Basement conversion

When you pay a visit to your friends or relatives, you will often see some idle large spaces on the ground floor, between rooms, and along the stairs with no light connections and just full of used boxes and polythene papers. Hideaways are not even hygienic and often have some unwelcomed smell due to neglect by the homeowners. In some homes, they are used as through ways and nothing else. Yet it is a big space that can harbour a three-bedroom house.

There are some instances when you need more rooms for your house because you feel like the living room is small, the capacity of your family have also increased, and the area you are living in has a limited space which restricts you from even building a kennel for your lovely puppy, leave alone putting up a new house. Converting this idle space to a more reasonable extra room for you to use is the meaning of our title-basement conversion.

In this post, we are going to take you through some guide on how you can do a basement conversion for your house, the building regulations and how long it can take to finish the work.

Basement Conversion London

How to convert a basement:

There are several ways through which this can be done, but in this article, we are just going to take you through top three tips:

1. Building a new basement to an existing house without one

Doing a new basement to become part of an already existing mansion involves a lot of structural changes and is the most expensive of all the three mentioned here. It is like building a new house from its foundation. Even though this is the best way of converting basement, it might affect the overall stability of a house and can cause some damages such as breaking of window glasses, cracking of walls due to activities such as digging the ground, and other drills. In suburb dwellings where there could be no space for adjustment, building a new one is the most appropriate way to have a new room in the basement.

2. Renovating or converting an already existing cellar or basement to a more useful living room

This is the most preferred method of making those idle spaces into a living room. It is cost effective since you just need to design your already idle room to make it be inhabitable. The work of renovation doesn't involve a lot of fuss like when you are creating a basement for the first time. You only need to design windows, doors and ensure there is enough light supplied into the rooms, good painting, and your house is ready. This method cost very little depending on how you want the structure to be.

3.Doing an extension at the back towards your garden or at the front towards the entrance

In case you are privileged to have a garden or an extra space at the front, and then you can use it to add some adjustments to create a new extra room. Since it gives space for the workers, and it is a completely new area, the extension can have more stability than when it is built under an already existing house.

Cost of basement conversion:

The cost of conversion depends on the location of the home and the method used for conversion. Building a new one is actually the most expensive one as it entails a lot and the cheapest is doing a renovation to an already existing one.

Duration of basement conversion:

The question of how long does it takes to finish the work is based on a number of factors and the availability of funds to finance the work.

But in regard to the methods mentioned, building a new basement from an existing house takes much longer because it involves a lot of work and strategies to ensure that it doesn’t interfere with the whole building.


This is the best way to get new extra rooms for your house without acquiring new land. Please don’t just start the work before doing a feasibility study and seek permission from the Building Regulations Authority within your area.
