I worked with RDK Civil Engineering for both architectural and structural design for my home extension project, and I am extremely satisfied with their services. The team was professional, responsive, and detail-oriented throughout the process. Our architect, Sasith, was very helpful in guiding us through planning approvals and design changes, always providing clear explanations and suggestions. Diven, our structural engineer, ensured that all structural requirements were addressed accurately, and the calculations and drawings were precise and thorough. I also want to highlight Naveen, who was always ready to make amendments to the drawings whenever we had changes and kept us updated about the progress of the architectural process. His support made the whole experience smooth and stress-free. What I appreciated most was their collaborative approach and willingness to accommodate changes while keeping the project on track. Their expertise gave me confidence in both the design and structural integrity of my extension. I highly recommend RDK Civil Engineering for anyone looking for reliable and professional architectural and structural services.

RDK team were very nice to work with and helped us obtain the planning permission needed for our rear extension.

Great Experience from start to finish

Very professional and helpful. Highly recommended. We used RDK for our structural drawings for the rear extension. They were very prompt and helpful and got the design draft test in a week. Even after sharing the final design they have been helping out with queries from building control and our builder for a smooth execution. Real value for money.

Excellent service by Sasith! The local authority delayed my decision by over a month but the team were constantly requesting updates. Thank you RDK

They made a lot of effort to get my approval done. The council was making errors and rejecting the work but they did not give up until it was approved. Very helpful and accommodating staff.

I had an excellent customer service experience and RDK happy to make changes on the plan several times and answered all my queries and what a success story because planning was approved Bt BCC within less that 8 weeks. I will strongly recommend this company as they were also cost effective.

RDK Civil Engineering Limited were recommended to me by a builder I spoke to about building an annex for my family. Since first contact, everything has been pleasant, prompt and productive. There were a few issues with the council approving application and boxes they wanted ticked, in particular dealing with trees, and RDK were very helpful and patient in navigating these issues. They took the lead, acted as the middle man, dealt with the council on my behalf, helped me to understand what the council wanted, why, and how we were to complete what was being asked for. With the design, they took on board what we wanted, allowed us to change our minds, happily redesigned plans and done this until we were happy with everything. They responded to emails promptly, answered or returned calls quickly, took the time to explain parts of the process, and answered my many questions. They have made it clear they will be committed and available to us until the completion of this project, which after the rocky road so far, makes me feel much better! I will use them again in future, and recommend them to anyone who needs help in designing a building and obtaining planning permission for it.

Did plans for our dormer lift extension and were brilliant. Came up with some great plans, responsive to our requests for tweaks and in good communication throughout. As often happens with ambitious projects, the council rejected the first iteration, but RDK were knowledgeable in how to make minor adjustments that led to a successful second application. Couldn’t recommend more highly!

Professional service rendered. RDK Civil Engineering were very quick to respond to our request and were able to secure a successful application at first attempt. Definitely recommend their services, and also to add, they are quite affordable and fair in their pricing.

2 projects (raised steel deck and oak garage) completed with structural calculations done and passed by building control. This was done retrospectively as part of a regularisation certificate for building works already completed. Great result that we now have our certificates received. Many thanks to Ranga and Sasith for their work.

Simple and straightforward packages which are affordable with no hidden costs. Good communication and quick to respond to changes. Very happy with the customer service, the survey was completed quickly and drawings produced. The incorporation of the structural engineers design and calculations included in this package instead of having to source in addition to the architect was really helpful and made plans and alterations a lot smoother.

Professionalism : Excellent service strongly recommend to anyone

Structural Inspection, Gloucester

Very happy with the service provided by Ranga and his team. They helped maximise our space reducing the need for a column in the middle of the room. They were speedy and efficient with the visit and production of the plans and the 3D rendering service was a plus. When the plans were reviewed by the steel manufacturer, he said it was the best and most details set of plans he'd seen in 30 years. Great job all round!
