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.

Can my loft be converted?

Many types of loft are suitable for a loft conversion. In general, you will need at least 2.3 metres of headroom in your existing loft. This is to make sure there is enough headroom after the conversion. Speak to a conversion specialist about the probability and possibility of doing this in your house.

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.

do you need planning permission for a loft conversion?

Typically, loft conversions do not require planning permission except in certain situations. They’re usually covered under what’s known as Permitted Development. Certain building works like loft conversion, rear extension and conservatories are granted planning permission by local authorities. Permitted Development, however, gives you a free range to improve your home without having any issues from the councils or regulations. Before your planned loft conversion can be covered under Permitted Development, there are some certain criteria that must be met. This criteria includes the following:

✓ The extension must not go beyond the existing slope of the roof at the front of the house.

✓ The loft space converted must not go beyond 40 cubic metres in a terraced house.

✓ The roof’s height must not be increased by the extension.

✓ The loft space converted must not reach beyond 50 cubic metres in a detached or semi detached house.

✓ The plan for the extension mustn’t involve structures like balconies, verandas or anything other structures of this nature.

✓ The roof extension should be positioned as far back as possible or at least 20cm from the existing eaves.

✓ The side that faces the window openings should be at least 1.7m beyond the floor and the windows should also be obscured.

✓ The roof extension must not overhang the existing roof or wall of the house.

✓ The materials that are to be used must be similar or the same to the materials that has already been used on the house’s exterior.

However, you should bear in mind that there are some properties that are exempt from Permitted Development. Examples of these type of properties include conservation areas, Areas Of Outstanding Natural Beauty and World Heritage sites. Permitted Development does not also provide coverage for listed buildings.
