At RISE Design Studio, we believe your home should grow with you - transforming into a space that not only meets your current needs but also fulfils your aspirations for the future. A double-storey extension is one of the most effective ways to expand your home, balancing form, function, and value. It’s not just a building project; it’s an investment in your lifestyle and the future of your property.
Imagine doubling the usable space in your London home—creating opportunities for open-plan living, extra bedrooms, or even a sunlit studio for your creative pursuits. The beauty of a double-storey extension lies in its cost-efficiency. By sharing the expenses of foundations and roofing between two levels, the cost per square metre is often significantly lower than building two separate single-storey structures.
In 2024, the typical cost of a double-storey extension in London ranges from £2,700 to £4,600 per square metre, depending on your choice of materials, finishes, and the complexity of the design. While the upfront investment is substantial, the long-term benefits - increased property value and enhanced quality of living - are well worth it.
A double-storey extension is more than just adding space; it’s about transforming how your home works for you. Here’s why it could be the perfect choice:
While the construction phase accounts for the majority of your budget, other factors also influence the overall investment:
London’s diverse housing stock - from detached homes to terraced properties - means that double-storey extensions can be adapted to fit a range of property types. However, navigating planning policies is often essential, particularly for rear or side extensions. Planning authorities often require extensions to remain “subservient” to the original building, making thoughtful design crucial.
For example, if your home already has a single-storey extension with adequate foundations, building upwards can be a cost-effective solution. Alternatively, a new two-storey addition opens up endless opportunities for bespoke layouts and striking features.
Creating a double-storey extension is both a creative and technical endeavour. At RISE Design Studio, we combine precision, sustainability, and craftsmanship to deliver spaces that truly reflect your vision. From the initial concept to the final build, we guide you through every step of the process, ensuring clarity and confidence throughout your project.
Using advanced 3D modelling and virtual reality tools, we help you visualise your new space before any construction begins. This not only minimises risks but also ensures the finished result aligns perfectly with your expectations. Our dedication to sustainable architecture ensures your extension will be energy-efficient, environmentally conscious, and beautifully designed.
Taking the leap to build a double-storey extension is about more than just creating extra space—it’s a chance to reimagine your home’s potential. Whether your priority is adding functionality, enhancing aesthetics, or increasing sustainability, the possibilities are as exciting as they are transformative.
