Waltham Forest

The London Borough of Waltham Forest is a London borough in north east London, England. The local authority is Waltham Forest London Borough Council. It covers a total area of roughly 14.99 square miles. The borough is positioned in between Epping Forest and Essex in the north, Redbridge in the east, Newham and Hackney in the south, and Haringey and Enfield to the west, where the River Lea and Lea Valley and the surrounding parkland forms a green corridor separating north and east London. Significant districts are Leyton and Leytonstone in the south, Walthamstow at the centre, and Chingford in the north.

As outlined by population estimates from the middle of 2014, Waltham Forest is a borough with a permanent population of about 268020 people. The north and south of the borough, split by the North Circular Road, contrast markedly in terms of ethnicity and socio-economic indicators, with built-up urban districts towards the south having inner-city characteristics, and more affluent residential development to the north with open spaces, parks, and playing fields.

Historically referred to as the seat of the Arts and Crafts Movement under the stewardship of William Morris, Waltham Forest continues to help lots of contemporary artists and art groups. The annual E17 Art Trail, which includes open studios, exhibitions and events, is the most significant art occasion in the borough, and there is certainly now a equivalent event in Leytonstone. Waltham Forest was on the list of six London boroughs that hosted the 2012 Summer Olympics.

• How to set the budget?

There are so many factors that can affect the cost of an extension, so it’s better to get the costs from your builder before proceeding.
