Planning and Design

The planning and design phase is crucial to the success of any single storey extension project. Working closely with an architect or designer ensures that your new space not only meets your practical needs but also complements the existing style of your home. Key considerations include maximising natural light, ensuring proper ventilation, and selecting high-quality insulation to create a comfortable living space year-round. It’s essential to ensure your design complies with current building regulations and, where necessary, planning permission requirements. A well-thought-out single storey extension can transform your property, providing a seamless blend of style and functionality while increasing your home’s overall value.

Site Survey and Planning Permission

Before breaking ground on your single storey extension, a thorough site survey is essential. This assessment examines your property’s boundaries, drainage systems, and access points to determine the feasibility of your extension project. Depending on the size and placement of your extension, you may need to apply for planning permission from your local authority. In some cases, your project may fall under permitted development rights, allowing you to proceed without full planning permission. Obtaining a lawful development certificate can provide peace of mind that your extension complies with all necessary regulations, helping to avoid delays and complications as your project progresses.

Extension Project Process

The process of building a single storey extension involves several key stages, each requiring careful coordination and professional expertise. After initial site preparation and groundwork, the project moves through foundation laying, construction of walls, installation of the roof, and finally, the addition of internal finishes and fittings. Throughout the extension project, you’ll work with a team of skilled professionals, including builders, electricians, and plumbers, to ensure every detail meets your expectations. The average cost of a single storey extension can range from £30,000 to £100,000, depending on the size and complexity of the build. By partnering with a reputable contractor, you can ensure your extension is completed on time, within budget, and to the highest standards.

Understanding the Single Storey Extension Cost

One of the most common questions we get is about pricing. The single story extension cost depends on several factors:

1. Size of the Extension: Small vs large single story extensions.
2. Design Complexity: Flat roof, side extension, or custom design.
3. Materials: Steel framing vs traditional methods, finishes, and insulation.
4. Location: Costs can vary slightly across the UK.

Labour costs and professional fees are significant components of the total budget for most single storey extensions. Structural work, overseen by structural engineers, is essential for safety and compliance, and can impact the overall cost. Building control and building regulations approval are required for most single storey extensions, ensuring your project meets all legal and safety standards.

On average, a small single story extension cost will be lower, while larger or custom extensions naturally cost more. We provide upfront quotes so you can plan with confidence.

Living Space and Layout

A single storey extension can dramatically increase your home’s living space, offering endless possibilities for customisation. Whether you prefer an open-plan layout for a modern, airy feel or separate rooms for added privacy, the design can be tailored to suit your lifestyle. Features such as underfloor heating, large windows, and clever storage solutions like loft space can be incorporated to enhance comfort and functionality. With average costs per square metre ranging from £1,500 to £3,000, a well-designed single storey extension is a cost effective way to create the perfect living environment for your family, while also boosting your property’s value and appeal.

Benefits of Steel-Framed Single Story Extensions

Choosing steel-framed extensions offers advantages over traditional brick-and-mortar methods:

• Faster Build Time: Steel structures allow quicker construction with minimal site disruption.
• Long-Term Durability: Resistant to rot, pests, and weather damage.
• Flexible Design Options: Easier to incorporate large windows, open-plan spaces, or contemporary finishes.
• Low Maintenance: Steel requires less upkeep than timber or brick alternatives.
