WHO we are
Calli Group is a design and construction advisory that partners with developers and builders at the point where project value is created or lost — before delivery risk impacts feasibility, pricing, margin or programme.
We operate at the critical juncture where design decisions carry their greatest commercial consequence. Our role is to interrogate those decisions early, ensuring they support approvals, procurement and construction outcomes — not undermine them.
Calli Group was established to address a gap in traditional advisory services, where design decisions are often disconnected from delivery and commercial reality. Our approach is independent, practical and experience-led, grounded in real-world architectural and Tier 2 / Tier 3 construction delivery.
We focus on early decision-making that:
Protects Capital Early - Identify risk before it becomes a cost
Unlock hidden Value - Improve feasibility, efficiency and buildability
Increase pricing and delivery certainty - Documentation aligned with construction reality
why calli group
We understand how projects are actually delivered—and how early design, approval and procurement decisions directly affect programme, cost, capital certainty and margin.
We operate where many advisors don’t:
at the point where feasibility meets approvals, approvals meet procurement, and design decisions directly influence pricing, buildability and returns.
Unlike traditional advisory, we assess design and documentation in context, not in isolation. Our focus is on how projects will be approved, priced, procured and built — not simply how they appear on paper.
Much of our work is delivered through targeted early design reviews and pre-tender audits, where assumptions are tested before they are priced, transferred or embedded on site.
Our advisory is not academic. It is commercially grounded, experience-led and proven in Tier 2 and Tier 3 delivery environments — focused on protecting capital, maintaining certainty and maximising value.
What this means in practice:
Early identification and reduction of approval, scope and coordination risk
Uncovering hidden design and structural value that supports feasibility and returns
Clearer responsibility allocation across consultants and trades
Documentation that supports accurate pricing and buildability — not disputes
Procurement clarity and pricing confidence before market engagement
Value realised before tender, not attempted recovery under delivery pressure
