Balham

Balham is a district in south London within the London Borough of Wandsworth. The settlement features within the Domesday Book as Belgeham. Bal signifies ‘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 and also the roads coming off it. The southern area of Balham which is near Tooting Bec has a block of 1930s Art Deco flats named Du Cane Court. There is also the Heaver Estate which can be found in Tooting, which comprises substantial houses. It was constructed in the grounds of the old Bedford Hill House by nearby Victorian builder Alfred Heaver.

Balham is located between 4 south London commons, namely Clapham Common towards the north, Wandsworth Common to the west, Tooting Graveney Common towards the south along with the connecting Tooting Bec towards the east.

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

FAQs

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.

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.

What kinds of loft conversion are there?

There’s a huge range of different types of loft conversions. The most common are dormer and skylight or Velux conversions. There are also hip to gable and mansard conversions. The type of loft conversion that’s most suitable for your property will depend on the style of roof and the size of your loft.

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.
