Merton

The London Borough of Merton is a borough in south-west London, England. The borough was formed under the London Government Act 1963 in 1965 by the merger of the Municipal Borough of Mitcham, the Municipal Borough of Wimbledon plus the Merton and Morden Urban District, all formerly inside Surrey. The borough derives its name from the historic parish of Merton, which was centred around the location now generally known as South Wimbledon. The local authority is Merton London Borough Council.

Merton covers a total area of around 14.52 square miles. Merton is served by a wide range of National Rail stations across the borough, as well as the southern tip of the London Underground's Northern line along with the District line on the Wimbledon branch. It's the only London Borough which has tube, rail and tram services.

The main commercial centres in Merton are Mitcham, Morden and Wimbledon, of which Wimbledon is the largest. Other smaller sized centres consist of Raynes Park, Colliers Wood, South Wimbledon, Wimbledon Park and Pollards Hill. Every year, Wimbledon, one of the 4 tennis Grand Slam tournaments, takes place at the All England Lawn Tennis and Croquet Club in Church Road Wimbledon. The occasion occurs over a fortnight at the end of June and beginning of July and it's the biggest annual sporting event to take place in the UK, attracting more than 200000 guests during the Wimbledon fortnight.

FAQs

what is a garage conversion?

What is your garage being used for? If your answer is anything besides your vehicle, you’re in the majority in the UK. In the country, according to a research by Admiralty Loans, several home and property owners now use their garage as dumping ground for all sorts of stuffs asides a car. Ultimately, this gives rise to garage conversions as the more or less underutilized space can be converted into a living space which can be more beneficial while also adding more value to the property.

A garage conversion is a fast and relatively affordable route to adding more floor space within your home. It’s basically the act of changing your garage into something other than a storage or a place in which you can park your car. This can be anything from a bedroom to a playroom and anything in between. It’s a great way to provide extra space to allow your family to spread out and have more privacy while still within the walls of your home.

A garage conversion project is a huge one which mostly does not require a planning application so far the conversion is internal. However if you’re planning to increase the garage’s size or change the exterior of your home, or convert your garage into a separate room, then you may require a planning permission before getting started. It’s always wise to consult your local authority before carrying out any work to be on the safer side.

A project of garage conversion’s magnitude is better left to a reliable professional who have the experience when it comes to dealing with building regulations and more. This way, you’d also get to save yourself some headaches and some extra cash which may result from possible costly errors.

how much is a single garage conversion?

Converting your garage into a habitable room can be an option that’s too good to pass up especially when you’re in dire need of more living space in your home. If you’re in a similar situation and considering the cost of a single garage conversion in your home, then you’ve come to the right place! The fact is, the cost of a single garage conversion is dependent on a number of influencing factors which includes your specific plans as well as your location. Generally, the price of garage remodel is expected to cost about half of what you’ll incur when building a home extension or addition from scratch. However, before commencing a project of this magnitude you should put into consideration some things.

A single garage conversion is a huge job which typically involves wall insulation, floor raising, heating addition, cool and ventilation as well as updating doors and windows. Before you get started you should consider if converting your single garage into a room is a good option, whether a permit is required to convert a garage, the type of room a garage can become, does it add value to your home and how much its going to cost.

Just like any other home improvement project, garage conversion cost varies depending on several factors like your garage space specifications. Other factors include the general condition of your garage - the condition of your foundation, walls, floors or roofs, the ceiling and more, planning applications, your location, the services of a structural engineer, internal or external garages etc. According to Santander, the average cost of converting a single garage costs approximately £6,300. However, considering the aforementioned influencing factors we’d expect the cost of a single garage conversion to cost within the range of £5,500 to £10,500.

how much does a garage conversion cost?

Are you looking to create some more space in your home with your garage being almost dispensable? If yes, then considering a garage conversion project may be the way to go. Unlike many other extension options, garage conversion does not take up an additional space as it only changes the current structure of the garage. As a result, the cost of completing a garage conversion project can be relatively attractive when compared to other space creating alternatives. So exactly how much would a garage conversion project cost? Well, there’s no precise answer for this as several influencing factors come to play. However, in this guide we’ll give you a rough idea of the average costs that you’re likely going to encounter. Some of the factors that can influence your budget dramatically includes the following:

• The size of the conversion. The larger the size of the garage per square feet, the more cost you’ll have to expend.

• The type of your property - listed buildings are usually more expensive.

• Your location in the UK. If you stay in London where there’s a higher demand, you’ll most likely pay more.

• You’re likely to pay more if a specialist knowledge is required.

• The amount of glazing to be installed

• Quality of the materials to be incorporated.

• Quality of the professional to carry out the installation service.

On average, when it comes to garage conversion projects, you’re likely to pay the following depending on the per square metre given:

• A single garage of about 15 square metre will cost within the range of £6,000 to £15,000.

• A double garage of about 30 square metre will cost within the range of £12,000 to £30,000.

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.
