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. ## Public review evidence (by source) | Source | Average rating | Reviews | | --- | --- | --- | | Houzz | 5.0/5 | 5 | ## Trades Architect, Builder ## Services they list _Listed on public sources or the business's own website; check directly that they cover your job before you book:_ - 3D Rendering - Accessible Design - Annexe Design & Construction - Architectural Design - Architectural Drawings - Building Conservation - Building Design - Custom Build Homes - Design Consultation - Drafting - Eco Homes - Floor Plans ## Awards & recognition - 3× Best of Houzz winner (2026, 2025, 2024) ## Verified work history - Planning applications: 1 planning application on the public register (Barnet), 2008 ## What we checked, and when _What MyTrustedTraders independently checked for this business (verified items only):_ - Review volume: MyTrustedTraders shows 5 public reviews on this profile.

Ask for their ARB number and check it free at arb.org.uk. An 'architectural designer' or 'technologist' is a different, unregistered role (often capable, but not the same protection). - Agree how they charge before any work starts (a percentage of the build cost, a fixed fee, or an hourly rate) and exactly which stages it covers (concept design, planning application, building-regulations drawings, work on site), so there are no surprises later. - Confirm what they will actually handle versus what is excluded (the planning application, the building-control drawings, and whether they will administer the builder's contract on site), and get it, and a portfolio of similar projects, in writing. - Ask to see a portfolio of completed work like yours, plus recent references you can contact. - Check the credentials and registrations that matter for this work, and that they are current. ## Contact - Phone: 01582 834361 - Website: https://www.adpractice.co.uk --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/a-d-practice-ltd-2 Real public evidence only: every figure traces to a named source, with evidence held from 2 named public sources.
