Loft Conversion

Different types of bungalow loft conversions 

Bungalows offer great loft conversion potential. They maximise the roof space and create plenty of possibilities. There are four main types of loft conversion that can be appropriate for bungalows. For example: a dormer, hip to gable, Velux, and mansard conversion. Here is a guide to figure out which one if best for your home.  

Types of loft conversions –  

Hip to gable –  

Firstly, a hip to gable loft conversion is where the sloping side of the roof is converted to a vertical gable wall to create more headspace. Bungalows which are semi-detached will often have a hipped roof that slopes at the side. This can be turned into a gable and you are left with a spacious loft and a great amount of head height.  

Benefits of a hip to gable conversion –  

The biggest benefit is the space that you will gain. All this additional room should increase the value of your home, especially if you are adding a bedroom or a bathroom. Also, the staircase from the lower level should be a continuation into the loft. So, this makes the entrance easier to access and uses less living space from the floor below.  

Price – 

Furthermore, the average cost of a hip to gable loft conversion is £40,000 – £50,000.  

Dormer –  

Secondly, dormers create a box shaped structure which is added onto a pitched roof, creating walls that sit at a 90-degree angle to the floor. Also, you can have a dormer in various positions on your roof and you can add more if you want a bigger room inside.  

Price –

So, the average cost of a dormer loft conversion is around – £35,000 – £55,000.  

Velux –  

Velux loft conversions are where the existing roof space is converted into living space without extending the roof structure. There are best for bungalows that already have enough head height. In addition, a roof light or Velux window would be added into the roof to make the new room bright.  

Price –  

Velux is usually the cheapest option because, it requires the least amount of work. Prices can start from £24,000.  

Mansard –  

Finally, a mansard can add a huge amount of space to your loft. A Mansard conversion has a flat roof with a slight fall to allow water to run into the gutter and the face of the Mansard slopes back 72 degrees to create the distinctive design.

What Type Of Loft Conversion Is Best For Your Home

Hip to gable dormer –  

Firstly, hip to gable loft conversions is mostly found on semi-detached properties with an existing hipped roof. It is where the side of the roof is removed off of the sidewall, to maximise the internal head height. Hip to gables is slightly more expensive than a standard dormer conversion, they normally cost 20% more. However, they are the most popular way to convert your loft.  

Cost of project: £40,000 – £65,000

Mansard – 

Mansard loft conversions are typically built at the rear of the house, allowing you to gain additional space in the loft area. However, these conversions usually require roof alterations, which means you would need planning permission.  

Cost of project: £45,000 – £70,000 

Side dormer loft conversion –  

A side dormer is when the hipped roof on the side of the property is built off the sidewall to incorporate additional head height. The side dormer can be built with a flat or pitched roof. If the property is detached, you sometimes can maximise space by constructing a side dormer on both sides of the roof.  

Cost of project: £30,000 – £45,000

Piggyback loft conversion –  

A piggyback loft conversion is formed by raising the existing perimeter walls in brickwork and pitching a new roof, which is stepped back from the front elevation of the property. By raising the bricks and pitching a new roof a large amount of head height is gained, as well as more living space.

Velux –  

A Velux loft conversion is when the shape of the existing roof is retained and Velux windows are installed into the rafters. The rafters will have to be cut depending on the size of the new windows. The inside of the roof space is fitted out to a carefully thought-out design. You will generally not require planning permission to install a Velux window in a loft conversion.   

Cost of project: £20,000 – £30,000

L shape dormer –  

Finally, an L-shaped dormer conversion is where two dormer builds are constructed in a way that they join together. Usually, one dormer will be built on the rear outrigger roof and the other on the main roof, which gives it the L shape.  

Cost of project: £50,000 – £60,000
