Frequently Asked Questions (FAQ).
HOW MUCH WILL A BASEMENT CONVERSION BE?
It is not straight forward because each individual project will be different and will depend on a number of aspects. We need to closely look into multiple factors such as the materials needed, the clients’ vision, the budget and the timeframe before we can give a clear quotation. With that being said, we can give a rough estimate during the site visit meeting. From our previous experience in basements, we can give some understanding of what you might expect:
BASEMENT CONVERSION COSTS:
£4700 – £6720 PER SQ M APPROX.
This figure is a rough idea at what a basement conversion in the Wandsworth area will cost. The range is a correlation between the different level in the finish. There is always the possibility of other costs being incurred when looking at in greater depth.
Considerations as to whether the initial dig out will be possible by machinery or it will be necessary to excavate by hand. This will ultimately be more expensive.
DAMP PROOFING AND DRAINAGE:
£1200 – £2400 PER SQ M APPROX.
We use Delta membranes for damp proofing. Depending on the state of the walls and the ground, Damp proofing membranes can be used to full or medium coverage.
Is planning permission obligatory?
For the most part, you will not need a planning permission for a basement excavation, as the changes do not breach the area of your building plan and usually wont exceed outside your building structure. However, there are times when parts of the basement conversion project may require planning permission if it does goes outside of the building plan. Your local council is the first contact point when it comes to the planning permission.
It is always recommended that you should be familiar with basement conversion requirements before you start planning your project.
Do I gain financial benefits from a conversion?
Not only does adding additional space improve the scale of a living space and boosts comfort, market research shows that you will also gain financial benefit if you wish to sell your property in the future. Basements can be transformed to amazing living spaces such as wet rooms, spas, pools and entertainment rooms with proper ventilation and heating.

British Standard 8102:2009
British Standard 8102:2009 is the ‘Code of practice for protection of below ground structures against water from the ground’. In essence, it is the primary design guide for structural waterproofing in the UK, with the recent update being released in November 2009. If you are producing a waterproofing design, or you have advisors that are designing on your behalf, this document should cover every consideration possible. If you have further questions in regards to the BS8102, please feel free to contact us.
Tanking, or ‘Type A barrier protection’ (BS8102 definition), is a specific form of waterproofing, although it is a common term applied to all forms of waterproofing. In the true sense of the word, tanking means blocking water out of a structure by employing a barrier product which is installed internally, sandwiched within, or applied externally to a structure. Tanking is still widely employed in new construction, but has declined in popularity in recent years where retrofit protection is required for existing basements.
An intuitive construction process of all basement conversion projects is monitored and overseen by managing director, Andi Pepaj, and managed by our project managers on site.
APT Renovation has over 17 years experience in underpinning and basement excavation adhering to basement standards to a very high-level finish.

Health and Safety at every stage
Health and Safety is of the utmost importance on every site that we work on, as it not only concerns all of our staff members, but everyone else in the vicinity; including you, your neighbours and even passers-by. Due to the nature of our work, there is always the risk of injury or even death, as ladders, tools and various other materials can be hazardous. Basement conversions in particular are technically very challenging, and can pose a number of different risks, with a large proportion of these projects in London regularly failing safety checks. Unguarded excavations and unprotected floor openings represent serious dangers to all those concerned. That is why our staff are expertly trained and will always diligently adhere to all necessary Health and Safety procedures and issues.
Waterproofing is a very important aspect in a basement conversion, particularly as the UK experiences a very high level of rainfall each year. A lack of waterproofing will eventually result in damp on walls, which not only looks bad, poor odours can be detrimental to your hygiene as well, and can cause significant damage to the paint job, the plastering and the finish. Worse still, damp can also lead to breathing problems and other health issues, so it is something that should be eradicated immediately.
APT Renovation has had huge success over the years in waterproofing with Delta Membrane Systems and pumps. For basement waterproofing, the Delta sealed system ensures that all membranes are expertly sealed and secured, as well as any protrusions or crevices. Delta Systems are incredibly effective in dealing with adverse water conditions and especially basements that have the propensity to flood. There is a 30-year guarantee on all Delta membrane systems
