Mansard Loft Conversions

Your home may be larger than you think! With a mansard loft conversion, you could create additional space in your loft, extending the liveable area of your home, and increasing its overall value.

Why move to a more expensive home when a simple loft conversion to your existing property can give you all the additional space you need. It’s much cheaper than carrying out an extensive home expansion, and certainly less expensive than buying a new home and having to relocate!

Londoners have turned to this unique technique for decades to extend their lofts and make them larger and functional places to live in. If you are interested in a mansard conversion, then here’s all you need to know about the process.

Explaining the Basics

The term “mansard” comes from the French architect François Mansart (1598-1666) of theBeaux Arts School of Architecture in Paris, France. Mansart revived interest in this roofing style, which had been characteristic of French Renaissance architecture, and was used for portions of the Louvre.

This type of loft conversion normally has two angled roofs to the front and rear of a property, with  the roof rafters installed at a 70 degree angle and dormers inserted for additional space.

mansard loft conversion is most commonly found in inner London suburbs. An attractive alternative to the standard dormer conversions, usually created using raised party walls with London stock bricks, they are styled to blend in with existing roof styles and conversions in certain areas.

Can My Loft Be Converted?

The mansard approach to loft conversions is very popular in urban areas across London and other parts of Britain. This style of conversion is also very common in older terraced structures. While suburban properties usually opt for simple, cost effective flat roof dormers, a mansard conversion can be done on almost any type of property, regardless of whether it is a bungalow,  detached, semi-detached or a terraced property.

Do I need Planning Permission?

Under new regulations that came into effect from 1 October 2008, most loft conversions for your home is considered to be permitted development, not requiring an application for planning permission, subject to a number of limits and conditions. Converting your loft with a mansard approach can usually be carried out using permitted development rights, which we can confirm for you during your free consultation.

If you have any doubt in such situations, it is always advisable to seek formal permission. Applying for a Lawful Development certificate or planning permission may feel overwhelming to most homeowners. But don’t worry! Our experts are extremely familiar with the process and can guide you every step of the way.

How Much Will It Cost Me?

The answer to that question is: It depends!

A mansard conversion results in adding a lot of additional living space to the existing loft. This process also requires significant changes to the roof’s structure and shape. As a result, it involves significantly more work to accomplish than other types of loft conversions – like hip-to-gable or dormer conversions.

Because this type of conversion is more involved, the cost to carry it out is higher than other loft conversion approaches. The cost will however vary depending on the size of the property and the shape and height of the existing roof.

How Will Such a Conversion Help Me?

The reasons why property owners may opt to convert their existing lofts are unlimited.

For some homeowners, it is a way to add more space at the top of their homes because of a growing family. Others may need extra space to accommodate friends, extended family or in-laws for long-duration stays. Landlords create loft conversions to maximise their rental income from properties, while developers use conversions to increase the resale value of their property.

You could use loft conversions as an ideal way to:

  • Extend the current loft to give you more living space
  • Add an extra bedroom at the top of the home
  • Use it to build another bathroom or laundry room
  • Convert the loft into a cosy home-office
  • Create more play space for the children

The possibilities are endless!

When you are tight for space, instead of moving home or undertaking a large scale extension, a loft conversion is often the most cost-effective solution.
