About Us

Founded in 1992, A D Practice Ltd is a small, well-established and multidisciplinary Chartered RIBA architectural practice located in The Mill, Wheathampstead, Hertfordshire. We offer a full range of design services including specialised planning advice and design development; initial feasibility studies; planning permission consents and appeals; building regulations; sustainable design; energy efficiency advice; contract administartion. We also offer Passivhaus design and are members of the Passivhaus Trust, the AECB (Association for Environment Conscious Building) and The Green Register. Our key strength is our ability to listen and learn from our clients and work together in order to create better spaces that both work for people and improve their quality of life. We design in BIM (Building Information Modelling) meaning that we can offer 3D visualisations of all our schemes, no matter how small, which can aid the understanding of the design for both clients and planners. Sustainability is at the heart of this philosophy and every design we produce. As members of several sustainable building associations and Certified Passivhaus designers, we design buildings that are healthy for both the planet and occupiers, using natural construction materials and renewable energy sources where possible, minimising the energy used by our buildings and setting them sensitively in nature to maximise natural daylighting and enhance local biodiversity. We have a varied client base from both the public and private sectors, commissioning bespoke and developer-led schemes. Completed work includes individual residential new-builds and developments; extensions and refurbishments; commercial schemes; conservation and listed building work; primary, secondary and tertiary level education projects; restaurant and retail fit-outs; ecclesiastical; healthcare and community projects.
