In a city, where it can be difficult to extend outwards or upwards, digging down can sometimes be the only option. Make no mistake, a basement conversion is a major undertaking; some families even decide to live elsewhere while the major works take place.

How long a basement conversion will take is dependent on many things, from the type of property to how big and deep you are willing or able to go. At Simply Basement, we like to tackle cellar conversions in a systematic way. We have a three stage process, with some rough time estimates of how long it may take to have a Simply Basement conversion:

Stage 1

The first stage is the planning, design and approval process. We estimate that this should take somewhere between 4 to 6 months, depending on the borough of London that the property is located in.

Gaining planning permission can be the most time-consuming aspect of this stage and it may take a while. We will always ensure that any basement we propose will be in line with the planning guidelines of whichever borough we need to work with.

Stage 2

Once the design has been finalised and planning permission has been approved, it’s time to start with the major building work. Stage 2 will see structural digging, underpinning and tanking (waterproofing) taking place. This will be the most disruptive stage of your basement conversion. We estimate that these essential works usually take between 3 to 5 months.

It is during this stage that some homeowners may decide to move out. Such extensive building work can be noisy, dust filled and messy. However, we always endeavour to be as considerate and leave as little mess as possible at the end of the working day.

Stage 3

By stage 3, the major building works will have been completed; it’s time for the fit out. Depending on the size and complexity of the basement, this stage should take around 2-4 months.

The fit out can be one of the most exciting moments of the build, as you see the process coming together and it starts to look more like the living space you envisioned.

As mentioned above, these time frames are only estimates and the timings might change due to size, complexity or any unforeseen circumstances.
