Eclectic Architects in Welwyn, Hertfordshire, UK

“We are absolutely delighted with the work completed on our side return kitchen extension by My Extension PM ltd. The quality of workmanship was outstanding throughout, with every aspect finished to an exceptionally high professional standard. Gosia was fantastic and a huge help with the design process. Her advice, creativity, and attention to detail made a real difference and helped bring our vision to life. Piotr was simply brilliant from start to finish. His project management, communication, and attention to detail were second to none. He oversaw every stage of the build with incredible professionalism and care, ensuring everything stayed on track and was completed to the highest standard. The daily catch-ups with him were invaluable—we always knew exactly what was happening, any questions were answered immediately, and we felt completely confident that the project was in safe hands. His dedication, organisation, and genuine commitment to delivering the best possible outcome really set him apart. The entire team was reliable, hardworking, and a pleasure to work with. We couldn't be happier with the result. We would wholeheartedly recommend them to anyone considering a building project and would not hesitate to use them again in the future. Thank you all, and especially Piotr and Gosia, for such an exceptional experience.”

“Marek has excellent sense of colour and fantastic design ideas. Very friendly as well. Can tailor outcome to various range of budgets/needs.”

“We are in the final stages of revamping a recent purchase in Nice, France working with Mark and his team at Callender Howorth. It has been a delight to work with Mark and his associates. At each step of the way, Mark, Nathalie and Jade have been nothing less than professional, competent, and really a delight to collaborate with. They have found really lovely and unique pieces that make our place sparkle. The construction work that has been done so far (a bathroom refresh, painting and repairing plasterwork and walls, electricity, etc) all have been to the highest standards. We are looking forward to seeing the final completed project and to settle in to our new place. We would not hesitate to recommend Callender Howorth for your design needs.”
