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 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.

do you need an architect for a garage conversion?
Have you decided to convert that under-utilized space ( garage) in your home to a more habitable space where you can do anything asides general storage or parking a car? If yes, then you’d probably want to know where to start or if you’d require an architect to get started. Well, you’re not alone! This is one of the most frequently asked questions when it comes to garage conversions and reasonably so. Talking about where to get started, when it comes to home improvement projects the first step to take is determining whether or not you’d require a planning permission or if your proposed garage conversion is covered under permitted development rights. Once you’ve been able to conclude on that, the next step is deciding whether you’re going to complete the project yourself, hire the services of tradesmen or employing a builder. And this ultimately brings us to the question of whether you’ll need an architect for a garage conversion. To get started, it’s highly recommended that you employ the services of a professional architect or an architectural technologist to assist in designing your garage conversion. However, most garage conversion projects are straightforward with no complex changes to be made so far you wish to avoid applying for a planning permission and staying within the set guidelines of the permitted development rights. In such events, if you’re properly trained and well experienced in the field, then it may be cost effective to design your garage conversion by yourself. It should, however, be noted that it all depends on your personal preferences and budget. If you’re on tight budget and don’t mind a straightforward design, you can save cost by not hiring an architect.
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.

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.
