What are the dimensions of your property, and what is the height of the loft space?
These are probably the most important questions for generating an accurate price estimation, and will most likely require you to grab a tape-measure. Take a measurement on the first floor from the front of your house to the back and from one side to the other. You should record this in metres. If you have a rear addition or outrigger, measure it separately.
Next, you need to go up into your loft and find out how much height you have. Take a measurement from the bottom of the ridge timber to the ceiling joist (from the highest point of your loft to the floor).
Is your property on a red route?
Red routes are major roads that only make up around 5% of the capital’s roads, but carry up to 30% of its traffic. Check the red route maps to see if this applies to where you live.
Is your property a nationally or locally listed building?
Whilst local listing provides no additional planning controls, your local authority may choose to deny planning permission for projects that would normally be granted. Locally listed buildings may be altered under permitted development unless an article 4 direction is issued by the local planning authority.
Is your property within a conservation area?
Conservation areas exist in many parts of London, and are introduced to preserve the historic character of a particular location. Conservation areas use article 4 rules to prevent work being carried out under permitted development.
This means all proposed works to a property within a conservation area must receive planning permission, which often greatly reduces the scope for external changes. However, loft conversions are sometimes still possible within conservation areas. Check your local authority website to find out if your property is within a conservation area.
Is your roof hipped or gabled?
You probably don’t spend a vast amount of time in your loft or looking at your roof so you might not know this off the top of your head. If not, pop outside and take a look. For an explanation of hipped and gabled roofs, click here.
What material covers your roof?
If you can’t remember, check what sort of material you have on your roof, whether it’s slate, red tiles, or something more modern.
