FAQs

How long will a loft conversion take?

It depends on the style and size of the conversion, but in general, a loft conversion will take between 1-2 months. A loft conversion is a substantial building project, and plans will need to be drawn up. This may add to the time it takes to complete your loft conversion.

an every house have a loft conversion?

If you’re having issues with the amount of space in your home and need an extra space without affecting your garden, loft conversion comes to mind. Not only is it a great solution to creating more living space within a home, but it’s also one of the most budget-friendly solutions you can count on to expand your space by thinking upwards rather than sideways. So if you’re thinking about converting your loft, one thing that almost immediately comes to mind is whether or not your house is suitable for loft conversion.

To answer the question of whether every house can have a loft conversion is a very simple one. Generally, not every house is suitable for loft conversion. This is due to the fact that each and every loft space - from the stairways below and floors to the rafters and the roof up above, is unique. Therefore, the best way to really figure out whether or not a house’s loft offers the potential for conversion is to get in touch with a loft specialist.

So what can make a house not suitable for a loft conversion? Let’s take a closer look!

✓ A house will not be suitable for a loft conversion if the height of the ceiling happens to be too low and it’ll not be possible to have it raised.

✓ If you do not own own the freehold to the loft space, you won’t be able to convert the loft. Surprisingly, this happens to be a common issue in London.

✓ You will not be able to convert your loft if you reside in a conservation area or in a listed building. But you can identify a design solution that’ll still comply with the conservation rules and keep planners happy.

how long does a loft conversion take?

If you’re about to carry out a loft conversion project, you’d probably be wondering how long it’ll take to complete the task. Well, you’re not alone! This is one of the most common questions when it comes to loft conversion projects, however, providing a set timeframe for completion of such projects is impossible as all loft conversions vary. There are different factors that can determine the duration of your project. These factors include, the materials to be used, the type of the proposed loft conversion, the kind of staircase you’ll like to have installed, the number of windows included, the number of rooms to be added as well as a number of other influencing factors. As a result of these variables, the milestones and timings provided are only to be taken as guidelines. If you’d really like to have a set date, you can get in touch with a professional for help.

Generally, it’ll take up to 8 weeks to complete a loft conversion project.

✓ The first week activities will include putting up scaffolding, receiving the first materials for the build and creating an opening in the roof to gain access to the loft space.

✓ In the second week, the structure of the roof will be ammended and more support added.

✓ Third week, the floor joists will be fitted, building of the loft conversion will start, completion of the external roof works and commencement of plumbing and electric works.

✓ Fourth week, complete the building, construct the loft floor, fit the roof windows, insulation, ventilation and internal stud walls.

✓ Fifth week, apply plaster and plasterboard to the room walls, create a staircase opening and fit the new staircase.

✓ Sixth week, plaster the staircase area, complete plumbing and electrical works, hang the doors, fit skirting, handrails and bannisters and start decoration.

✓ Seventh week, complete the decoration and clean and wipe out all wastes.

✓ Eight week, complete all the remaining tasks.

Will I need planning permission to convert my loft?

Planning permission is not normally needed for a loft conversion as they are covered by permitted development rights. A conversion company will tell you if you do and help you with this. For more information, see our article about planning permission.
