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.

Are you considering converting your garage into a more usable space in your home? If yes, then you’d probably want to know if you’ll require building regs before converting the garage. The answer to this question is yes. Although you may not require planning approval to convert your garage into a more usable space, but you’d usually need approval under the Building Regulations.
When re-structuring your garage into a habitable space, the following should be taken into consideration: structural alterations, ventilation, moisture proofing, insulation, fireproofing, escape routes as well as the submission of a building building notice or full plan application to the local council in order to inform them about the planned project.
• Walls
You’ll require an approval if you plan to infill the garage door with a window and a new wall. This is because the garage may have been built of a shallow slab which implies that a new foundation would be needed for the new wall construction.
• Floor
Even though there’s a high possibility that the garage floor is strong enough for domestic use since its designed to withstand the weight of vehicles, you may however need to upgrade to make sure it suitable for both thermal insulation and damp proofing. In addition, there may also be the need to to alter the floor level in such a way that it matches that of the remaining parts of the house.
• Ventilation
According to the Building Regulations requirements, there’s a need for adequate ventilation for each individual rooms which includes garage conversions for general health purposes. What’s going to determine the ventilation level that’ll be required is the frequency at which the room is used. Ventilation can be provided through purge or simply opening the window or via trickle ventilation.
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.
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.
