CSL Architecture is the trading name of Christopher Sharp Limited, a CIAT Chartered practice delivering healthcare, residential and commercial projects across Hampshire and the wider south of England — from early feasibility through to Building Regulations and site delivery.
CSL Architecture is the trading name of Christopher Sharp Limited (company no. 10993821, incorporated 2017), led by a Director who is a Chartered Architectural Technologist (MCIAT) and a registered Principal Designer under both CDM 2015 and the Building Safety Act 2022. The practice brings a background spanning residential design, commercial fit-out and large-scale NHS capital projects.
Every project is led by someone who understands the building physics and construction detail as well as the design intent, which means fewer surprises between concept and completion. The practice delivers BIM information management to ISO 19650 as Lead Appointed Party — giving clients a technically rigorous partner for both private and public-sector work.
Site appraisals, options studies and early massing to test what a site or building can realistically support before you commit budget.
Drawings, design & access statements and negotiation with planning officers to secure consent for extensions, new build and change of use.
Detailed technical packages that contractors can actually price and build from, including BIM information management to ISO 19650 as Lead Appointed Party.
Department reconfiguration, decant strategy and clinical space planning for NHS Property Services and healthcare providers, including Community Diagnostic Centres.
Extensions, renovations, guest annexes and new-build homes, sensitive to existing character and materials.
