Property owners often choose a basement conversion due to the large amount of additional space they may gain or because they’ve already had a loft conversion and still need more space, but it’s not right for everyone.
If you’re planning a simple conversion with one of the basement companies in London, this will only take a month or so, but a larger project that extends under the whole house will take months, as it’ll be necessary to underpin the property. In some instances you might need to move out while the work takes place, but in the majority of cases you can stay living there.
An important area to bear in mind with a basement conversion is the height of the room. Taller ceilings will give you a better space, but this will involve a greater cost, as you’ll need to dig deeper. Building Regulations don’t specify a minimum height, but 2,400mm is seen as a practical level. You’ll need to account for the screed build-up, insulation and the flooring, and when you’re speaking to basement companies in London they’ll help you decide on the best height for you.
Terraced and semi-detached properties are best suited to basement extensions. The final costs will obviously depend on the level of fixtures and fittings that you choose and what you intend to use the space for. For example, a kitchen extension that requires water and gas supplies will cost more to fit out than a simple living space.
The problem of planning permission can put home owners off choosing a loft conversion, but the Rights of Permitted Development can mean that it’s not necessary. If you’re in doubt about what’s allowed, it’s advisable to speak to your local planning department.
The most common use for a loft conversion is as an additional bedroom or bathroom, and these can be achieved relatively cheaply. Where plumbing work is required, you should discuss the design with your builder to make it as easy as possible to install.
Loft conversions can suffer from being dark spaces if there aren’t enough windows, but adding in some skylights will open up the space and provide additional ventilation. When you’re planning the design of your new loft, you should speak to your builder about the best locations for these in order to get the most benefit. If you wish to use dormer windows, you’ll need planning permission, as these come out from the original part of the roof.
Both loft and basement conversions that are well designed and constructed can add aesthetic and financial value to your property. They enable you to adapt your house to suit your requirements rather than having to move.
