What’s the best type of loft extension for London homes?
If you live in the capital, you’ll know that space is at a premium. That’s why a loft extension for your London home is a great idea.
This article will help you understand the different types of loft extension in London and identify which one is best for you.
It will also outline the steps to take towards creating the perfect loft conversion for your home.
Rooflight loft conversion
Rooflight extensions are the most affordable and versatile type of loft conversion. They involve adding rooflights (also known as Velux windows) as well as fixing a staircase and possibly reinforcing the floor.
This type of conversion is a good choice for any type of property, including terraces.
Dormer loft conversion
This type of conversion adds a box-like structure to your existing roof. You can choose a single, L-shaped or double-width dormer.
Dormer extensions are good for increasing both floor and roof space. They are especially suitable for terraced properties with an existing rear extension.
Hip-to-gable loft conversion
This type of loft extension transforms the sloping side of your roof into a vertical wall (the gable section), built to the same height as the ridge. A pitched roof is added to extend headroom and overall space.
Hip-to-gable loft conversions suit detached and end-of-terrace properties.
Mansard loft conversion
A mansard loft conversion adds an almost-vertical wall and a flat roof to your property, extending along its complete width. This structure helps to add extra height and living space.
It’s suitable for most properties, including terraces. Note that this is one of the more expensive loft conversion options.
Your loft conversion in London step-by-step
1. Assess your property
Your loft conversion plan for your London home starts by identifying whether your property is suitable. You will need to assess:
The head height, which should be a minimum of 2.2 metres.
The roof pitch, which should be above 30 degrees.
Any obstructions — for example, a water tank.
The roof structure. In pre-1960s houses, cut roofs allow plenty of space free for your loft conversion. More modern houses tend to have trussed roofs with W-shaped supports, these can also be converted.
You can consult with a builder at this stage to assess your property and discuss the types of loft conversion.
Alternatively, you ask an architect to plan and design your loft conversion. This route offers many advantages.
Firstly, an architect can help you design your loft conversion to suit your property and draw up loft plans for your London home.
An architect can also help with the paperwork involved in converting a loft and even project manage the whole build process if required.
2. Find out about planning permission
Most loft conversions do not require planning permission and can go ahead under permitted development (PD) rights. In this case, they must fulfil certain criteria.
Your architect will be able to advise you on these and other aspects of planning permission. If you need to apply for planning permission, they will be able to manage this process for you. If the loft complies with permitted development requirements, your London loft conversion architect will be able to apply to the council for a Certificate of Lawfulness, which verifies that your proposed loft conversion complies with permitted development, and does not require full planning permission.
3. Understand the Party Wall Act
If you live in a terraced or semi-detached property, you will need to be aware of the Party Wall Act. This is a set of guidelines to help you avoid or manage any issues with your neighbours if a building project affects a shared wall or boundary.
If you need a party wall agreement, you will need a party wall surveyor for this. Humphreys & Sons are a practice of both Architects, and Chartered Party Wall Surveyors, so unlike most architecture companies they can also help you with the party wall act process, all in house and under one roof.
4. Appoint your contractor
Get quotes from two or more builders before going ahead with your project.
If you’re working with an architect, they should be able to recommend contractors they have worked with before.
5. Project manage your loft conversion
Once work is underway, you will need to project manage your loft conversion to ensure that deadlines are met.
You will also need to keep on top of any paperwork, such as ensuring the work complies with building regulations. Again, if you’re using an architect, this is something they can advise on.
6. Put the finishing touches to your loft conversion
Once the structure is in place, it’s time to put the finishing touches to your loft conversion, choosing furnishings and accessories to create a welcoming ambiance.
