Types of Loft Conversions

Velux Conversions

One of the keys to making a loft conversion look good without it costing the earth is to use windows built into the slope of the roof.

Velux double glazed roof windows are built to withstand the hardest elements and are the finest available

Rear Dormer

All new loft conversions need maximum walking space inside. This is often achieved by adding a projection called a Dormer.

We tailor the design of the dormer to your particular needs and create the utmost space for an ensuite bathroom or bedroom etc.

Hip to Gable

Some “Hip Ended” roofs may benefit from a “Hip Gable” conversion rather than a side dormer.

Our qualified surveyor who will illustrate the difference can help you make your informed decision on this.

Do I need planning permission for a loft conversion?

Most loft conversions do not need planning permission, however they will require building regulations approval.

You would however need planning permission if your drawings exceed the sizes that come under building regulations only rule.

If you look at the Planning portal web site there is all the information you can read up on.

How much does a loft conversion cost?

This is a hard Question to put an accurate answer too as obviously all houses are different and would need to be seen to give accurate price.

Based on normal 5-6 m wide mid terrace house a rear full loft conversion would normally be around £30,000 finished.

A hip to gable loft conversion can range between £40,000 – £45,000 depending on size of house.

A Velux only loft conversion with no dormers would be £20,000 upwards again depending on sizes.

How long does a loft conversion take?
We would allow around 6-8 weeks depending on the specific build requirements.
How long do Loft conversion building regulations approval take?

Once the council have your drawings and they are registered with building control it will take 5 working days before you could start the works.

Can we live in the house while loft conversion takes place?

Yes 100% you can.

We recommend having all the loft built from above even including plaster work and the breakthrough for staircase.  This keeps dust down to a minimum, then its around a week for completion.

What are the payments process for Loft conversions?

We always recommend on a stage payment programme.

This schedule is payment in installments on completion of each stage.

This way you can see what is being paid for and everyone is happy to move to next stage.

How much height will I need for a loft conversion?

On average you’ll need around 2.2m clear head hight to be able to convert your loft conversion.

Can I have a loft conversion if I have a low roof?

If you really want to convert your loft space and you don’t have 2.2m to start with there is a couple of alternatives.

There is a possibility that you could raise your roof but would need planning permission to do this.

The 2nd option is that you could lower the existing ceilings in the house, we have done this a few times but as warning this is a big job and normally requires the customer to not live in the property whilst this work is in progress.
