Frequently asked questions

Do I need planning permission for a loft conversion in Barnet?

Most loft conversions in Barnet fall under permitted development rights, meaning no planning permission is needed if you stay within certain size and design limits. However, homes in conservation areas or flats may require formal approval. We can advise and handle all applications if needed.

How much does a loft conversion in Barnet cost?

Costs typically range from £30,000 for a simple Velux conversion to £70,000+ for a large mansard or L-shaped dormer. Location, design complexity, and finishes will influence the final price.

How long does a loft conversion take to complete?

A straightforward project, like a Velux or small dormer conversion, usually takes 6-8 weeks. More complex designs may take up to 12 weeks from start to finish.

Will a loft conversion add value to my Barnet home?

Yes. On average, loft conversions add between 15-25% to property value, making them one of the most profitable home improvements in Barnet.

What types of loft conversions work best in Barnet properties?

Many Barnet homes – especially Victorian, Edwardian, and 1930s houses – suit dormer or L-shaped conversions. Semi-detached homes often work well with hip-to-gable designs.

Can my loft be converted if it has a low roof pitch?

Yes, in many cases. We can design dormers or mansard conversions to create the necessary head height while maximising space.

Do you handle building regulations and structural work?

Absolutely. We manage all required approvals, including architectural plans, structural engineering, and compliance with building regulations.

Will I need to move out during the build?

Most of our clients stay in their homes while the loft conversion is being built. We aim to minimise disruption and keep the main living areas usable.

How can I make my loft conversion energy efficient?

We use high-quality insulation, energy-efficient windows, and modern heating/cooling solutions to ensure your loft is comfortable year-round.

Do you offer loft conversions in EN4 and EN5?

Yes – we provide full loft conversion services across Barnet, including postcodes EN4 and EN5, as well as surrounding areas.
