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.

Q. What structural engineering services do you provide, including BIAs?

Our structural engineering team brings extensive expertise across a variety of projects, from residential buildings to large, multi-storey developments. We specialize in:

Basement Impact Assessments (BIA): We conduct thorough BIAs to ensure compliance with planning and safety regulations, handling everything from single basements to complex triple-basement projects, even those with specialized features like pools.
Steel and Reinforced Concrete (RC) Frame Design: Our engineers design robust steel and RC frames with a focus on stability, safety, and protection against disproportionate collapse, ensuring long-lasting integrity.

Q. What’s the Difference Between an Architect, a Residential Designer, and CIAT ?

The roles of architects, residential designers, and Chartered Architectural Technologists may seem similar, but the differences are significant, especially when choosing the right professional for your project. Here’s what sets them apart:

Architects

Architects undergo years of academic and practical training. Their expertise lies in managing complex projects that require creative design. Architects are trained to prepare and submit construction documents for planning and building regulations, making them ideal for large-scale projects.

Residential Designers

Residential designers focus on simpler home projects, like interior layouts. Their training is less formal, often involving certificates or vocational programs. They’re great for creating cost-effective designs for smaller projects but lack the technical expertise. Think of them as specialists in making spaces look great without the engineering complexity.

Chartered Architectural Technologists (CIAT)

Chartered Architectural Technologists, like us at AC Design Solution, combine architectural creativity with deep technical expertise. We’re trained to understand not just how a building looks but how it performs. Registered with the Chartered Institute of Architectural Technologists (CIAT), we specialise in balancing design and science to deliver spaces that work seamlessly.

We bring:

  • Advanced knowledge of building performance and technical systems
  • Expertise in sustainable, energy-efficient designs
  • The ability to handle complex projects, including structural changes and compliance with UK regulations

Unlike residential designers, we’re qualified to submit building regulations applications and oversee the entire process from concept to completion. Our approach goes beyond aesthetics.

Which Professional Is Right for You?

If your project is a simple interior update or a straightforward renovation, a residential designer might do the job. But if you’re tackling bigger changes, advanced technical requirements, or sustainable solutions, you need the expertise of an architect or Chartered Architectural Technologist.

At AC Design Solution, we offer something unique: the creativity of an architect combined with the technical precision of a Chartered Architectural Technologist. Whether it’s a bespoke home or a high-performance commercial project, we make sure your design isn’t just visually stunning—it performs brilliantly, too.

Q. What structural engineering services do you provide, including BIAs?

Our structural engineering team brings extensive expertise across a variety of projects, from residential buildings to large, multi-storey developments. We specialize in:

  • Basement Impact Assessments (BIA): We conduct thorough BIAs to ensure compliance with planning and safety regulations, handling everything from single basements to complex triple-basement projects, even those with specialized features like pools.
  • Steel and Reinforced Concrete (RC) Frame Design: Our engineers design robust steel and RC frames with a focus on stability, safety, and protection against disproportionate collapse, ensuring long-lasting integrity.
Q. Do you provide party wall surveys and agreements?

Yes, we offer comprehensive party wall services, including surveys, agreements, and notices to ensure compliance with the Party Wall Act. Our team works with both building owners and adjoining neighbors to assess potential impacts and establish clear, legally sound agreements that protect all parties involved. From initial notices to final agreements, we guide clients through each step, minimizing disputes and ensuring a smooth process.

Q. How Successful is AC Design Solution at getting planning permission approved?

Securing planning permission is what we do best. When it comes to getting planning permission approved, our track record speaks volumes – we’ve successfully guided countless projects through the planning permission process, from straightforward home extensions to complex developments.

Our unique approach to planning permission sets us apart. We’ve developed a proven six-step strategy that consistently secures planning permission, even for the most challenging sites. Whether you’re dealing with conservation areas, listed buildings, or Green Belt restrictions, our team knows exactly what it takes to get your planning permission approved.

What makes our planning permission service different? We don’t just submit applications – we work closely with planning officers to understand exactly what they’re looking for.
