Transform Your Home with a Stunning Wandsworth Southfields Double Storey Extension
Homeowners in Wandsworth Southfields often reach a point where their space no longer fits their lifestyle. Growing families need extra bedrooms. Professionals want a spacious home office. Many simply want a larger kitchen and living area for entertaining. Instead of moving, a double storey extension offers a smart way to expand your property while increasing its long-term value.
A Wandsworth Southfields double storey extension allows you to add significant square footage across two levels. You gain flexibility, functionality, and a fresh layout without leaving the neighbourhood you love. In this article, you will learn how this type of extension works, its benefits, design options, planning considerations, and how to make the most of your investment.
Key Takeaways
- A double storey extension adds substantial space across two levels.
- It often provides better value per square metre than single storey builds.
- Planning permission usually applies in Wandsworth.
- Structural integrity and professional design play a critical role.
- A well-executed extension can significantly increase property value.
- Smart layouts and natural light enhance both functionality and appeal.
Why Choose a Double Storey Extension in Southfields?
Southfields remains one of the most desirable areas in Wandsworth. Families appreciate its green spaces, strong community feel, and easy access to central London. Moving to a larger home in the same area often costs far more than extending your current property.
A double storey extension offers:
- Substantial additional living space
- Better return on investment compared to a single storey build
- Improved layout and flow
- Increased property value
- Flexibility for future needs
Instead of adding space in just one area, you transform both ground and first floors. For example, you can create a larger kitchen-diner below and add a master suite or extra bedrooms above.
At Studio20 Architects, we help homeowners reconfigure layouts strategically so every square metre works harder for their family.
Popular Design Ideas for Wandsworth Southfields Double Storey Extensions
Every home in Southfields has its own character, from Edwardian terraces to 1930s semi-detached houses. A well-planned extension complements the original architecture while adding modern functionality.
1. Open-Plan Kitchen and Dining Area
Many homeowners extend at the rear to create a spacious kitchen-dining space. Large slidWandsworthing or bi-fold doors open into the garden, bringing in natural light and creating a strong indoor-outdoor connection. Upstairs, the same footprint allows for an extra bedroom or expanded bathroom.
2. Master Bedroom with En-Suite
A double storey side or rear extension can provide a generous master suite. You gain a walk-in wardrobe, en-suite bathroom, and more privacy. This addition significantly boosts both comfort and resale appeal.
3. Home Office and Guest Room
Remote work has changed how people use their homes. A double storey extension lets you create a dedicated office on the ground floor and a guest bedroom above. You keep work and personal life separate while offering flexibility for visitors.
4. Additional Family Bathroom
Older Southfields properties often have limited bathroom space. Extending upwards allows you to add a second or even third bathroom, reducing morning congestion and increasing practicality for larger families.
Planning Permission and Building Regulations in Wandsworth
Before starting your Wandsworth Southfields double storey extension, you must address planning requirements. In many cases, double storey extensions require full planning permission, especially for rear and side builds.
Key considerations include:
- Impact on neighbouring properties
- Height and depth restrictions
- Distance from boundaries
- Design compatibility with the existing home
You also need to comply with building regulations covering structure, insulation, fire safety, ventilation, and drainage. Working with an experienced architect and builder ensures you meet all legal requirements and avoid delays.
Early consultation with the local planning authority can prevent costly changes later in the project.
Structural Considerations
A double storey extension involves more structural work than a single storey addition. Builders must:
- Assess the existing foundations
- Strengthen supporting walls
- Install steel beams (RSJs) where required
- Ensure proper load distribution
Your contractor will conduct surveys and calculations before construction begins. Solid foundations and correct structural design protect your home’s integrity for years to come.
Budgeting for a Double Storey Extension in Southfields
Costs vary depending on size, design complexity, materials, and finishes. However, a double storey extension often offers better value per square metre than building two separate single storey extensions.
Your budget should include:
- Architectural design fees
- Planning application costs
- Structural engineer fees
- Construction costs
- Interior finishes and fittings
- Contingency fund (usually 10–15%)
High-quality finishes such as bespoke kitchens, underfloor heating, and premium glazing will increase costs but also raise property value.
When comparing costs, consider the price of moving house, including stamp duty, legal fees, and estate agent commissions. Many Southfields homeowners find that extending makes more financial sense.
How a Double Storey Extension Increases Property Value
A well-designed Wandsworth Southfields double storey extension can significantly increase your home’s market appeal. Buyers prioritise space, natural light, and modern layouts.
Adding:
- An extra bedroom
- Additional bathrooms
- A larger kitchen-diner
- Improved flow between living spaces
can dramatically enhance resale potential. In competitive London markets, extra square footage often translates directly into higher sale prices.
Estate agents frequently highlight extended homes as premium listings, especially when the work blends seamlessly with the original structure and maintains architectural harmony.
Design Tips for Maximum Impact
To get the best results from your double storey extension, consider the following tips:
Maximise Natural Light
Install rooflights, large windows, and glazed doors. Light-filled spaces feel larger and more inviting.
Match Materials Carefully
Use bricks and finishes that complement the original property. A cohesive look enhances kerb appeal.
Think Long-Term
Design spaces that adapt to changing needs. A nursery can later become a study or dressing room.
Improve Energy Efficiency
Upgrade insulation, choose energy-efficient glazing, and consider modern heating systems. You reduce energy bills while increasing comfort.
Plan the Layout Strategically
Avoid awkward corridors and wasted space. A smart layout improves daily living and enhances functionality.
Construction Timeline
A typical Wandsworth Southfields double storey extension takes between 4 to 6 months, depending on size and complexity.
The process usually includes:
- Design and planning approval
- Structural calculations
- Groundworks and foundations
- Main structure build
- Roofing and external finishes
- First and second fix internal works
- Final inspections and sign-off
Clear communication between homeowner, architect, and builder ensures the project stays on track.
Common Challenges and How to Avoid Them
Budget Overruns
Set a realistic budget and include a contingency fund.
Planning Delays
Submit accurate drawings and consult professionals before applying.
Disruption During Construction
Work with experienced builders who maintain a clean, organised site and clear schedule.
Poor Design Integration
Choose a design that enhances the existing structure rather than overpowering it.
