Basement conversions are common in London and if you are looking for information regarding getting a basement conversion in Marylebone, then you are in the right place. People are always looking for new places and sometimes the only reason to move from one location to the other is lack of space. This moving is quite expensive and there is a lot of research involved. Getting a basement conversion is one of the best alternatives to create that extra space you are looking for.

What is a Basement Conversion

Basement conversion as the word suggests refers to converting the basement into habitable space and you can convert this basement into anything that you want. You can have a home move setup, indoor library, a gaming area or just convert the basement to get an extra bedroom.

Almost all houses have a basement and this basement is used for storing unused items or the basement has all the tools and equipment that we don't use on a daily basis. This is not the most resourceful way of using the space because you could build something entirely different and customize it to make it your personal space that helps you make memories.

How is a Basement Conversion Undertaken in Marylebone?

There are different types of a basement conversion. If you have an existing basement you can either make changes to the basement and just convert it into whatever you like. There is also an option to extend the walls of the basement and make changes to the ceiling and the roof to go along with the conversion plan.

There is also a third option where you can dig a hole into the ground, get a basement, and then convert it into something you desire. These three options have a planning part in common because you would have to plan the entire thing beforehand, make estimates, and only then begin with the conversion.

A basic basement conversion demands no professional supervision. You can purchase the required supplies and modify the basement but if you are going to make changes to the basement, you need to get help from a local builder or get help from a company that offers basement conversion services.

What are the Requirements for a Basement Conversion in Marylebone?

There are certain things that you should take care of before getting a basement conversion and they are -

  • Steady Walls -

Having steady walls is important because the walls are responsible for bearing the weight of the whole house and while making changes to the walls even if the strength of a single wall is compromised the balance of the whole structure is compromised and there is a risk of the building collapsing.

  • Height of the ceiling -

Having enough headroom inside the basement is important. The basement is generally built to store products and if you want the basement to be habitable then you should consider extending the ceiling. Having a low ceiling can create a crooked feeling and you might have to bend your neck the whole time you are in the basement.

  • Ventilation, Insulation, and Wiring  -

The basement is below the house and there is no proper sunlight or ventilation inside the basement. There is always that musty smell in a basement and to get rid of this smell you should have proper ventilation. Insulating is also important to make sure that the room doesn't get too hot or too cold. Wiring can also be a common issue so make sure you have proper wiring and earthing inside the basement.

  • Plumbing -

Most basements have a washroom and it is important to connect the washroom flushes and other water outlets to the central drain system. Having clogged toilets is a common issue in converted basements.

Why are Permissions are Important?

Planning permissions are not important if you are not making any changes to the structure of the house. You need these permissions when you are making changes like extending the ceiling, walls, or making provisions for proper ventilation.

The local authorities will issue these permissions and we will go through the blueprints of the house and determine the house will complement a basement conversion. If the basement conversion poses a risk to the structural integrity, the permission for getting a conversion is declined.

It is illegal to get a basement conversion without getting proper planning permissions and if the local authorities find about this conversion, the owner will face a hefty fine, and the house might be seized too. There will also be problems while selling the house.

Costs involved with getting a Basement Conversion -

Getting a basement converted can be quite an expense but the costs depend on the size of the basement and the plans that you are implementing. The cost of converting an existing basement can be anywhere around £750 – £1,400 per square meter.

The cost change if you are trying to make changes to the walls and the floor and in this condition, the costs can go to £1,500 – £2,000 per square meter.

Digging a new basement space and converting it can cost anywhere from £2,000 – £3,000 per square meter

Conclusion -

A basement conversion is permanent and a big investment so it is advised that you take the help of planning companies and other agents for getting the basement conversion. We help you by giving you realistic ideas and can also help in implementing the idea as it is. We take care of everything right from the beginning to the end and charge an affordable fee which is worth the work and supervision that we undertake.
