House Extensions Mansfield – Transform Your Home
Rosebrick Developments has been building house extensions across Mansfield for over 20 years. We understand Mansfield properties inside out, from Victorian terraces in the town centre to modern semis in Ladybrook and everything in between.
Whether you need a single storey kitchen extension, a double storey build to add bedrooms, or a wrap-around extension to completely transform your ground floor, we deliver projects that enhance how you live whilst significantly increasing your property’s value.
Why Mansfield Homeowners Choose Extensions
Property prices in Mansfield have risen steadily, making moving house an expensive option when you factor in estate agent fees, stamp duty, and solicitor costs. A well-designed extension gives you the extra space you need for a fraction of the cost of moving.
The average house extension in Mansfield adds 15-20% to your property’s value, making it a sound financial investment. More importantly, you get to stay in the area you know, keep the kids in their schools, and maintain your local connections.
Types of Extension We Build in Mansfield
Single Storey Extensions
Perfect for creating open-plan kitchen-diners or extending living rooms, single storey extensions are Mansfield’s most popular home improvement. They typically take 8-12 weeks to complete and many qualify for permitted development rights, meaning you may not need planning permission.
We’ve built hundreds of single storey extensions across Mansfield, from modest 3-metre rear extensions to substantial wrap-around builds that completely transform ground floors.
Double Storey Extensions
When you need space on both floors, double storey extensions make economic sense. Build upwards as well as outwards, creating bedrooms upstairs whilst expanding your kitchen or living space below.
Double storey extensions maximise your footprint, delivering more space per pound spent. They’re particularly popular on Mansfield’s semi-detached properties where garden space is limited.
Rear Extensions
The classic Mansfield extension. Extend rearwards into your garden to create a larger kitchen-diner, add a dining area, or simply give your family more breathing room. Modern rear extensions incorporate large bi-fold or sliding doors, flooding your home with natural light.
Side Extensions
If you have space to the side of your property, side extensions add width to your home. They work brilliantly for widening narrow hallways, extending kitchens, or creating utility rooms and downstairs WCs.
Wrap-Around Extensions
Combining rear and side extensions, wrap-arounds create substantial additional space. They’re ideal for creating the large open-plan kitchen-diner-living areas that modern family life demands.
Planning Permission in Mansfield
Many extensions qualify for permitted development rights, particularly single storey rear extensions up to certain dimensions. However, rules vary based on property type, location, and proximity to boundaries.
Mansfield District Council handles planning applications for the area. We have extensive experience working with their planning department and understand what they’re looking for in applications.
Some areas of Mansfield have Article 4 directions or fall within conservation areas, which affect permitted development rights. We’ll assess your specific property during our free consultation and advise on requirements.
