Basement Conversion Costs
Material Costs, Labour Fees and Time Frame Estimates for Basement Conversion
One of the things that motivate people to get their basement converted is lack of space. In London and various other cities where house prices are sky-high, a basement conversion may be a good idea. Whilst the project is definitely not going to be cheap, it would be a much cheaper option compared to the costs involved when moving to a much larger property. Especially if you consider the removal costs, stamp duty, as well as the additional costs of getting a much larger property.
Basement conversions are also effective at maximizing your property’s potential, allowing you to create an additional leisure space. The space may be used for a variety of purposes such as a playroom, media room, gym, games room, granny or nanny flat, extra bedrooms, artist studio, extra bathroom, swimming pool or even a sauna.
There are endless possibilities and regardless of how you wish to utilise the additional space, you can expect that it will really increase your property’s value.
Basement conversion projects are always going to cost less especially if there’s no need for an excavation to be carried out, especially when it comes to underground spaces. The excavation is usually the costliest part of the job, especially if there are sewers and drains, concrete slabs, and other excavated materials that may be causing problems.
If excavation is no longer necessary, the job will just require getting the space waterproofed to make it habitable, light, and safe access. When converting space which doesn’t require any headroom will usually cost less.
When doing the project, most builders would need to use your front garden not only for access but also to create a means to exit or enter the new level externally. Getting the garden landscaped as part of the conversion effort may also be included in the quote you will get as well. But this may not always be the case with all contractors. It helps to include gardening work in your budget. Otherwise, you’re in for some serious gardening session.
Across Europe, the UK is known to build the smallest homes. This is usually due to the high costs involved when acquiring land with building permission. There is also a problem with lack of space. With basement conversions, you can add another story to new builds without the need to secure more land space. You can even choose to add several storeys if you wish to. The addition of a basement is a great solution for lack of space. Space is costly especially in London and other inner cities.
As a result, basements that are many storeys deep are excavated underneath existing properties. A cheaper option would be to build a floor underground while the house is still being constructed. The retrospective addition of a basement will be generally more expensive. Still, if you’re in need some extra space then this is the best possible choice for you.
If you’re looking for the cheapest option, a simple basement without any windows and other fancy features would be a worthy idea to pursue. This would work well as a wine cellar, utility room, workshop or general storage. If you’re willing to spend more money however, you can get the space upgraded and transform it into a games room, gym or sauna.
But if your goal is to utilise it as a living space, expect to spend more money as well as additional costs in order to meet specific building regulations.
When creating extra space for your home, always remember that light is a crucial component. See to it that the living space will get priority in terms of daylight. If there is space in the middle of your floor plan that doesn’t get light-wells, you can have it utilised as storage space, cloakroom, or utility room.
You can incorporate a number of light-wells to maximize light by using glass balustrades for your open plan stairwells, partition walls made of glass, doors that are glazed or partially glazed, well as open tread steps, a good lighting scheme, as well as roof-lights with the basement extending underneath the garden.
