Architects Design


Once our company has been appointed, we will then complete a full measured property survey as well as discuss your intended basment usage so the architect can draw up a proposed layout. This will then get adjusted until you feel you are 100% comfortable with the results. With extensive background in basement design and construction in London, both residential and commercial, the architect and design team will make sure that the proposed design and layout will optimise space usage in the same time obtaining as much incoming natural light as possible, which is paramount in a basement construction. At this stage, the architect will also advise the requirements imposed by your local council and if any investigative works need to be completed before planning submission. This can vary from tree reports, soil investigation to independent basement impact assessments. 

Structural Design


In most basement excavation projects, this will involve significant structural works requiring the implication of a qualified and experienced structural engineer. Our engineer will work closely with the architect  and complete his structural design and calculations. He will also aim to specify the most efficient means of not only providing structural stabilty to the newly built structure, but also ensure that this is economically designed which will reflect in the total cost of the works. 


If you opt for a basement design and build service with our company, Kapital Basments will take full responsability for the architects and structural engineers design. All our professionals carry a Professional Indemnity insurance as required by law and for your peace of mind.



Once all required drawings and surveys are completed, Kapital Basements can submit your proposed works for planning approval. 


Being one of Londons leading basement company, we have obtained vast experience with working with the local councils enabling us to identify the best approach for obtaining the Local Authoritys approval.  


Over time we have found that some of our clients have contacted us who already employed professionals like Architect and Structural Engineer and also obtained planning permission. We are happy to work alongside your chosen professionals to complete your basement conversion.

 Party Wall


A typical basement excavation or conversion project for a property that shares at least one party wall with and Adjoining Owner will include works covered under the Party Wall Act sections 2 and 6, section 2 covering works directly to a party wall (in case of underpinning) and section 6 covering basement excavation works within 3 meters of a shared or neighbouring structure. 


This aspect of the preliminary works will be discsused with you and upon your preference you can appoint your own party wall surveyor or we can assist and serve the notices on your behalf and arrange any related matters in this regard.
