas.
  5. Final Inspections:
    • To conclude, address any snagging issues and arrange final inspections to ensure compliance with all safety and building regulations.

Enhancing Your Property with a Side Return Extension

The Value Added to Your Home

An investment in a well-planned and thoughtfully constructed side return extension can significantly increase the value of your property. Expanding living areas or adding rooms not only adds functionality and aesthetic appeal, but can also significantly boost market value.

 

An addition could add as much as 25% value to your home. For instance, an extension on a property valued at £150,000 could see it increase in worth to approximately £190,000. That equates to an approximate return on investment of about 10% over its cost.

 

However, poorly executed projects may fail to add value and could actually detract from it, underscoring the importance of careful planning, selecting suitable materials, and engaging skilled professionals in your extension project to ensure its success.

Side Return Extension as an Investment

Viewing a side return extension as an investment rather than just an expense can shift how you see its value to your property. This investment significantly enhances your living space, improving both the quality of life and the attractiveness of your property on the market.
