Building Regulations
Building regulation drawings go beyond the initial design — they include the detailed technical information needed to meet current building standards.
These plans cover key areas like structure, fire safety, insulation, and accessibility, giving your builder everything they need to carry out the work properly.
Our team is experienced in producing clear, accurate drawings that tick all the boxes for compliance and safety.
They not only help get approval from Building Control but also act as a practical guide on site, making sure your project is built correctly and to a high standard.

FAQs
How does the design process work?
Our design process begins with an initial consultation with your dedicated designer. We will discuss your vision, requirements and we will provide ideas for your design based on previously completed projects. From there, we move through conceptual design providing a first draft plan for your consideration. Following this we can revise the plans in any way you like to ensure you a completely happy with the design.
What is the typical timeline for a residential design project?
The timescale of a project differs, depending on the proposal. We can visit your property within a couple of days and have the first draft plans with you in roughly 14 days.
In some cases, building work can begin within a couple of weeks. In others, the timescale can be up to 4 months, depending on your project’s requirements.
