Loft Conversions

There are many reasons why you might want to create a little more living space in your home. Perhaps you are looking to add value to your property. Perhaps you are looking to create a home office or personal space. Or perhaps your family is growing, and your home needs to keep up by expanding.


Whatever the reason, a loft extension offers a smart and practical way to take advantage of the space that you already have.


Our team is highly experienced in dealing with loft conversions, and in creating incredible living spaces.

Permitted development or planning?

  • Typically the maximum internal space would be achieved through permitted development if you own a house which is not in a conservation area or listed.
  • If you own a flat or live in a listed building or conservation area you would need to obtain planning permission where the planning policies typically allow for smaller loft conversions.
  • If you own a large detached house you may achieve the maximum amount of space by applying for planning permission to rebuild the entire roof.

What are the timings?

  • Typically it will take approximately 3 weeks to prepare the relevant planning drawings.
  • Once submitted, the local authority will issue a decision within 9 weeks.
  • Preparing the relevant construction drawings for building control and structural calculations from an engineer will take approximately 1-2 weeks.
  • A typical dormer window would take approximately 5 weeks to complete and a larger conversion with a hip to gable could take up to 6 weeks.

The Loft Conversion Journey

The first and most important step is to decide whether your ideas would be best achieved through either permitted development or planning permission.

Loft conversions can be expensive. Our team’s goal is to help you to get the most out of your budget, and to create something that adds value to both your property and your lifestyle.

There needs to be a minimum distance of 2.2 metres between the top of the joists to the highest point for the space to be usable after the floor has been built-up and the roof insulated.

If you currently have a trussed rafter roof the proposed loft conversion will be slightly more complicated while a traditional roof will be more straightforward to convert.

At this stage we would prepare a full set of existing/proposed elevations and floor plans to submit to your local authority for approval.

Before you start building you will need building control approval to confirm the structural strength of the new floor is sufficient and the stability of the structure is sound.

When it comes to building your loft conversion you can either approach a reputable builder or a company that specialises in loft conversions.
