There are minimum practical requirements for headroom which the designs for your loft conversion must be able to meet.
Minimum legal height attic conversion.
Otherwise there is little point in converting the space at all.
Windows and openable area.
More than 50 of the ceiling space should be on average a minimum height.
Providing that this requirement is met most properties will likely possess the potential to have the loft space converted.
Take a tape measure and run it from the floor to the ceiling at the tallest part of the room.
Minimum glazed area is required to equal or exceed 8 of the usable.
One way is by working within the home s existing footprint and converting the attic into living space.
The minimum height you need for a loft conversion is 2 2m and you can easily measure this yourself.
In a stairway 2 0m measured vertically above the nosing line.
But building regulations use this figure as a recommendation when the room will be habitable.
A ceiling height of 1 9 2 0 m once the conversion is complete.
The ideal scenario is if you can stand upright in the centre of your loft and raise your arm above your head without crunching your hand on the inside of the roof.
Victorian houses tend to be lower than those built from 1930 onwards so may not have.
It is about 2 1 metres 210 cm 7 feet 84 inches for a loft conversion if you can stand up in your loft you are doing well.
If it s 2 2m or more your loft should be tall enough to convert.
To pass code there must be at least 70 square feet where the ceiling height is 5 feet or higher.
Due to the slope of the roof and the required access headroom the feasibility of a loft conversion is dependent upon a minimum height of approximately 2 2 m 7 ft 6 in measured from the joist to the apex.
You need to have enough room to stand up and move around.
The minimum head height for a loft conversion is around 2 3 to 2 4 metres.
Where a property already has a steep pitched roof the eventual loft conversion will be much easier and ideally you are looking for headroom in the loft of around 2 2 to 2 6 meters.
Of course it is entirely up to you.
In an attic room with a sloping ceiling or projection below ceiling line or non habitable room or similar a height that does not unduly interfere with the proper functioning of the room or space.
