Why Choose a Single Storey Extension?

Cost-Effective Space Single storey extensions offer excellent value per square metre. Without the complexity and cost of building upwards, you get more space for your budget.

Faster Build Times Typical single storey extensions take 8-12 weeks from groundworks to completion, meaning less disruption to your daily life compared to larger projects.

Permitted Development Many single storey rear extensions qualify for permitted development rights, allowing you to extend without formal planning permission. This saves time and removes uncertainty from the process.

Natural Light Single storey extensions excel at bringing natural light into your home. Large glazed doors, roof lights, and carefully positioned windows create bright, welcoming spaces you’ll want to spend time in.

Popular Single Storey Extension Designs

Kitchen Extensions The most common single storey extension, kitchen extensions create the space modern cooking and family life demands. Open up your kitchen, add an island, create a dining area, or incorporate a snug zone for the kids.

Kitchen-Diner Extensions Knock through your existing kitchen and dining room, then extend rearwards to create a spacious open-plan kitchen-diner. This is the single most transformative extension for family homes.

Garden Rooms Create a light-filled space that connects your home to your garden. Perfect for home offices, playrooms, or simply a relaxing space to enjoy garden views year-round.

Living Space Extensions Extend your lounge or living room to create a more generous entertaining space, add a reading area, or simply give your family room to breathe.

Utility & Boot Room Extensions Side extensions work brilliantly for utility rooms, boot rooms, and downstairs WCs, freeing up valuable space elsewhere in your home.

Design Features That Work

Bi-Fold & Sliding Doors Large glazed doors blur the boundary between inside and outside, flooding your extension with light whilst providing easy garden access.

Roof Lights Velux windows or structural glass roofs bring light from above, particularly effective in extensions where side windows aren’t possible.

Vaulted Ceilings Creating a vaulted or cathedral ceiling adds drama and spaciousness to your extension, making the room feel significantly larger.

Under-Floor Heating Single storey extensions are ideal for under-floor heating. Without radiators taking up wall space, you gain a more comfortable, energy-efficient heating solution with complete design freedom.

Permitted Development Rights

Under permitted development, you can typically extend up to 6 metres from the rear wall of a detached house, or 3 metres for other properties. However, rules vary based on location, conservation areas, and Article 4 directions.

We’ll assess your property during our free consultation and confirm whether your planned extension qualifies for permitted development or requires planning permission.

The Build Process

Week 1-2: Groundworks We prepare foundations, which typically involve digging trenches, laying concrete, and installing drainage and services.

Week 3-4: Structure The walls go up, the roof structure is installed, and the extension starts taking shape. You’ll see rapid progress during this phase.

Week 5-6: First Fix Electricians and plumbers install cables, pipes, and first-fix elements before the walls are plastered.

Week 7-8: Finishing Plastering, decorating, flooring, and final finishes transform the shell into a beautiful room.

Week 9-10: Second Fix & Snagging Final electrical fittings, kitchen installation if applicable, and addressing any minor issues before handover.

Connecting to Your Existing Home

The key to successful extensions is creating seamless flow between new and existing spaces. We carefully consider:

• Floor levels and thresholds
• Matching existing architectural details
• Continuity of flooring where appropriate
• Sight lines through your home
• How natural light affects both new and existing rooms

What Does a Single Storey Extension Cost?

Costs vary significantly based on size, specification, and site conditions. A basic single storey extension might start from £1,500-£2,000 per square metre, whilst high-specification builds with premium materials cost more.
