Expanding your home is a great way to create extra space and add value to your property. If you’re considering a home extension in Essex, one of the biggest decisions you’ll face is whether to opt for a single-storey or double-storey extension. Both have their advantages and drawbacks, depending on your budget, needs, and planning constraints. Here’s a breakdown to help you make the best choice.
What is a Single-Storey Extension?
A single-storey extension expands your home at ground level, usually extending out from the rear or side of the property. This type of extension is commonly used to create larger kitchens, open-plan living spaces, or even home offices.
Pros:
- Cost-Effective: Generally cheaper than a double-storey extension.
- Less Disruptive: Construction is usually quicker and causes less disturbance to your daily life.
- More Design Flexibility: Easier to incorporate large windows, bifold doors, and skylights.
- No Impact on Upstairs Layout: Keeps the existing upstairs floor plan intact.
Cons:
- Takes Up Garden Space: Extending outwards reduces your outdoor space.
- Limited Additional Value: While it adds space, a single-storey extension may not add as much property value as a double-storey one.
- Potential Planning Restrictions: Some areas in Essex may have limitations on how far you can extend without permission.
What is a Double-Storey Extension?
A double-storey extension adds extra space to both the ground and first floors, making it ideal for growing families or those looking to significantly increase their living area.
Pros:
- Maximises Space: Offers more room without using as much garden space.
- Adds More Value: Typically increases property value more than a single-storey extension.
- Cost-Effective Per Square Metre: The price per square metre is often lower compared to a single-storey extension.
- Better Investment for Larger Families: Adds extra bedrooms or bathrooms, making it a long-term solution for space needs.
Cons:
- More Expensive: Higher costs due to additional structural work and materials.
- Longer Construction Time: More complex builds take longer and may require temporary relocation.
- Planning Permission Required: Double-storey extensions are more likely to require full planning permission.
- Potential Impact on Neighbours: May reduce light or privacy for neighbouring properties.
Cost Comparison: Single vs. Double-Storey Extensions in Essex
- Single-Storey Extension: Typically costs between £30,000 – £70,000, depending on size and specifications.
- Double-Storey Extension: Usually ranges from £50,000 – £120,000, depending on complexity and materials.
Planning Permission Considerations in Essex
- Permitted Development: Single-storey rear extensions up to 3m (for terraced/semi-detached) or 4m (for detached houses) often fall under permitted development.
- Double-Storey Extensions: Almost always require planning permission due to increased impact on neighbouring properties.
- Local Council Regulations: It’s important to check Essex-specific planning rules before proceeding with a build.
Which One is Right for You?
- Choose a Single-Storey Extension If: You want a cost-effective way to expand your kitchen or living space and don’t need extra bedrooms.
- Opt for a Double-Storey Extension If: You need significant additional space, want to future-proof your home, and have the budget for a larger investment.
