If you are considering a large or a small-scale project We can help you with all your construction needs.

We have noted during the course of our works that there are jobs that if designed differently we could have saved the client substantial sums of money.This indeed was the case before we started our works to develop the site Surbiton, Thames Ditton, Surrey. The design as it was drawn was complex and in partnership with the client and the main contracting team, we managed to make large cost savings resulting in the development becoming cost effective. Please see our case study (Portsmouth Road).

We have an in house team of:

Architectural Designers

Structural Engineers

Quantity Surveyors

Main Contracting Team

Geotechnical Soil Engineers

I want to develop What do I do?

If you have planning permission, then you have overcome the first hurdle.
If you have not, then no worries we can help you in the following way –
Our expert planning advisers will meet with you and discuss your project in detail. They will take into account and tell you what is possible and doable in a no-nonsense way.
Our initial advice and guidance are free of charge and during this process we will also give you an outline cost guidance as to how much your project will cost to complete including all the professional fees, utilities, legal and construction costs.
During the initial stages we will advise you of the timescales involved and the pitfalls one will face during the planning process. Our approach is one is to help you manage your risks and ensure that you do not get caught in a quagmire of planning nightmare.
Prior to going to planning we will also look at the geology of the site, which may mean doing some limited geotechnical soil testing to ensure that the ground will not present us with surprises, and this will basically help us define the cost of the development.
We have come across some projects where they could not proceed since the cost of building become formidable due to the poor ground conditions. If this was known well in advance this could have saved the client a fortune and a lot of disappointment!
Once planning has been obtained, we will proceed further with you confirming and agreeing with you the true cost of the development. At this stage we should not have any surprises since the planning process would have involved a design that makes the project cost effective and fits within your budget.
Throughout the process we will work with you for example on about the internal finishing’s such as interior design and the landscaping of the property.
If you wish we can also provide a design and build service on the structural element only. This basically means for example we can construct the basement, install the drainage, foundations, the steel frame, concrete frame of the building including the floors and the roof. Leaving you to complete the rest of the building fit out.

The following are members of our design and build team

Construction of new basement externally within reinforced waterproof concrete walls and reinforced concrete slab. The internal basement was constructed by extending the existing foundations using an underpinning method and the these walls were then lined with a 150mm concrete wall. The ground was battered back and the excavation done in a piecemeal way. We installed the drainage and sump pumps installed for waterproofing. Waterproof concrete was used as the first line of defence and the internal walls were finished with a delta membrane.

TESTIMONIALS

WHAT OUR CLIENTS SAY

"We hired CSMANLTD to design and build a basement under our family home, and the entire process was seamless. Their team took care of everything—from underpinning and excavation to drainage and structural integrity—offering expert advice at every stage. The project was completed on time and within budget. We now have a stunning living space that has transformed our home. Highly recommend their design and build service!"

Anil Barua

construction worker

"CSMANLTD has become our go-to partner for pre-construction groundwork and basement development. Their in-house engineering team provides invaluable insight during the early stages, allowing us to begin on-site work while final designs are being approved. Their ability to handle piling, deep excavations, and below-ground utilities has saved us significant time and cost across multiple projects. A truly unique and reliable approach to construction."

Haris Mila

construction worker

"We collaborated with CSMANLTD on a mixed-use development requiring complex temporary works and deep foundation solutions. Their expertise in structural engineering and piling was evident from day one. They delivered a robust, cost-effective design-build solution that kept the project on track. Safety was a top priority on site, and their team operated with professionalism throughout. A standout contractor in the industry."

Andreas Akkidis

construction worker

"As architects, we value contractors who understand both design intent and structural feasibility. CSMANLTD bridges that gap perfectly. Their in-house engineers work closely with our team to optimise structural frames, foundations, and basement construction—often suggesting innovative, cost-saving alternatives without compromising safety. They are a true extension of our professional team."

Solomon Solon

construction worker

"Our Victorian house had foundation issues and limited space. CSMANLTD assessed the structure, recommended underpinning, and constructed a full basement beneath our garden—maximising space without affecting the main house. The work was clean, safe, and incredibly well-managed. Now we have a gym, cinema room, and extra bedroom. We couldn’t be happier with the result."
