For over 15 years, I’ve worked alongside architects, developers, and private clients to help deliver high-quality residential and mixed-use projects across London and the South East—bridging the gap between ambitious design and buildable delivery. Today, I lead Multiproject’s Fixed Price Cost Planning service—a specialist cost consultancy designed to help architects take control of project budgets early, without the overhead of full-scale QS services. Our Fixed Price Cost Planning (FPCP) service is purpose-built for small to mid-sized architecture practices working on: 📍 Private residential projects up to £2m 📍 Development schemes up to £5m We know the challenges architects face: • Clients pushing for accurate budgets too soon • Late-stage cost shocks leading to redesigns • Fee negotiations undermined by budget uncertainty We solve that with fixed-fee, fast-turnaround cost plans that provide clarity from the outset—helping you protect your design, build client trust, and keep projects moving forward. What we offer: 📐 Fixed-price Budget Estimates (RIBA Stage 1–2) 📊 Elemental Cost Plans (RIBA Stage 2–3) 📝 Schedule of Works (RIBA Stage 4) ⚡ Rapid turnaround, typically in 2, 7 or 14 business days respectively Whether you’re quoting a new project, preparing a feasibility study, or supporting a client through planning, we give you reliable numbers you can work with—without committing to a full QS scope. Let’s connect if early-stage cost clarity—or full-scope QS support—could help make your next project smoother. 📞 0204 578 1027 📧 [email protected]
