How We Work

Site Survey & Consultation

We begin with a thorough site survey and in-depth consultation to understand both your property’s constraints and your vision. Our architectural team measures your existing space, assesses structural considerations, and discusses your lifestyle needs, aesthetic preferences, and budget parameters to establish a solid foundation for the design process.

Draft Drawings Issued

Following your consultation, we create detailed draft drawings that balance your aspirations with practical and regulatory requirements. These initial plans include floor layouts, elevations, and key design features, providing you with a comprehensive visualization of how your completed project will look and function.

Revisions & Approval

We refine your designs through a collaborative feedback process, incorporating your suggestions and addressing any concerns. Our revision stage ensures every aspect of the design meets your expectations before finalization, with unlimited minor adjustments included in our fixed-fee service to guarantee your complete satisfaction.

Final Submission

Once your designs receive final approval, we prepare and submit all necessary documentation to local authorities, including planning applications and building regulations submissions. Our team manages the entire submission process, responding to any queries from planning officers and ensuring all technical requirements are satisfied for swift approval.

A good company to deal with. They responded swiftly from the start until the end and talked me through what I needed to do in regards to a through lounge at my property.
AC Design did the structural calculations for our single storey extension and also drawing for build over agreement. I can say the communication with Zubear was very smooth and professional. Everything was done on time and very professional. I would use them in future for sure.

I was looking for a cost competitive service for floor plans and structural calculations. AC Design Solutions provided a good quotation but I had never dealt with them before so was obviously cautious about conducting business totally online. I conducted some research and then instructed AC and have been impressed with the professionalism and attention to detail. I would recommend them and shall be using them for the next stage of my project.

We highly recommend AC Design Solutions who we used to design our 2 storey extension in a conservation area. We had looked at their previous work and spoken to neighbours who had previously used their services. As we live in a conservation area we wanted to hire someone who would not only understand the local requirements and regulations but also someone that had the experience and off course was reasonably priced.From first contact to final approval stage, Zaeem was extremely helpful and always made himself available to us.We highly recommend AC Design Solutions for any off your architectural planning and design requirements.
