Dormer vs Mansard Loft Conversion: Everything You Need to Know

Loft conversions have become very popular over the last few years, as people look to make the most of their homes. Of all the types of loft conversions out there, dormer and mansard are two of the most popular. But what are they and which one is right for your house? In this guide, we’ll go into the details of dormer and mansard loft conversions, as well as the pros and cons, so you can make an informed decision.

Loft conversion: why it’s worth considering

A loft conversion is a great way to use up space and add value to your property. Turning an unused loft into a room, whether a bedroom, office or extra living space, will increase the comfort and functionality of your home. This will also bring light into areas that would otherwise be dark, making it a bright and airy space. Compared to a traditional extension, a loft conversion is often cheaper and quicker to do with minimal disruption. It is a perfect solution for growing families or those who need more space. A loft conversion can also be considered as a long-term investment, as it increases the value of your property.

What is a dormer loft conversion?

A dormer loft conversion is where you extend the existing roof space upwards to create more headroom and floor space in the loft area. This extension protrudes from the slope of the roof, creating a box-like structure with windows. Dormers come in all shapes and sizes, with the most common being flat roof dormers, gable fronted dormers and L-shaped dormers.

Dormer loft conversion: pros and cons

Dormer loft conversions are practical, as they add headroom and turn lofts into liveable spaces. They are also versatile and can be customised to fit different styles and window layouts, so you can get lots of natural light. They’re also often cheaper than other types of conversions. Another key advantage is the relatively easy and smooth construction process, which is typically faster than more extensive loft alterations, reducing disruption to your home life. Moreover, dormers usually do not require planning permission, as most of the projects fall under permitted development rights.

However, dormers have downsides. Some people may not like the external look and planning permission may be required depending on the design and size, which adds time to the project. And while dormers add space, the usable floor area can still be less than in other types of loft conversions.

What is a mansard loft conversion?

A mansard loft conversion is where you replace one or both of the slopes of the existing roof with a new structure that has a steeply sloping roof and a nearly vertical front wall. This type of conversion gives you the most headroom and floor space and is the biggest addition to the property.

Mansard loft conversion: pros and cons

Mansard conversions are the best option if you want maximum headroom and the most flexible use of loft space. This design gives the most floor space, so it’s perfect for adding new bedrooms, bathrooms or a home office. Mansard conversions also tend to match the existing style of the house and increase the overall look of the property. A well-done mansard conversion can be a good way to invest your money, as it has a high return on investment.

However, these conversions are generally more costly due to the extensive structural work involved. Planning permission may also be necessary, especially if the conversion alters the exterior or affects neighbouring properties. Additionally, construction takes longer and requires meticulous planning to minimise household disruption.

Dormer vs mansard loft conversion: which is right for you?

Now that we’ve looked at the pros and cons of both dormer and mansard loft conversions, you may be wondering which one is best for you. The decision is dependent on many factors, such as your budget, property type, style, local planning regulations etc.

If you want a cost-effective solution, that gives you more space without changing the external appearance of your property, then a dormer loft conversion may be the way to go. If you have the budget for a bigger renovation and want the most living space with a wow factor, then a mansard conversion may be the one for you.

Before you make a decision, it’s best to speak to experienced architects and builders who can visit your property and give you expert advice specific to your needs. They can also help you with the planning permission process, making sure that your loft conversion meets all the regulations.
