There is still a tiny bit more work to do before the propery is complete (namely applying the crisp white exterior.) However already we can see what an improvement the new living space has made for our clients. If you're thinking of embarking on a similar project, we'd love to get involved.

Case Study: Langstone Residential Extension




Our clients approached us looking to create a sympathetic double storey extension to their cottage home. Having already being in possession of a design they were happy with, we were instructed to oversee the project works. We implemented the RIBA domestic works contract between our clients and their chosen contractor, Fern Bay Properties, ensuring over five seperate site visits that all work was being completed safely and adhered to both building regulations and the client's original plans.

We regularly undertake a range of commissions varying in scale and complexity. We can take on 'Full Service Appointments' which run from conception to completion and we are also happy to assist clients in any isolated project stages. If you would like to talk to us regarding your own scheme, please contact the team today to book a free consultation. 




There are a number of ways a person may seek to find an architect – most commonly through word of mouth referrals, via search engine sites or by asking on social media for recommendations. If using the latter how do you know which firms are competent and reliable to do the work you need, in the way you imagined? 


Our top tips for choosing an architect!

- The first necessary step is to check they are registered with the ARB. (Architects Registration Board). The ARB was set up by the government to keep an official register of all individuals and practices who are legally entitled and qualified to use the patented term ‘architect’. You can check the architects register here –

- Whilst not a necessity we strongly advise using a RIBA (Royal Institute of British Architects) Chartered Practice. (Click here to read why you should a choose a RIBA Chartered practice.)

- Thinking about your project do you need a specific skillset or service? For example, if you are working on change of use scheme it would be beneficial to choose a practice which can demonstrate experience within that sector. We recommend asking how many projects of that type the practice has worked upon, if there are any finished buildings you can visit or if they can supply a contact for testimonial.

- Put together a shortlist of architects to speak to in person about your plans. Most firms will offer a free consultation or initial discussion. This is a great opportunity for architects to demonstrate their creative ideas and   general enthusiasm for your project.

- Ask the practice for their track record with approvals – try and suss out if they have a good relationship with local planners.

- The fee proposal – don’t necessarily go for the cheapest bid. Weigh up everything you have learnt about your potential architect so far. A good practice will always devote time to explaining their fee proposal and         clarifying any points you may be unsure of.

Richard Andrews discusses his vision for Newport City following 2018 Summit meeting

Following the Newport City Summit 2018 meeting that was recently held at The Celtic Manor Resort, our director Richard was interviewed by new South East Wales publication 'The Business' to discuss how we would approach the major changes soon to come to our city! Great magazine, highly worth a read!



Extensions Part 2 – A Residential Case Study

Richard Andrews Architects, Residential Extension

Following the last post in our ‘Design in winter / build in summer’ campaign, we’re back with the second instalment. Showcasing one of our favourite residential extensions from the past year as a case study, we talk you through our three stages of work with step by step images from the initial design stage right through to completion.


THE BRIEF: To create a new single story extension to the rear of the existing property for family room / kitchen space.

Stage one – Planning & Designing

Our client wanted to create an airy and light cooking/ entertaining space that would maximise their views over the surrounding countryside. Following collaborative design meetings, we came up with a scheme that encompassed a large kitchen extension. We allowed room for an island to act as a casual seating area and to provide further food preparation space – with a more formal dining area to the side.  Opposite, we proposed a large orangery with an oversized roof light over a bright, relaxed, open plan entertaining area.

Stage Two – Detailed Design and Tender                                                    

Whilst Stage one is all about feasibility, planning and design – where we work with our client  to produce a number of design options for their project and supporting them through any planning applications, stage 2 is where we apply our detailed understanding of construction and regulations to the drawings, to provide a comprehensive package for builders to work from that meets all the requirements set out in building regulations.

For this project we administered a tender package to several building contractors to get the best price and quality for the build works. In this instance our client chose to work with Tim and his team at TLC Building Services.

Stage Three – Contract and Project Overseeing

With TLC Building services now on board, we administered a contract between them and our client. This contract was based on our detailed drawings, our understanding of construction laws and contract negotiation. We oversaw all the building works onsite to ensure the work was delivered in line with our drawings, regulations and was the standard allowed for in the original tender.

Progression of work…

The building contractors began to dig the foundations for the new extension to which the drainage, pipework and any other services needed to be laid. All work required signing off from a buildings control inspector, following which the concrete footing needed to be poured into place and again approved by building control.

Next, the builders turned their attention to damp-proofing. This can be achieved in several ways, such as through a damp-proof course, damp-proof membranes or integral damp proofing. Following this step is an exciting stage where we see the framework of the new build coming to life. Below we can see the creation of the block and brickwork, with wall ties fixing the walls together. The contractor was busy making sure that the cavity walls were insulated and that the lintels for doors and window spaces were fitted correctly. Following which the builder began to assemble the internal walls and lay a floor screed.

At this point the contractor constructed the roof structure and completed the rafters which were fitted with membrane and covered with our client's choice of material – roofing tiles. The contractor also started work on fascia’s, guttering, drainpipes and soffits.

The next step was to add the doors and windows into the framework, complete the internal plumbing and electrics.  It was at this stage where stud walls were erected and internal insulation fitted before plastering. Following this stage, the new kitchen and flooring was also completed. Our client chose to render the exterior of the property to match beautifully with the original part of the house.

With building work completed our clients received a final certificate of approval from the building control officer. After which all that was left to do was relax and enjoy their new space!

What our client thought about the process;


I found RA Architects through a Google search and took a chance as the business was pretty new. I was immediately impressed by Richard's professionalism and his ideas. He listened to how we wanted to use our extension and came back with a number of options to talk through.


Once we had agreed a design and a cost Richard and Lewis took away all the pain – they drew up the planning application produced the tender documents and sourced a number of contractors for us to meet and submit a tender. It was reassuring to know that the people tendering were approved by Richard and had all the necessary insurances and track record in place. We decided upon TLC Building Services in Cardiff and we couldn’t have been happier. Tim and his team were the perfect fit for us and we would have no hesitation in recommending them to anyone. They worked tirelessly to build an extension we love and did so in good humor- they were a joy to have around. Richard and Lewis visited at regular intervals to inspect the project, again taking away any stress.


Throughout the process RA Architects exceeded our expectations and I will use them again for any future projects I undertake.’
