How Do I Extend My Home Without Planning Permission?

Generally, single storey rear extensions must not extend beyond the rear wall of the house by more than eight metres for detached homes, or more than six for other properties styles. Extensions of more than one storey must not extend beyond the rear wall of the original house by more than three metres. How far you can extend your house without planning permission is dependent on the planning department rules, how close your neighbours home is and the type of property. Get in touch with your local department or building control officer for more information.

Should I Choose Extensions or Conservatories?

It’s hard to choose as they both serve different, but very versatile purposes. A house extension will feel like a true part of your home but conservatories will feel more connected to your garden. Extensions offer more privacy but conservatories offer more light. Both have their pros and cons and will look as equally stunning in any style of property.

Do You Postcode Engineer Your Extensions?

Yes, our home extensions come with postcode engineering as standard. Postcode engineering predict the average strength of wind, and other adverse weather in your area. This ensures that your new home extensions is structurally secure and offer total weatherproofing.

 What Roof Do Niddal’s Extensions Have?
