Average rating: 5 out of 5 stars12 October 2025
“Working alongside Mary Maldé as a fellow professional is an insightful and joyful experience. I am consistently impressed by Mary's creativity and artistry. She brings a fresh perspective to design and the confidence to embrace projects that go beyond the ordinary. Mary's work reflects careful consideration of her clients' briefs. Her ability to skilfully apply the fundamentals within the design process helps achieve beautiful spaces that balance sophistication and functionality, as evidenced in her growing portfolio of work. It was especially a joy to collaborate with Mary on a soft furnishings project, where she infused her expert perspective on colour and unique style to jointly create beautiful bespoke pieces. Mary's communication style is warm and proactive, ensuring that those with whom she works understand her vision and are an integral part of the process. I'd gladly recommend Mary.”

“I recently had a kitchen and appliances installation done by NGUK Kitchens and I am absolutely thrilled with the results! From start to finish, the team was professional, efficient, and incredibly helpful. They took the time to listen to my preferences and provided expert advice on design and appliance choices. The installation was seamless, and the attention to detail was outstanding. My kitchen now looks amazing, and all the appliances are working perfectly. I couldn’t be happier with the service and would highly recommend them to anyone looking to upgrade their kitchen!”

Design and Build Company FAQs
In short, a design and build company consists of all stages of the construction process, from design to build, in one place. A design-build firm works under one contract with the project owner to complete both design and build steps of the project.

They will take on the responsibility of planning the project, drawing up the designs, costing, sourcing the building materials and supplies, building the structure, installing any permanent features and possibly advising on the interior design of your home; all while consulting you every step of the way.
Speed and cost. Hiring a design & build company for your Welwyn project means that the whole process from start to finish will be quicker, as all stages of the project will be handled by one company. This also saves time finding additional companies to complete certain stages of the project and potential back & forth between builders and designers to discuss the plans.

By using a design and build company in Welwyn for your project, you will also be given an all-in-one quote for the design and construction of your project. This is often cheaper than hiring separate professionals for each step of your project.
