At Wilson Architectural Building Designs, we have over 25 years of experience working on various projects to enhance our clients’ way of life. We guide you through the entire process, from start to finish, ensuring that you are completely satisfied with the outcome. Unlike other companies, our services go beyond design. Our goal is to share our experience and help you benefit from it.

We work daily on building projects and are equipped to handle any situation that may arise. We welcome the opportunity to discuss your project with you.


You’ve got your plans and planning approval, now it’s time to find your trusted construction professionals.
We’ll guide you through the various steps and complete parts of the process on your behalf:


Third-Party Services are compulsory to every build and must be addressed well before you start building. We set up everything that you will need to have in place ahead of your build. This includes Thames Water build over agreements, Health & Safety CDM, structural calculations, building control services and party wall matters. We know what services you need from day one and can advise on all.


Whilst you are waiting for planning consent we recommend you find your building contractors. If you are a domestic client we can provide a builder’s questionnaire for contractors to fill in. If followed, this document will ensure your building meets expectations and safeguards your investment. The questionnaire ensures good communication so both parties know what to expect from each other from the outset. It contains valuable questions that need to be answered by your potential Building Contractor and includes templates of work schedules, payment plans. This is in addition to a tender and isn’t offered by other architectural designers, allowing you to make an informed decision.


We can advise you on the tendering process, giving you the support you need to ensure you are fully informed before you instruct your building contractor. We can also provide guidance and advice on products such as bi-fold doors, kitchens and bathrooms, so you can be sure you know what you are getting from the start.


The build begins, and your project starts coming to life. Unlike many other architectural designers we continue working with you through this part of the process to give you added confidence.


Big building projects can be daunting for anyone. We understand the construction industry and will conduct site visits during the build, checking that your project is running to schedule and your contractors are sticking to your plans. This helps ensure the quality of your build.


Having major building work carried out on your property is never easy, and you might feel like you’re losing track of the many details. We help keep an eye on progress and we will be happy to examine a builder’s schedule of works and ask technical questions on your behalf.


During our site visits we will ensure that contractors are working safely and respectfully on your property. This helps to protect your property and possessions. We have 25 years of experience in the construction industry so we will hold your contractors to account.

Architectural drawings for three story extension.

“We were very pleased with Terry’s services. The drawings were very good and incorporated all of the points we asked. In addition, Terry provided very useful suggestions on how we could make best use of the new areas. The planning process was smooth, and Terry has been in touch throughout the build undertaking both site inspections and checking in with us to ensure we are happy with the work being undertaken by our builders. I would not hesitate to recommend Terry’s services.”

Drawings and planning permission.

“The drawings were of high standard and Terry has been very precise and honest from the first day. Terry has always been happy to reply to our endless questions and has followed our works until the very end. We had many problems with our builder who wouldn’t turn up and demanded advanced payment to a point where we had to make a detailed payment plan. With Terry’s help we were able to have the works done within the extended deadline by making sure that what was owed to the builder was more than the value of the work left to do. This made the builder want to come back.”

Architect services for annex build.

“Terry Wilson was the architectural company we used for an annex we wished to build. He helped with the design and provided drawings, plans etc and made all submissions to the local authority. Planning permission was received first time, He then helped us through the setting up of third-party services needed. He advised and supplied a builders’ questionnaire, which was a great help in deciding which builder to use and useful during the build. Terry was on hand for any queries and paid visits to the site. All in all, the build ran smoothly and efficiently. We would happily recommend Terry Wilson to anyone.”

Plans drawn up for new extension.

“I cannot recommend Wilson Architecture enough. Terry has been with us through the whole journey of our build from discussing ideas, to drawing up plans and walking us through the minefield of steps that need to be taken when carrying out such a big project. Terry has always ensured that we as a client have been considered at every step of the way and has played a very hands on role in the whole process. He has always been on hand to answer any questions and provide advice. Terry has also been very supportive when we incurred difficulties with the build and was able to mediate the situation.”

Customer in Welling

Creation of a set of plans for a second story extension and redesign of living space on the first and second floors.

“Terry is very friendly and approachable, yet extremely professional, and has lots of excellent advice and ideas. He made the whole planning process very easy, and his drawings and designs were of a very high standard. He offers support throughout the whole project and while we haven’t needed him very often since building began, when we have asked for his advice and support he has been quick to come around and quick to take the initiative with any niggling issues. It is very comforting to know he is on hand throughout and very approachable.”

Customer in Orpington

Drawing plans for extension and interior modifications.

“Terry went through various options for the extension, suggesting different ideas; this was extremely helpful as we had no prior experience of building work. The final plans were very detailed and exactly what we required. Terry helped us considerably with gaining planning permission and selection of a builder. He was involved from start to finish in the project. Terry made the whole process very straight forward and we have ended up with an extension that we are thrilled with.”

Customer in Bromley

Single Rear, Double Side Extension and Internal Alterations.

“Our experience to date of working with Terry has been excellent. He is very professional, responsive and also very personable. We had actually engaged another architect but were not satisfied with our progress, so I had contacted Terry informally. Terry was available and immediately understood our requirements, so we decided to continue our project with Terry. From the onset Terry was able to propose an innovative and workable solution to a constraint which we had been unable to find an agreeable solution to previously. Terry was able to provide useful advice on the planning process and also to suggest cost effective solutions for the project. We met with a number of architects and felt that Terry was genuinely interested in our requirements and proposing innovative and interesting solutions as opposed to just doing the standard, meanwhile always with an intention to save money on the build. My partner and I both work full time and have young children, so Terry’s availability to come to our house in the evenings at no extra cost has been invaluable. The all-inclusive quote received for the project was competitive and within that there was a generous allowance for amendments and changes at no extra cost. From speaking with a friend recently going through a similar process and hearing about the difficulties she has experienced with her architect solidifies the importance of having a good architectural company and the difference to the overall experience it can make. We are still going through the process but to date Terry and his team have been efficient, professional and pleasure to work with. We would recommend Terry with no hesitation.”

Customer in Chislehurst

Planning and building reg drawings for single rear extension and internal remodelling.

“Terry did a great set of designs, which he submitted for us to Planning and which were passed with no problems or issues. He gave us a huge amount of advice in selecting a builder, including a handy Builders Questionnaire. He also handled the building regulation drawings and made initial contact with building control. Terry kept in regular contact, made regular visits to the site and was a reassuring presence when needed.”
