1 stop design saved us!

1 stop design are brilliant! We are in a conservation area and they got our attention extension plans approved. They also did our structural home buyers survey before we bought the house and because their service was so good we got them to do our architectural plans. They do everything in house which is amazing! We are now awaiting the construction quote from them and will be keen to use their build team for the actual works. Thanks again! A special mention to Andrew and Alex who have seen the whole process through. More...

I was recommended Andrew by a friend and I couldn't be more happy with the service. It was a simple wall removal that became complex due to site issues.
Yet the engineering team at 1 Stop resolved all issues for us very smoothly and helped us reach a solution quite fast.
Thank you for your help and exceptional work.

Architectural Design & Planning
Architectural design is the process of planning and creating a building or structure that is both functional and aesthetically pleasing. It involves understanding the needs of the client, the constraints of the site and the environment, and the technical requirements of the building.
The architectural design process typically involves several stages, including conceptualisation, schematic design, design development, construction documents, and construction administration.
Structural calculations & Structural drawings: Structural drawings
These drawings show the layout and design of the building's structural elements, such as beams, columns, and foundations. Structural calculations are used to determine the load-carrying capacity of a structure such as a building, bridge, or other infrastructure. These calculations involve determining the stresses and strains that the structure will be subjected to under various loads, and then determining whether the structure is capable of withstanding those loads.
Building Regulation Drawings:
Building regulation drawings, also known as construction drawings or working drawings, are technical documents that detail the construction and design of a building. They are typically used to obtain regulatory approvals and to guide the construction process.
