Our Story

Carmen Austin Architecture LTD specialise in residential extensions and new builds, offering a stage-by-stage service to suit each client's own personal requirements

Carmen Austin Architecture LTD has been trading since 2012 and specialise in residential extensions and new build houses. We aim for our extensions to adapt your house to blend seamlessly into the existing without a change to the architectural style. On the other hand, if the aesthetics could be enriched by an overhaul, we are confident to carry out a full revitalisation of the appearance of your house.

As a registered, chartered architect, Carmen is able to take your project from the initial design and development stages all the way on to site, also providing contract administrative support when the project is under construction. Alternatively, if only a design is required we are very content to only carry out the project, stage by stage, as the client wishes. Carmen and her team have carried out an extensive number of projects in these past years, each with an individual design based purely on the client’s needs.

kind words

  • Professional, caring and so efficient.  Carmen helped us create a wonderful vision and it really has been a pleasure working with her and the wider team.

  • We selected Carmen after seeing three different architects, she was friendly, professional and keen to really understand exactly what we wanted from our loft conversion and renovation project.  Carmen came up with a design that was perfect for how we wanted to live and also sympathetic to the style of building. She helped us through the planning permission process, and also getting quotes from and selecting a builder to do the job. We were extremely fortunate that she could take on the management of the project for us, and while an additional cost, I'm certain we reaped the benefits many times over. She ensured we had clear consistent communication with the builders and building control officer throughout the project. She was meticulous in drawing up the specifications, and able to check that they had been completed at each stage. Her weekly meetings with us and the builder made sure the time lines didn't slip and that any unexpected costs were properly quoted for and signed off at each stage.  We cannot recommend her highly enough, she is a great person to work with, an excellent architect and a fabulous project manager. Thank you for our beautiful home! Jemima
  • Carmen picked up our project at a very stressful time. She was patient, professional, easy to deal with – but with an incredible eye for detail.  Her specification was excellent and we were so impressed we asked her to project mange the whole project. Carmen was diligent, detailed, kept us informed every week and enabled the project to be delivered to specification, to time and to budget (barring the changes to specification that we made). Carmen turned around our project and we are absolutely delighted with the results and very happy to recommend her work. A. Hutchinson
  • Carmen was extremely professional, kept our project fully on track and also controlled costs. Her suggestions during the project, for instance simple things like glass shelves to let the light through and a dramatic glass splash back, changed our kitchen from great to extraordinary. Carmen is also great to work with on a personal basis, easy to talk to and genuinely cares about the work. S. Mocatta
