Lewisham

The London Borough of Lewisham is a London borough in south-east London, England and forms a part of Inner London. The borough wascreated in 1965, by the London Government Act 1963, as an amalgamation of the former location of the Metropolitan Borough of Lewisham and also the Metropolitan Borough of Deptford, which had been created in 1900 as divisions of the County of London. Nonetheless, minor boundary adjustments have occurred since its creation. One of the most important amendments were made in 1996, when the former part of the Royal Docks in Deptford was transferred from the London Borough of Greenwich.

The local authority is Lewisham London Borough Council and it is based in Catford. The borough covers a total area of approximately 13.57 square miles. It is surrounded by the Royal Borough of Greenwich to the east, the London Borough of Bromley towards the south and the London Borough of Southwark towards the west. The River Thames forms a short section of northern boundary with the Isle of Dogs inside the London Borough of Tower Hamlets. Deptford Creek, Pool River, River Quaggy and River Ravensbourne pass through the borough.

Based on population estimates produced during 2014, Lewisham is a borough with about 291933 permanent residents. Around 43 per cent of households are owner-occupiers. The Prime Meridian passes through Lewisham. Blackheath, Goldsmiths, University of London and Millwall F.C. are positioned inside the borough.

FAQs

How long will my garage conversion take?

It’s often said that a garage conversion can take anywhere between 1 week to 1 month, depending on the size and scope. But many standard conversions without any plumbing can take as little as 5 days. Your contractor will be able to tell you exactly how long your garage conversion will take.

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 long does a garage conversion take?

Garage conversion is a great way to add extra usable space to your home without having to extend your property. A fun fact is that, in the UK if you have your car parked in the garage, you’re in the minority. According to a research carried out by Admiral Loans, just about 33 percent of home owners in the UK store their cars in the garage. For most people the garage is literally a dumping ground that’s never fully utilized as such. In recent times, the garage is now being used to store a variety of other stuffs asides a car which includes garden furniture, tools and appliances, utilities such as washing machine, fridge and freezer as well as food and groceries. These facts show that more and more people are underutilizing their garage when they may actually be in need of more usable space in their property. So why not put into consideration converting the garage into a new space that would be able to serve more purpose?

If you’ve decided to convert your garage, you’d probably want to know the how long the project will take. There are a wide range of factors that can determine the duration of a garage conversion project. These factors include:

• If the foundation needs reinforcing

• If the floors, walls, or roofs are in a bad condition.

• If the ceiling height needs some raising

• If the insulation required in newer builds.

All aforementioned factors will make the garage conversion project take longer than expected. However, in normal situations garage conversions are relatively quick to complete once you start the building works. A single-car conversion will usually take about 3 to 4 weeks to complete depending on the existing garage’s structure.

Will I need planning permission or building regulations approval?

You may need planning permission if you are planning a larger extension. All extensions will need building regulations approval. An architect can assist with this and if planning permission is required. A reputable contractor will also be able to advise you if this is needed as well.
