Homeowners in Wandsworth Putney Heath often reach a point where their current space no longer fits their lifestyle. Instead of moving, many choose to expand upward and outward with a double storey extension. This approach not only increases living space but also enhances property value and functionality.
“Did You Know? A double storey extension can increase your property value by up to 20%, depending on design quality and location. This makes it one of the most impactful home improvement projects you can undertake.”
A double storey extension offers a practical way to add multiple rooms while maintaining outdoor space. Whether you want extra bedrooms, a larger kitchen, or a home office, this type of extension delivers flexibility and long-term benefits.
Key Takeaways
- A double storey extension doubles your space without doubling the footprint.
- It offers better value per square metre than a single storey extension.
- Proper planning permission and building regulations are essential.
- Smart design enhances both functionality and visual appeal.
- Energy-efficient features reduce long-term costs.
- Choosing the right builder ensures a smooth project.
- The extension can significantly boost property value.
Why Choose a Double Storey Extension in Putney Heath?
A double storey extension provides more value compared to a single storey addition. You build on the same footprint but gain double the space. This makes it cost-effective per square metre and highly efficient.
In Putney Heath, where property prices remain high, expanding your current home often makes more sense than buying a larger one. You avoid stamp duty, moving costs, and the stress of relocation.
Many families use the ground floor for open-plan living areas while reserving the upper level for bedrooms or private spaces. This layout improves both comfort and functionality. Studio20 Architects help homeowners design layouts that optimise space without compromising style.
Planning Permission and Local Regulations
Before starting your project, you must check planning permission requirements. Some extensions fall under permitted development rights, but this depends on factors like size, height, and location.
Homes in conservation areas or with special designations may require stricter approvals. Always consult with your local council or a professional architect to ensure compliance.
You should also consider building regulations. These rules ensure structural safety, energy efficiency, fire protection, and proper ventilation. Skipping this step can lead to costly corrections later.
Design Ideas for a Stunning Double Storey Extension
A well-designed extension blends with your existing home while adding a fresh and modern feel. Here are some popular ideas:
Open-Plan Living Area
Many homeowners choose to extend the kitchen and dining area on the ground floor. Large sliding doors or bi-fold doors can connect indoor and outdoor spaces, creating a bright and airy atmosphere.
Additional Bedrooms
The upper level can house extra bedrooms or a master suite with an en-suite bathroom. This setup works well for growing families or those who frequently host guests.
Home Office Space
With remote work becoming more common, a dedicated office space has become essential. A double storey extension allows you to include a quiet and productive workspace.
Natural Light Features
Incorporate skylights, large windows, and glass panels to bring in natural light. This not only enhances aesthetics but also improves mood and energy efficiency.
Cost Considerations
The cost of a double storey extension in Wandsworth Putney Heath varies based on size, materials, and design complexity. On average, you can expect higher upfront costs compared to a single storey extension, but the cost per square metre remains lower.
Key cost factors include:
- Architectural design and planning fees
- Construction materials and labour
- Structural changes to the existing building
- Interior finishes and fittings
Setting a clear budget and working with experienced professionals helps you avoid unexpected expenses.
Choosing the Right Builder
Selecting a skilled builder plays a crucial role in the success of your project. Look for professionals with experience in double storey extensions and a strong portfolio of completed work.
Check reviews, request references, and ensure they provide a clear timeline and cost breakdown. A good builder communicates openly and keeps the project on track. Studio20 Architects work closely with trusted builders to ensure a smooth construction process.
Maximising Property Value
A well-executed double storey extension can significantly increase your home’s market value. Buyers often prefer homes with extra bedrooms, modern kitchens, and flexible living spaces.
In areas like Putney Heath, where space remains a premium, extensions can offer a strong return on investment. Even if you don’t plan to sell soon, the added comfort and functionality make it worthwhile.
Energy Efficiency and Sustainability
Modern extensions focus on energy efficiency. You can incorporate insulation, double glazing, and energy-efficient heating systems to reduce utility bills.
Solar panels, underfloor heating, and smart home technology can further improve sustainability. These features not only lower energy consumption but also appeal to future buyers.
Common Challenges and How to Handle Them
Every construction project comes with challenges, but proper planning helps you manage them effectively.
Budget Overruns
Unexpected costs can arise due to structural issues or design changes. Keep a contingency fund of around 10–15% to handle surprises.
