Transform Your Home With a Professional Extension

A house extension is one of the most effective ways to add valuable living space to your property without the upheaval of moving. Whether you need an extra bedroom, a larger kitchen, or an open-plan living area, Rosebrick Developments designs and builds extensions that seamlessly blend with your existing home.

We work throughout Mansfield, Worksop, Nottinghamshire, and surrounding areas, delivering extensions that enhance how you live whilst significantly increasing your property value. From initial design through to final completion, we manage every aspect of your project.

Why Extend Your Home?

Moving house involves estate agent fees, solicitor costs, stamp duty, and the stress of finding somewhere new. A well-designed extension gives you the extra space you need for a fraction of the cost.

The average house extension adds 15-20% to your property value, making it a sound financial investment. Beyond the numbers, you gain a home that works for your family without leaving the area you know and love.

Types of House Extension We Build

Single Storey Extensions Perfect for creating larger ground floor living spaces, single storey extensions are popular for kitchen extensions, dining areas, and garden rooms. They’re typically faster to build and often qualify for permitted development rights, meaning you may not need planning permission.

Double Storey Extensions When you need space on multiple floors, a double storey extension makes economic sense. You’re maximising the footprint by building upwards, creating additional bedrooms upstairs whilst expanding living space below. The cost per square metre is often lower than building two separate single storey extensions.

Rear Extensions The most common type of extension, rear extensions open up your ground floor by extending into your garden. Modern designs often incorporate large bi-fold or sliding doors, flooding your home with natural light and creating that sought-after indoor-outdoor connection.

Side Extensions If you have space to the side of your property, a side extension can add significant width to your home. These work brilliantly for widening narrow hallways, extending kitchens, or creating utility rooms and downstairs WCs.

Wrap-Around Extensions Combining a rear and side extension, wrap-around extensions create substantial additional space. They’re ideal for open-plan kitchen-diner-living areas that modern family life demands.

Our Extension Building Process

1. Initial Consultation We visit your property to discuss your requirements, assess the space, and understand your vision. This is completely free with no obligation.

2. Design Development Working with your brief, we create detailed plans for your extension. We’ll advise on the best approach for your property and budget, whether that’s maximising natural light, matching existing brickwork, or creating statement features.

3. Planning & Building Regulations Many extensions fall under permitted development rights, but where planning permission is needed, we handle the entire application. We also manage all building regulations submissions and inspections.

4. Transparent Quote You receive a comprehensive, itemised quote showing exactly what you’re paying for. No hidden costs, no surprise extras. Once you’re happy, we agree a schedule.

5. Construction Phase Our experienced team completes your extension with minimal disruption to your daily life. We maintain clear communication throughout, keeping you updated on progress.

6. Quality Finish From matching brickwork to seamless internal finishes, we ensure your extension looks like it’s always been part of your home. We don’t finish until you’re completely satisfied.

Do I Need Planning Permission?

Many extensions qualify for permitted development rights, particularly single storey rear extensions up to certain dimensions. However, permitted development rules vary based on location, property type, and proximity to boundaries.

We’ll assess your specific situation during our initial consultation and handle any planning applications needed. Our experience working with local planning authorities across Mansfield, Worksop, and Nottinghamshire means we understand local requirements and can navigate the process efficiently.

How Long Does an Extension Take?

Timescales vary based on the size and complexity of your project. As a rough guide:

A typical single storey rear extension takes 8-12 weeks from groundworks to completion. Double storey extensions generally take 12-16 weeks. These timescales assume planning permission is already in place or not required.

What Does a House Extension Cost?

Extension costs depend on size, specification, and site conditions. During your free consultation, we’ll discuss your budget and show you what’s achievable. Our detailed quotes break down all costs transparently, so you understand exactly where your money goes.

Why Choose Rosebrick for Your Extension?

Local Expertise We’ve built hundreds of extensions across the East Midlands. We understand local building regulations, planning requirements, and architectural styles.

Complete Service From design through to final finishes, we manage everything. You have one point of contact throughout, making the process straightforward.

Quality Materials We use quality materials from established suppliers. Your extension is built to last, not just to meet a price point.

Minimal Disruption We understand you’re living in your home throughout the build. We work efficiently, keep the site tidy, and maintain clear boundaries between the construction zone and your living space.

Extension Design Considerations

Natural Light Modern extensions maximise natural light through carefully positioned windows, roof lights, and glazed doors. The right glazing transforms how a space feels.

Flow Between Spaces Your extension should enhance how your home works. We consider traffic flow, sight lines, and how the new space connects with existing rooms.

External Appearance Whether you want your extension to blend seamlessly or make a contemporary statement, we’ll create a design that works for your property and planning requirements.

Future-Proofing We design with the long term in mind. Under-floor heating pipes laid during construction, wiring for future tech, and robust construction methods all ensure your extension serves you for decades.
