Greenwich

The Royal Borough of Greenwich is a London borough in south-east London, England. Taking its name from the historic town of Greenwich, the London Borough of Greenwich was formed in 1965 by the amalgamation of the former area of the Metropolitan Borough of Greenwich with a part of the Metropolitan Borough of Woolwich to the east. The local council is Greenwich London Borough Council which meets in Woolwich Town Hall. The council's offices are also based in Woolwich, the principle urban centre within the borough. It covers an overall area of 18.28 square miles.

Based on population estimates from the middle of 2014, the borough features a permanent population of about 268678 people. The Prime Meridian running through Greenwich plus the Greenwich Observatory is exactly where the designation Greenwich Mean Time, or GMT started, and on which all world times are based.

In 2012, Greenwich was listed as a top ten international destination by Frommer's, rendering it the only UK destination to be listed. It is also the home borough of professional football club Charlton Athletic. To mark the Diamond Jubilee of Elizabeth II, Greenwich became a Royal Borough on 3rd February 2012. This is partly a direct result of its historic links with the Royal Family, and to its UNESCO World Heritage Site status as home of the Prime Meridian.

FAQs

Will my garage conversion cause disruption to the rest of the house?

It shouldn’t do. Most companies will do all the interior work first, and the last job to do will be creating the opening from the house to the conversion. A reputable company will make sure they cause as little disruption as possible during this time.

how much value does a garage conversion add?

It’s a fact that a garage conversion can go a long way to add a resale value to a home or property. Therefore, in the event whereby your home already has parking facilities in place you can put into consideration converting your garage into a habitable space which will add to the sales price of the house by adding an extra room or increasing the floor space. So exactly how much does a garage conversion add to your home’s resale value?

Garage conversions can be seen as a cost effective means of adding more space to your house. However, not only does it add space, but can also add up to 20 percent to the value of your home. It’s also a way of adding an extra living space to your home that’s not under strict planning complication unlike the alternatives. Generally, if your garage happens to be connected to your house, the cost of converting it to another room should between £10,000 to £20,000. As a home owner, converting your garage into an extra room can help increase the value of your home by up to £45,000. And if you’re to comply with the set rules under permitted development rights, you may not even require to submit a planning application.

In the event whereby your garage is detached from your house or perhaps you live in a flat ( or maisonette) or a listed building , you’ll need to apply to the local authority before commencing your project. It’s always wise to check if there aren’t any planning conditions attached to your home or property.

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.

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.
