Alvaston Loft Conversions Ltd > Loft Conversions > LOFT TYPE UNDER THE SPOTLIGHT: DORMER LOFT CONVERSIONS

The amount of information to absorb in the initial stages of planning a loft conversion can be quite overwhelming; how much will the work cost? Is my house suitable for a loft conversion? What type of loft conversion is best for my home?

“Wait, there are different types of a loft conversion?” we hear you ask… 

There are four predominant loft conversion styles, the Velux (roof light) loft conversion, dormer loft conversion, hip to gable and mansard loft conversions. We briefly touched base on the varying types of loft conversions in an overview style blog post, but in a bid to make the differences, benefits and processes of each a bit more transparent, we are going to put each loft under the spotlight and highlight the ins and outs in greater detail.  

Our first loft conversion type under the spotlight is the dormer extension

“How much does it cost to put a dormer on the house?”

It’s impossible to put a precise figure on the dormer extension costs, this varies significantly per project, and we price all loft conversions of any type on a case-by-case basis. 

However, what we can say is that dormer loft conversion costs usually start at £19,000 and head upwards from there, how upwards depends on several considerations. One aspect that many people forget to factor in is the price of all the work you must complete AFTER the construction of the dormer loft is over, i.e. the interiors and decoration. 

“Do you need planning permission for a dormer loft conversion?”

Planning permission is not generally required for dormer loft conversions or any loft conversion in the UK, but as with most construction work, there are exceptions. 

If you are extending your loft conversion beyond designated limits or if you live on designated land, such as a National Park or Area of Outstanding Beauty, you will need to acquire planning permission for your local authority. 

We have a planning permission page that explains the limits and conditions for a permitted development loft conversion (permission-free) in great detail, so we recommend heading over to our guide!

“What is a full dormer?”

A dormer loft conversion is an extension that protrudes from the slope of your existing roof, and since they are suitable for almost any home and cheaper than mansard or hip-to-gable lofts, dormer extensions are the most popular type of loft conversion. 

Dormer loft extensions create a great deal of additional floor space and extra headspace in your loft room, as well as creating vertically straight walls and horizontal ceilings within your attic conversion – a welcomed addition when compared to the typically sloped roofs and walls associated with a loft conversion.

“How long does it take to build a dormer loft conversion?”

Alvaston Loft Conversions don’t like to put a definite time-frame on projects until we have been to the site, assessed the current situation and completed all of our drawings and plans. In doing so, we don’t go under or over-estimate too much as many on-site factors could impact the time it takes to complete a dormer loft conversion. 

Alvaston is a well-equipped and experienced specialist loft conversion company, and our average project length is an extremely modest 3 to 4 weeks; so you should be living in your new loft space in no time at all!

“Can I put a dormer in my roof?”

One of the best things about a dormer loft conversion is the versatility; a dormer conversion is a compatible loft extension type for the vast majority of properties. 

The surest way of knowing if your house is eligible for a loft conversion is by having Alvaston’s specialist teams come to your home and carry out a free home survey. We also use the information obtained at your home survey to provide you with an accurate loft conversion quote. 

If you want to do a quick check before we carry out our free survey, there are a few pointers that may indicate if your loft is suitable for any loft extension or conversion:

  • Structure: Is your roof a trussed roof or a traditional cut rafter and purlin roof?
  • Height: The minimum roof height for loft conversion on a trussed roof property is 2.4 to 2.6 metres, and for a traditional roof the minimum roof height is 2.2 metres
  • Chimneys or Services: Chimneys don’t pass through the loft space and do not need relocating
  • Space: Is there adequate space for your new loft room to qualify as a livable space?
  • Watertight: Your roof should have felt lining under the tiles or be fully waterproof

“What is the minimum ceiling height for a loft conversion?”

The minimum ceiling height for a loft conversion depends on what type of loft you have on your property. If you have a traditional roof, the minimum ceiling height requirement is 2.2 metres. But if you have a modern trussed roof, the minimum ceiling height for a loft conversion is slightly higher at 2.4 to 2.6 metres. 

“Do you need neighbours permission for a dormer loft conversion?”

Party Wall Agreements are required for any building work that affects a party wall – a shared wall that separates two homes, usually found in terraced and semi-detached houses. 

Before any work starts, that might affect the party wall, and you should issue a written Party Wall Notice to any neighbours affected by the construction, outlining all of the projected work. You can do this for free using forms found on your local authority websites, and you have one year to begin the work after you have issued your Party Wall Notice. 

More than anything, Party Wall Agreements are courteous to your neighbours and allows you to reach an agreement without any troubles. If your neighbour takes issues with the plans and rejects the agreement for whatever reason, there are avenues to appeal and override the decision – but this doesn’t often happen, so don’t worry!

“Does a dormer add value to a property?”

With space at a premium in most cities and towns and property prices on the incline, proceeding with a loft conversion usually seems the more sensible and financially viable option when you need to expand your home. 

One benefit of a loft conversion, aside from the extra space you will have, is the value that it will add to your property when you do decide it’s time to up sticks and sell your home. All extensions, including dormer loft conversions, hold their weight and then some with regards to adding value to a property.
