FAQs
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.
A dormer loft conversion is a type of loft conversion that’s built making use of a roof’s existing slope. In other words, it’s an existing roof’s extension which is constructed in such a way that allows for an additional floor as well as head room especially suitable for lofts lacking good amount of usable space. The dormer loft conversion is simply an addition to the existing roof looking much like a box-like build constructed onto a pitched roof as it creates walls that are vertical to the slope while also being 90 degrees to the floor.
This type of loft conversion is the most common amongst homeowners in the UK mainly because it represents a cost effective means through which you can add an additional usable space to your home or property. The structure extends for the slope of the existing roof and can easily be altered to suit various tastes or styles. Furthermore, if you’re looking for a type of loft conversion that aids to foster reduced disruption to work, then dormer loft conversion is also your best bet. This is due to the fact that the structure is built from a scaffolding made outside a home.
There are different types of dormer loft conversion and the one which will best suit your property will depend on the property type, be it detached, semi detached or terraced as well as the existing roof shape and size. The dormer loft conversion is a popular choice for a lot of homeowners for a variety of reasons. Let’s have a look!
✓ It’s very cost effective
✓ The dormer loft conversion does not require planning permission so far it complies with certain conditions and limitations
✓ It adds an extra headspace as well as floor space.
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.
