Why Developers Choose Kojo

We understand the pressures of development, programme, cost, compliance and quality. Here's how we protect your interests on every scheme.

Programme Certainty

We set realistic programmes based on what's actually achievable, and we hit them. You won't be chasing us for updates or managing slippage on your completion timeline.

Transparent Cost Control

No hidden variations, no unexpected extras. We agree costs upfront, track spend in real time, and flag any changes before they become invoice surprises.

Multi-Trade Coordination

One contractor managing all trades, no finger-pointing between subcontractors. We own the programme and the quality across every discipline.

Building Regulations Expertise

We've navigated Part A, B, E, L and M across multiple conversions. Your development will achieve Building Control sign-off without costly last-minute reworks.

Leaseholder-Ready Finishes

We build to sell. Finishes are specified to a standard that supports your marketing and satisfies the expectations of London's residential buyers.

Repeat Development Partner

Many of our developer clients return to us scheme after scheme. That trust is built on delivery, and it's something we protect on every project.

How We Work

A clear, transparent process from the first site visit to practical completion, so you always know what's happening and when.

01
Site Survey & Feasibility

We visit the building, assess the existing structure, understand your planning consent and architect's drawings, and identify any constraints before pricing.

02
Programme & Detailed Quote

We produce a fully itemised quotation with a phased programme, trade schedule and clear payment milestones, so you know exactly what you're getting and when.

03
Phased Delivery

Works are delivered to the agreed programme with weekly reporting. All trades are coordinated by your dedicated project manager. Variations are agreed in writing before proceeding.

04
Practical Completion

Building Control sign-off, full snagging, O&M documentation and a clean handover. Your development is ready to sell, let or occupy from day one.
