What are the most common types of loft extension?

One of the most common kind of conversion in London is the Dormer extension which you will often see on Victorian Terraces. This involves raising one side of a sloped roof and will not require any planning permission. A dormer allows for an extension to the floor and headspace of a loft space. They usually extrude from the back of the house.

There are a three main types of dormers Flat roof dormers – these are the least attractive due to their flat appearance. Gable fronted dormers – these have two sloped sides and are more aesthetically pleasing. Hipped roof dormers.
Velux loft extensions are also very popular, as it is often the most straight forward roofing project if you already have ample space in your roof. These kind of extensions involve installing Velux windows into the existing slopes and does not require any planning permission either.
Where you have restricted space in your attic we can also advise you on the best loft extension London plan for raising your roof, such as a Mansard attic extension. This type of conversion has two slopes, and is named after a 17th-century French architect Francois Mansart (1598-1666) who first innovated this style of roof extension on his buildings. A mansard loft extension will require planning permission, and is the most expensive as it requires the most work. It is most compatible with older properties and you rarely see them in the suburbs. If you have a semi detached, detached or end of terrace property, a Hip to Gable loft extension may be the attic extension for you. This involves making big changes to the roof. Generally houses with hip roofs don’t have enough internal space for a extension to be practical, so a hip to gable conversion is the best solution.

Because a hip to gable extension does change the basic structure and shape of the roof it is likely to require planning permission. Once the roof has been extended the conversion is normally completed with either velux rooflights or a dormer.

What are the requirements for a standard London loft extension?

Before we proceed with a loft extension your attic space will need to be assessed properly so that we able to check the full extent of the work. Water tanks and chimney spaces may need to be worked around and re accommodated. There also needs to be a minimum head height of at least 2.2metres for a loft room. If the loft space is not big enough then the roof may need to be raised which will be more expensive. If you require greater floor space in the attic then we recommend the use of dormers.
In London housing stock you will generally find two main types of roof construction. Traditional framed roofs and Truss Roofs. Traditional framed roofs were prevalent pre 1960’s and have usually been constructed on site. These kinds of roofs are most suitable for loft extensions because the structure can be modified most easily.
After the 1960’s factory made truss roofs became popular as they were cheaper and quicker to install. They are not as strong as traditional framed roofs so more structural input is needed when it comes to converting a loft. It is more expensive due to greater skill needed to remodel the roof, but we have the expertise to deal with truss roofs. If you do have limited roof height there are two solutions you could go for.
Firstly you could raise the height of the roof by removing some or all of the existing roof and building upwards. This will require planning permission and exposing the roof, but we are able to work in all weathers. The second option is to lower the ceiling in the room underneath. This would be done in accord with building regulations and new joist would need to be installed.

Loft Staircases - what you need to know

The best place for a loft stairs is in line with the ridge of the roof, to make the best use of the height available. We require a minimum of 2m above the pitch line. Usually there will be between 13 and 16 steps with a step rise of 2.2m. The pitch angle should not be greater than 42degrees. Bringing light into your loft. Velux roofs and sky lights are of often the most cost effective and easiest way to give your loft light and ventilation. These are metal framed windows that are set into the slope of the roof. Dormers offer light at the end of the dormer construction All windows must be able to be opened for cleaning. The glass used will be heat reflective to avoid the conversion becoming too hot on a sunny day. If the roof is very high then you will need to be able to control the window opening an closing remotely Certain building regulations will require the window to be suitable for a fire escape

Fire Safety Regulations for your loft build

We will install fire resistant flooring as standard in all attic extensions. We will also install at least once mains operated smoke alarm in the loft in each circulation space.
