Loft Conversion Vs Extension – Which is Best?

When looking to add extra space to your home, two popular options are a loft conversion or a house extension. Both can significantly enhance your living space and add value to your property, but which one is the better choice? The decision depends on several factors, including budget, space requirements, planning permissions, and overall impact on your home. Here’s a comparison to help you decide.

Space and Usability

  • Loft Conversion: Utilises existing space by transforming an unused loft into a functional room, such as a bedroom, home office, or playroom.
  • House Extension: Expands the ground floor or upper levels of your home, creating larger open-plan living areas or additional rooms.

Cost Comparison

  • Loft Conversion: Generally more affordable, with costs starting from £20,000 to £50,000, depending on the type (Velux, dormer, hip-to-gable, or mansard).
  • House Extension: More expensive, with prices typically ranging from £30,000 to £100,000+, influenced by size, materials, and complexity.

Planning Permission and Regulations

  • Loft Conversion: Often falls under permitted development rights, meaning planning permission is not required unless major structural changes are involved.
  • House Extension: May require planning permission, especially for larger or double-storey extensions, and must comply with building regulations.

Disruption and Build Time

  • Loft Conversion: Less disruptive, as work is contained within the loft space; typically completed within 6–12 weeks.
  • House Extension: Can be disruptive due to groundwork and structural changes; usually takes 12–24 weeks.

Value Added to Your Home

  • Loft Conversion: Can increase property value by 15–20%, especially if an extra bedroom is added.
  • House Extension: Can boost home value by 10–25%, depending on size and quality of the extension.

Best for Your Needs

Choose a loft conversion if:

  • You need an additional bedroom or office.
  • You want to increase space without losing garden area.
  • You prefer a cost-effective and quicker option.

Choose a house extension if:

  • You need a larger kitchen, dining area, or extra living space.
  • You have sufficient outdoor space to extend.
  • You’re willing to invest in a long-term structural change.

Both options can enhance your home, but the right choice depends on your space requirements, budget, and long-term goals. If you’re unsure, speak to an expert for professional advice on what will work best for your property.
