Types of Chiswick Loft Conversions

Just about everybody in Chiswick could use some extra space. And a loft conversion is among the best ways you can create more space without spending so much or causing too much distortion. But if you have decided to convert your loft, you need to determine what kind of conversion you will do. Generally, there are three types of Chiswick lofts conversions found in homes across the UK. Each is a bit different, but they all will give you and your family the extra space you have been longing for.

This guide will take you through the types of conversions available so you can decide which one suits your house best.

Types of Loft Conversions to Consider

The most suitable loft conversion for your house is influenced by three things: the type of roof you have, what you want to use your loft for, and your budget. We can generally classify the three types of conversions as internal, dormer, and roof off conversions.

Internal loft conversions are the most affordable as they require minimum building distortion. But the dormers are the most common type as they add more space and involve simple building works. Roof off conversions give homeowners some flexibility, but they are complicated and expensive.

  1. Dormer loft conversions

They involve reshaping the roof to provide greater internal space and height. Mostly dormer conversions are located on the side or rear of the roof, but they can also face towards the front. One can use the extra space as a bedroom, bathroom, or a nursery.

There are different types of dormer conversions, which include single dormer, full-width dormer, side dormer, and l shape dormer.


  • Your walls will remain straight
  • They are a bit cheaper than other conversions

  • They don’t always bring out the best aesthetic appeal
  1. Internal Loft Conversions

Roof light conversions

This involve converting your roof without altering the original shape. Roof lights are best for a higher ceiling which has sufficient head height. The building work consists of creating a roof with sloping windows that point towards the sky fitting to the roof line. Additions include window sets into the existing roof slope.

  1. Roof off loft conversions

These types require removal and rebuilding of the entire roof.

Mansard conversions

They are typically constructed at the rear of your property. They’re similar to a flat roof dormer only that they slope to approximately 70 degrees. Windows on this conversion take on the appearance of small dormers, which adds an aesthetic appeal. They are particularly common in urban areas and terraced housing.

Pre-fabricated loft

It involves replacing the original roof structure with a larger one. The vertical space inside a roof is limited. You’ll have to stay without a roof for a couple of months as it is being replaced and rebuilt.


  • Give more space compared to other types of conversions
