Balham

Balham is a district in south London in the London Borough of Wandsworth. The settlement appears in the Domesday Book as Belgeham. Bal means ‘rounded enclosure’ and ham a homestead, village or river enclosure. The area has been settled since Saxon times, and Balham Hill and Balham High Road follow the line of the Roman road Stane Street to Chichester.

Balham encompasses the A24 north of Tooting Bec as well as the roads coming off it. The southern area of Balham which is close to Tooting Bec has a block of 1930s Art Deco flats referred to as Du Cane Court. There is also the Heaver Estate which is in Tooting, which comprises substantial houses. It was constructed inside the grounds of the old Bedford Hill House by local Victorian builder Alfred Heaver.

Balham lies among 4 south London commons, namely Clapham Common towards the north, Wandsworth Common to the west, Tooting Graveney Common to the south and the connecting Tooting Bec towards the east.

In the Second World War, on 14th October 1940, Balham tube station was badly damaged by air raids on London. People sheltered in the tube station during the raids, but a bomb fell in the High Road and through the top of the Underground station, bursting a water and gas mains and killing about 64 people today. Ian McEwan describes the event in the novel ‘Atonement’, published in 2001.

FAQs

Will the company deal with the building control application?

Most companies will make the building control application on your behalf and ensure that all the work is completed to the right standards. When a building inspector has inspected it, you’ll get a certificate. It usually takes around 6-8 weeks after completion to come.

what is a garage conversion?

What is your garage being used for? If your answer is anything besides your vehicle, you’re in the majority in the UK. In the country, according to a research by Admiralty Loans, several home and property owners now use their garage as dumping ground for all sorts of stuffs asides a car. Ultimately, this gives rise to garage conversions as the more or less underutilized space can be converted into a living space which can be more beneficial while also adding more value to the property.

A garage conversion is a fast and relatively affordable route to adding more floor space within your home. It’s basically the act of changing your garage into something other than a storage or a place in which you can park your car. This can be anything from a bedroom to a playroom and anything in between. It’s a great way to provide extra space to allow your family to spread out and have more privacy while still within the walls of your home.

A garage conversion project is a huge one which mostly does not require a planning application so far the conversion is internal. However if you’re planning to increase the garage’s size or change the exterior of your home, or convert your garage into a separate room, then you may require a planning permission before getting started. It’s always wise to consult your local authority before carrying out any work to be on the safer side.

A project of garage conversion’s magnitude is better left to a reliable professional who have the experience when it comes to dealing with building regulations and more. This way, you’d also get to save yourself some headaches and some extra cash which may result from possible costly errors.

do i need planning permission for a garage conversion?

Are you thinking about converting your garage into a new space? Be it a new bedroom, gym, library or playroom, one thing you’ll have to consider before getting started is whether or not you’re going to require a planning permission. Unlike extensions that needs additional space, garage conversion is all about changing the existing structure of a space that’s already available to you - your garage. As a result, these projects are mostly covered by a planning policy that’s a bit different.

For a garage conversion, it’s very unlikely that you’ll need a planning permission. As a matter of fact, only 10 percent of garage conversions has been estimated to need a full planning permission, with the others coming under the permitted development rights. The permitted development rights, however, only provides coverage for home improvements that’s internal which implies that so far you’re not trying to enlarge your garage, you’ll not require a planning permission. But if otherwise, you’ll have to submit an application before commencing your project.

If you’re looking to comply with the permitted development rights, then your project must comply with some specific guidelines. These rules include the following:

• The work should be internal. No plans to enlarge or extend the existing garage.

• You should make sure that the materials used in carrying out the garage conversion is the same with the materials used in building the existing house.

• The building should not be extended.

You may, however, require a planning permission if you’re going to change a detached garage into a living space which could be a bedroom, small annexe or a living room.

Some houses excluded from the permitted development rights include flats, listed buildings, some new developments and most homes in a conservation area.

how much does a garage conversion cost?

Are you looking to create some more space in your home with your garage being almost dispensable? If yes, then considering a garage conversion project may be the way to go. Unlike many other extension options, garage conversion does not take up an additional space as it only changes the current structure of the garage. As a result, the cost of completing a garage conversion project can be relatively attractive when compared to other space creating alternatives. So exactly how much would a garage conversion project cost? Well, there’s no precise answer for this as several influencing factors come to play. However, in this guide we’ll give you a rough idea of the average costs that you’re likely going to encounter. Some of the factors that can influence your budget dramatically includes the following:

• The size of the conversion. The larger the size of the garage per square feet, the more cost you’ll have to expend.

• The type of your property - listed buildings are usually more expensive.

• Your location in the UK. If you stay in London where there’s a higher demand, you’ll most likely pay more.

• You’re likely to pay more if a specialist knowledge is required.

• The amount of glazing to be installed

• Quality of the materials to be incorporated.

• Quality of the professional to carry out the installation service.

On average, when it comes to garage conversion projects, you’re likely to pay the following depending on the per square metre given:

• A single garage of about 15 square metre will cost within the range of £6,000 to £15,000.

• A double garage of about 30 square metre will cost within the range of £12,000 to £30,000.
