Transforming old spaces into beautiful new places.


Your project timeline comprises three main stages, Consultation, Quotation and Services, and we’ll be with you every step of the way. For a more detailed breakdown of our processes, click on the link below.



This is where we get to know each other – we’ll explore your ideas, your requirements and your property, and you’ll learn more about us, the way we work, and how we can turn your dreams into a reality – and with our friendly, straightforward design team ready to listen, we’re confident we’re going to get along!



We’ll pitch you our initial design along with a personalised welcome pack and closing statement and open up a discussion about how best to achieve your home goals. We strive for perfection in everything we do, so we won’t move ahead until you’re 100% confident in our team, our plans and our processes.



This is where you sit back, relax, and let the magic happen. We’ll guide you through any paperwork or admin required and keep you updated and worry-free throughout the construction and development stages, until it’s time for you to step into your transformed space and start making some memories!


We offer three standard packages with varying levels of service and finish, meaning we can work with you to achieve your dreams, without breaking your budget.


Do you have a simple project in mind? Our Basic option includes your initial survey, plans and elevations and assistance with your planning and building regulations submissions in a package that’s budget friendly without sacrificing safety, communication or quality.


Our standard package is our most popular option, including all the basic services plus additional drawings and plans, 3D modelling, amendments and modifications, and a second site visit/inspection - peace of mind for you and your project.


Looking for another level of service? Our Premium package includes interior and exterior 3D modelling, electrical, structural and construction plans, highly detailed drawings and the tools to project manage the development. We provide various additional site-visits and inspections throughout the project to assure quality control.

“Hayden and the team were really lovely and helpful. He had some great ideas about what could be done within my budget and helped me make an informed decision. Definitely recommend HAC.”

Reading, UK

“Absolute amazing, I have the home that I’ve always wanted with the space required for my family. Everyone that completed the work were friendly and hard working. Highly recommend to anyone looking for work done to their property. I would use them again for future build and design work.”

Basingstoke, UK

“Hayden and the team were helpful and friendly throughout. They were always available for queried, and were very knowledgeable about local planning regulations. They listened to what we wanted and drew up very good plans based on our request, in a timely manner. We are very pleased with the service provided and would highly recommend.”

Reading, UK

“Hayden and the team were supportive throughout our Building Regulations Application, making a complicated process as painless and straightforward as possible. They frequently went beyond the call of duty and were impeccably patient despite our best efforts! It was a delight to work with them and wouldn’t hesitate to recommend them.”

Reading, UK

“HAC were recommended to me on a local Facebook group. I found them to be extremely professional, informative and very approachable. We were guided through the planning process, kept up to date with developments and were able to view the proposed outcome in an innovative way.”

Reading, UK

HAC Design & Build were great from start to finish. Right from the planning stage, communication was very good and any questions I had were answered quickly. The guys worked hard everyday, were very quick, tidy and can’t be faulted. They kept me informed through each stage of the project and would 100% recommend them.

Reading, UK

“We used HAC for the initial planning permission process. They are very prompt with their work and very accommodating to our changing ideas etc. and were honest with what we could and couldn’t have. The application of the planning permission was made almost straight away once the final design was agreed on. Planning permission took a while due to COVID-19 but no fault of HAC and the application went straight through without any questions which was brilliant. Would definitely recommend them and their prices were very competitive to others.”

Reading, UK

“The HAC Designs Team is highly recommended. Professional, efficient and cost effective.”

After undertaking an on-site consultation, we’ll be able to advise whether planning is needed. If you’d like to find out more, have a look at the Planning Portal website.
Upon validation of your planning application, a typical application requires 8-10 weeks for a decision to be made and communicated to you. Please see our process sheet for further information.
Absolutely – we carry out the submission of planning applications on behalf of our clients and liaise with the case officer throughout the duration of the planning process.
We aren’t, but we have long-term relationships with whichever trusted suppliers and professionals your project requires.
Subject to conditions, permitted development rights within residential dwellings allow certain works and changes that do not require planning permission. However, building control will still be required. To find out whether your project would fall under this category or not, an on-site consultation is encouraged.
