What is The Best Loft Conversion For You

Here is a guide to loft conversions to help pick the best one for you and your home. When choosing a project you must take into account the styles, budget, your existing roof structure and any planning restrictions you may face.  

Types of Loft Conversions  

There are four main types of conversions which are: 

  • Dormer 
  • Roof light 
  • Hip-to-gable  
  • Mansard  

Dormer Conversion  

Dormer conversions are one of the best and more popular loft conversion, they provide lots of extra space. A Dormer is an extension that is built on the slop of your roof. There are different types of Domer conversions you should know about such as: 

  • Single dormer 
  • Double dormer 
  • Flat-roofed dormer 
  • Gabled dormer  

Pros and cons of getting a Dormer 

Pros  

  • Suitable for most homes  
  • Less expensive than other conversions  
  • Adds a good amount of extra space 
  • Planning permission isn’t needed in most cases 
  • An option for most that houses that have sloping roofs 

Cons  

  • Not a quick process  
  • More structural changes than most conversions  

Roof Light Loft Conversion 

A roof light conversion is simply your existing loft is retained but rooflights are added. However, after that all you need to do is lay down flooring and add some stairs. Don’t forget about plumbing along with insulation. This is perfect for smaller spaces. 

Pros and cons of a Roof light conversion 

Pros 

  • The cheapest loft conversion  
  • Suitable if you live in a conservation area 
  • Not a lot of structural changes  
  • Least disruptive to the home 

Cons  

  • Less space provided than other conversions 

Hip-To-Gable Loft Conversion 

Hip-to-gable conversions work by extending the sloping roof at the side or your house outwards to create a vertical wall, creating more space. 

Pros and cons of a Hip-to-gable conversion 

Pros 

  • Natural looking  
  • Less expensive than extending outwards 

Cons  

  • More expensive than a dormer  
  • Can only be done on semi-detached or detached houses 
  • Only suits house’s with a sloping side roof 

Mansard Loft Conversion 

A Mansard conversion involves replacing the sloping roof structure with a wall that is almost vertical. The final roof is flat. This project can add a whole additional storey for say. 

Pros and cons of a Mansard conversion 

Pros  

  • A large amount of additional space 
  • Suitable for different types of properties 

Cons  

  • Expensive  
  • Does not look natural  
  • Complex project meaning it could take longer  

Planning Permission & Permitted Development 

Usually when wanting to convert your loft you will not need to do a full planning application as this will come under permitted development rights. In some cases, you will need to apply for planning permission. If you: 

  • Live in a flat or maisonette 
  • Exceed permitted development  
  • Live in a conservation area  

You will need to apply for permission. For your project to be considered as permitted development it must follow these set rules. Here are a few: 

  • Not to build higher than the highest part of the roof. 
  • Not have any dormers or extensions on the roof plane of the principal elevation facing the road. 
  • Be constructed with materials similar in appearance to the existing house. 

There are more rules you will have to follow under permitted development.

Adding a dormer to an existing loft conversion

There are two reasons why people may want to do this: 

  • People buy a house with an existing roofline conversion and decide they want to upgrade the loft accommodation. They might do this to make the space larger, brighter and, perhaps change the interior usage.  
  • Secondly, the loft conversion is planned in two stages to spread the cost. Or because the demand for accommodation at that time is satisfied with a simpler roofline conversion. 

What is a dormer loft conversion? 

A dormer is a box-like structure with vertical walls which come out from the roof slope. They can vary in size and style. In addition, dormers are commonly used to increase the usable space in a loft and to create window openings in the roof.  

Do you need planning permission to add dormers to an existing loft conversion? 

The same planning deliberations will apply to the upgrade just like if you were to start from scratch. If your loft conversion was built under permitted development, you shouldn’t assume that the dormer you’re adding will be as well. So, some points that may make you need planning permission are: 

  • How far the dormer windows project from the roof 
  • Whether the property is listed or in a conservation area.  
  • How much structural change is made to the appearance and height of the existing roof.  
  • The overall size of the loft conversion, the upgrade could make the conversion larger than the original design.  
  • Your neighbours are affected by your dormer. Either by being over shadowed or over looked.  
  • The dormer exceeds 40 square meters on a terraced house or 50 square meters on a semi-detached or detached house.  

Although, not all dormer conversions require planning permission. Your builder or architect will be able to advise you on whether your plans fall within permitted development rights.  

Advantages of adding a dormer –  

Dormer loft conversions are one of the most popular options when it comes to loft conversions. So, here are some advantages of adding them:  

  • They are suitable for almost every type and style of house. 
  • Dormers increase the head height and usable floor space.  
  • You can use any type of window to match the property. You aren’t confined to Velux windows or roof lights.  
  • Could add a small Juliet balcony 

How much would it cost?  

Finally, if you already have an existing loft conversion and you want to add a dormer, you should expect to pay upwards of £5000. However, this all depends on the size, style, and other factors when it comes to a dormer.
