Independent building consultancy for developers, funders, and property owners across London and the South East. RICS-qualified, commercially grounded, and genuinely invested in your project's success.
Crestmark Building Consultancy was founded to offer the kind of focused, senior-level advice that's often hard to find in larger practices. Every project is handled personally — with the depth of experience that comes from over a decade delivering complex schemes for major clients.
Based in Berkshire and regularly working across London, we're accessible, responsive, and straightforward to work with. No unnecessary layers, no junior handoffs — just sound professional advice when you need it.
We understand that projects live or die by programme and budget. Our advice is always grounded in practical, commercial reality — not just textbook theory.
As an independent consultancy, you deal directly with an experienced chartered surveyor throughout — not a junior assigned to your account.
We're straightforward to work with and build lasting professional relationships. Many clients come back because they know what to expect: good advice, delivered honestly.
From inception to completion, we provide the full range of building consultancy services that developers and property owners need.
Buying a home is one of the biggest decisions you'll ever make. We believe you deserve a survey written for you — not a tick-box report that leaves more questions than answers.
We only carry out full building surveys. Unlike the rigid Level 1, 2 and 3 format, our surveys are tailored to the property in front of us — giving you a clear, honest picture of what you're buying, what needs attention, and what can wait. No jargon, no unnecessary alarm, just the information you actually need to proceed with confidence.
End-to-end project leadership from feasibility through to handover. We manage programme, cost, quality, and stakeholder relationships so your project stays on track.
Robust contract management protecting your interests throughout the build. Experienced across JCT and NEC forms, with a clear head for disputes and variations.
Thorough condition surveys, pre-acquisition due diligence, defect diagnosis, and schedule of condition reports. Honest, evidence-based assessments you can rely on.
Fulfilling the Principal Designer duty holder role under the Building Safety Act for higher-risk buildings, ensuring design compliance and a coherent golden thread of information.
Managing pre-construction health and safety obligations under CDM 2015. Practical, proportionate, and integrated into your design and procurement process from day one.
Sensitive, knowledgeable advice for works to listed buildings and structures in conservation areas. Experienced in navigating listed building consents and heritage requirements.
We're not the biggest practice in the room. We're the one that picks up the phone, knows your project inside-out, and gives you a straight answer.
No parent company, no cross-selling. Our only interest is giving you the best possible advice for your project.
Over a decade of hands-on delivery across complex commercial and mixed-use schemes, with major consultancies including RLB, Atkins, and Faithful+Gould.
You won't be passed to a junior or left waiting days for a reply. We're available, engaged, and responsive throughout the life of your project.
We tell you what you need to hear, not just what you want to hear. Clear, honest, professional guidance — every time.
Whether you need full project management or a one-off survey, we're flexible — no minimum engagement, no overhead you're paying for unnecessarily.
We work with a focused range of clients where our expertise makes the most difference — typically developers, funders, and property owners with commercial or mixed-use assets.
Whether you have a live project, an upcoming opportunity, or just want to sense-check an idea — we're happy to have an informal conversation with no obligation.
