Are you considering a loft space conversion so that you can open up space in your home to avoid the need to relocate? Then use our no cost and easy service to compare quotations and find the top cost for the work you wish completed.

Loft conversions are proving to become increasingly popular in the UK. In most houses the loft accounts for unused space which could go to better use. Converting can change the room into a bedroom, bathroom, playroom or even ensuite bedroom.

The fact is there's lots of potential to converting your loft, such as the added value for your home which can be up to 20%. Loft space conversions are also recommended over a house extension since the infrastructure has already been in place. Furthermore, you won't be taking away any garden space.

If the loft conversion would benefit your house and you're seeking more room, check quotes from reliable companies within Croydon and get the best offer for the work you'd like completed.

Croydon

The London Borough of Croydon is a London borough in south London, England and is part of Outer London. It covers an area of 33.6 square miles and is the largest London borough by population, being the home of around 376040 people. It is the southernmost borough of London. At its centre is the historic town of Croydon from which the borough got its name. Croydon is described within the Domesday Book, and from a tiny market town has expanded into one of the most populous locations on the fringe of London. Croydon is the civic centre of the borough.

Formed in 1965 from the Coulsdon and Purley Urban District and the County Borough of Croydon, the local authority Croydon London Borough Council, is now part of the local government association for Greater London, London Councils. The financial strength of Croydon dates back mostly to Croydon Airport which was a significant element in the improvement of Croydon as a business centre. It was the very first London Borough to have Fairtrade status which is awarded on certain criteria.

Premier League football club Crystal Palace F.C. play at Selhurst Park in South Norwood, a stadium they've been based in since 1924. Other landmarks inside the borough consist of Shirley Windmill, among the few surviving large windmills in Greater London built in the 1850s, plus the BRIT School, a creative arts institute run by the BRIT Trust which has produced artists like Adele, Amy Winehouse and Leona Lewis.

FAQs

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.

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.

how much is a loft conversion?

With the ability to add approximately one third of your existing living space ( by converting your old, unused attic) to your home or property without having to let go of your garden, it’s quite easy to see the reason why loft conversion has rapidly grown to become one of the most popular home improvements in the UK. However some homeowners usually shy away from the idea simply by looking at the perceived high cost of carrying out such a project, despite several researches showing that loft conversions offers the best rate of return on initial investment when compared to the other home improvement projects. So exactly how much would it cost to carry out this project?

Just like several other home improvement projects, the cost of a loft conversion varies greatly depending on a wide range of influencing factors. These factors include the size of your home, how old your home is as well as the quality of the fixtures and fittings you want to install. For instance, a high end bathtub alone can cost you thousands of pounds, meanwhile you can also construct a full bathroom suite on just a couple of hundred pounds. However, to give you an idea of the minimum cost of a loft project we’ll look at the most popular types and the minimum cost of each.

✓ Internal Loft Conversion - The most affordable type of loft conversion tends to start from £25,000 and above.

✓ Dormer or L-Shaped Dormer Loft Conversion. These are the most popular types of loft conversion. Dormer price tends to start from £35,000, while the L-shaped dormer starts from £45,000.

✓ Mansard Loft Conversion - This involves replacing the entire side of a sloping roof with a vertical wall and flat roof. It requires a planning permission. The type of loft conversion usually starts from £45,000.

✓ Hip To Gable Loft Conversion - This usually starts from £50,000.

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.
