Loft Conversion vs. Home Extension: Which is Right for Your London Home?
Expanding Your Home in London – The Smart Way
In a city where space is at a premium and property prices continue to soar, extending your home is often far more practical—and cost-effective—than moving. At BuilderHunts LTD, we specialise in helping London homeowners unlock their property’s full potential through expertly designed loft conversions and home extensions.
But which option is the better fit for your home, goals, and budget? This guide breaks down the pros, cons, and key considerations to help you make the right decision.
Why Extend Your Home?
Whether you need a home office, an extra bedroom, or a spacious open-plan kitchen, expanding your current footprint is a smart investment. Both loft conversions and extensions can:
- Increase your property value
- Improve everyday living
- Avoid the stress and cost of moving
Your final choice will depend on your home’s structure, location, and planning limitations.
What Is a Loft Conversion?
A loft conversion transforms your unused attic into a functional living space—commonly used as a bedroom, study, or guest suite. It’s especially popular across London, where many period homes feature generous roof space just waiting to be utilised.
✅ Benefits of a Loft Conversion
- Cost-effective: Generally cheaper than building outwards.
- Adds value: Can increase your home’s worth by up to 20%.
- No loss of garden: Ideal for properties with limited outdoor space.
- Quicker turnaround: Most completed in 6–10 weeks.
⚠️ Things to Consider
- Head height: You’ll need at least 2.2m of clear vertical space.
- Staircase placement: Needs careful planning to avoid disrupting existing layouts.
- Planning rules: Often falls under permitted development, but not always—especially in conservation areas.
What Is a Home Extension?
A home extension involves building outwards—either at the rear, side, or both—to add square footage to your ground floor. This is ideal for creating larger kitchens, open-plan spaces, or additional rooms.
✅ Benefits of a Home Extension
- Custom design: Tailored layout and size to suit your needs.
- Open-plan potential: Great for modernising older London homes.
- Major value boost: Especially in high-demand boroughs.
⚠️ Things to Consider
- Higher costs: More materials, groundwork, and structural input required.
- Outdoor impact: You’ll lose some garden or external space.
- Planning permission: Often required in London—BuilderHunts LTD handles all applications for you.
- Longer build times: Typically takes 10–16 weeks.
Loft Conversion vs. Home Extension: Cost & Suitability

Choose a Loft Conversion if:
- You have unused attic space
- You want to maintain outdoor areas
- Your budget is more limited
- You want a faster return on investment
Choose a Home Extension if:
- You want a larger kitchen or open-plan layout
- Your loft isn’t suitable for conversion
- You need ground-floor accessibility
- You want maximum design freedom
