Daventry

Daventry is a market town in Northamptonshire. It is 76.4 miles north-northwest of London and 13.9 miles west of Rugby. Sitting between 135 and 160 metres above sea level, it is encompassed by hills reaching heights of 225 metres. Daventry is situated on the watershed of the River Leam, which travels to the west of England, and the River Nene, which travels east. Nevertheless, there is not a river in the town and the most notable bodies of water come from two tanks that supply the canal that swings from Watford Gap into the West Midlands through a 1.9 kilometre long Braunston Tunnel. Daventry is traditionally a rural town with a modest population, having around 4000 residents in 1950. Expansion came about from 1955 when British Timken, the tapered roller bearing company, developed a large factory in the town. Combined with being assigned as an 'overspill' to settle people and industry from Birmingham in 1966 as part of an understanding with Birmingham City Council, the town proceeded to grow. There are a number housing estates, including Drayton, Middlemore Farm, Long Farm, Ashby Fields, Royal Oak, Timken, Stefen Hill, The Grange, The Southbrook and the Headlands. Regardless of such expansion, it did not reach the target population of 36000 by 1981, and the population of the town was documented as 25026 in the 2011 Census. The modern-day property and commercial project surrounds the town's celebrated market centre. 74 landmarks and buildings in Daventry's town centre are on the List of Buildings of Special Architectural or Historic Interest led by the Church of Holy Cross at Grade I, and structures such as Market Place and the Danetre Hospital Offices are Grade II listed. For all of your home upgrades, ensure to make usage of reputable contractors in Daventry to make specific of quality.

FAQs

when do you need planning permission for a house extension?

If you’re planning on adding a house extension to your property, you’d probably be worried about whether or not your proposed extension would require a planing permission. Well, it may be relieving to know that not every house extension project would require a formal consent, and in fact, several extensions are covered by the permitted development rights. Not only can this save you a considerable amount of time especially at the project’s planning phase, but it’ll also save you money on the application fee. In the UK, single storey extensions to the house’s rear can be 3 metres deep for both semi detached houses and terraces or 8 metres deep for detached homes.

So how do you know when you’d require a planning permission for your home extension? Well, if your extension plan fits these criteria explained below, then your project is most likely going to be allowable as a permitted development.

• For single storeys, the rear additions must not extend more than the original house’s rear by more than 3 metres in both semi attached homes and terraces (4 metres for detached houses).

• Extensions to the side must be a single storey with a height not exceeding 4 metres and not going beyond 50% of the original house’s width.

• Extensions hat within 2 metres of a boundary should have a eaves height not more than 3 metres.

• Multi storey addition must not extend beyond the original house’s rear wall by a maximum of 3 metres or 7 metres of the boundary opposite the rear wall.

• Permitted development rights do not apply in listed buildings or designated areas.
