01Executive Summary

To the Epson
Project Team.

Thank you for the opportunity to present our proposal for Sucy-en-Brie.

This is an ambitious project. The November 2026 handover date, the mezzanine structure, technical demonstration areas, landlord approvals and operational dependencies all demand careful control from the outset.

The best projects are not defined by the absence of challenge. They are defined by the quality of the decisions made early, the clarity of the programme, and the discipline with which risk is managed.

That is the basis of our submission.

We have focused on the areas that matter most: protecting the programme, coordinating the technical detail, maintaining cost transparency and creating a clear route to a fully operational handover.

Our view is simple: Epson's objectives are achievable, but only with early alignment, decisive governance and close control of the critical path.

The following pages set out how we propose to deliver that certainty.

03 / Why Us
V.
04Why Voltarra

Epson's partner to guarantee successful delivery.

01
Critical path already de-risked.

Three mezzanine suppliers have already been tendered. A preferred contractor has been identified and structural design activities have been commissioned at our own risk to protect the September installation window.

02
Already an approved Epson partner.

Voltarra is already onboarded within Epson's procurement and compliance systems through ongoing projects in Paris, allowing immediate mobilisation without additional supplier approval processes.

03
Local permitting expertise in place.

Bush & Associates bring deep local knowledge of Sucy-en-Brie and the wider Val-de-Marne region, helping navigate planning, approvals and statutory processes with greater certainty and speed.

04
Design continuity secured.

Lena Sabela remains involved as Strategic Design Advisor, providing continuity between the original design vision and technical delivery whilst ensuring Epson's operational and workplace objectives remain protected.

05
Supply chain already validated.

Every major contractor has visited site, reviewed the scope and submitted live project-specific quotations. Costs, programmes and technical solutions are based on real market engagement, not desktop assumptions.

06
Value identified before appointment.

Cost-saving opportunities have already been explored across procurement, programme and infrastructure reuse, allowing Epson to benefit from value engineering before contract rather than after.

  • 01Letter of Intent issued immediately following award to enable mobilisation and early procurement activities.
  • 02Mezzanine package released within one working day of LOI approval to protect the critical path.
  • 03Mezzanine surveys, technical design and fabrication commenced ahead of the main construction contract.
  • 04Bureau de Contrôle, SPS coordination and statutory approvals progressed in parallel with design development.
  • 05Commercial negotiations and contract execution run concurrently with technical mobilisation activities.
  • 06Long-lead procurement protected from contract execution timescales, removing the principal programme risk.
Critical Dependency

The mezzanine structure remains the primary programme driver. Failure to authorise the mezzanine package by 18 June 2026 will directly impact fabrication release, installation sequencing and the planned December 2026 handover.

07Project Delivery

A note from your
Technical Lead.

To the Epson Project Team,

I have spent the last fifteen years delivering industrial, workplace and technical fit-outs across France — including programmes of comparable complexity to Sucy-en-Brie. From mobilisation through to handover I will own technical delivery end-to-end: design coordination, constructability, MEP integration and statutory compliance.

My focus will be uncompromising on three things: protecting the January 2027 launch date, holding the supply chain to the standards Epson expects, and giving your team complete visibility of progress, cost and risk every week. There will be no surprises.

I have already walked the building, met our preferred mezzanine partner on site, and started conversations with local authorities alongside Bush. The team is ready.

Sincerely,

Guillaume Galland

A note on our
commercial approach.

Before reviewing the figures that follow, I would encourage one simple question:

"Which commercial approach gives Epson the greatest confidence in the outcome?"

In our experience, the most successful projects are not those that begin with the lowest number. They are the projects where the right decisions are made early, risks are understood openly and investment is directed to the areas that matter most.

That principle has shaped this submission from the outset.

Every cost has been challenged. Every major package has been reviewed. Every opportunity to reduce risk, improve value or protect programme has been explored before being presented to you.

The result is a commercial submission designed to provide transparency, clarity and informed choice — not simply a tender sum.

Our objective throughout has been straightforward: to approach Epson's investment with the same care, scrutiny and responsibility that we would apply to our own.

I hope the detail that follows reflects that commitment.

09Design Approach · Voltarra × Bush

A design partner chosen
for this brief.

One of the earliest conclusions reached during our review of the project was that Sucy-en-Brie would benefit from a delivery team that combined European project leadership with specialist local French technical expertise.

Whilst Voltarra regularly delivers complex workplace, industrial and technical environments, the combination of French statutory approvals, structural mezzanine integration, detailed MEP coordination and an accelerated programme creates a level of complexity that warrants dedicated local technical support from the outset.

For that reason, we have partnered with Bush & Associates, a French architectural and engineering practice with extensive experience delivering technically complex projects within the French regulatory environment. Importantly, this is not a new relationship. Members of the Voltarra team have successfully collaborated with both Derek Bush and Neege Allen on previous projects and have first-hand experience of their technical capability, responsiveness and construction-focused approach.

Rather than operating as an external consultant, Bush will form an integrated part of the wider Voltarra delivery team. They will report directly through Max Parsons and work alongside our project, commercial and delivery teams, with direct technical access to Office Principles and Lena Sabela to ensure continuity of the design vision, brand standards and interior design intent established for Epson.

The result is a single, coordinated delivery team that combines local French expertise with wider European project leadership — reducing risk, improving technical coordination and providing greater confidence through design development, permitting and construction.

09Who is Bush & Associates

Four decades of delivery
in Paris.

Bush & Associates was founded in Paris by Derek Bush, who moved from London in 1973 to work alongside Terence Conran. He has run his own design practice since 1989, leading one of France's largest interior contractors during his first decade in the country and qualifying as Interior Architect with the CFAI (Ordre des Architectes d'Intérieur).

In 2025, Derek was joined by new partners Timothy Shepherd and Neege Allen, adding operational depth and links to associated practices in London and Milano. Together they form a diverse, multicultural group built around precision, clarity and brand-driven design — delivering workplace, flagship retail, hospitality and high-end residential at scale.

Recent and current work includes TBWA Paris — a workplace transformed into a future-facing creative hub due for completion early next year — and a prestigious HQ programme for OMG, transforming staff experience across the agency's own walls the way Bush does for its clients.

"Our unmatched track record in project delivery, combined with Timothy and Neege's international expertise and the creative talent of our teams, sets the stage for the next chapter in our growth."

09Permitting Strategy

Permitting strategy.

One of the key advantages of incorporating Bush & Associates into the delivery team is their experience navigating the French approvals process and coordinating directly with local authorities and technical stakeholders.

Based on the current scope, the principal approval pathway relates to the mezzanine installation and associated modifications to the existing building.

The proposed strategy is to commence permitting activities immediately following appointment, running in parallel with technical design development to protect programme certainty.

Key activities include:

  • ·Review of existing approvals and landlord requirements
  • ·Coordination with Bureau de Contrôle
  • ·Preparation of supporting architectural, MEP and technical documentation
  • ·Submission of applicable declarations and authorisation requests
  • ·Ongoing authority liaison and response management
  • ·Integration of approval comments into the Stage 4 package

Indicative approvals duration

Standard permitting route12 weeks
With Bush & Associates onboard8–10 weeks

~2–4 weeks saved through local authority relationships & parallel working

By engaging local technical specialists at the outset, permitting progresses alongside design development rather than becoming a programme-critical activity later in the project lifecycle.

10Who Are Voltarra

European design,
engineering and
construction.

Voltarra Group delivers complex workplace, industrial and technical environments across Europe through a single integrated delivery model.

Unlike traditional design practices or project managers, we combine strategy, design, engineering, commercial management and construction delivery under one team. This enables faster decision-making, greater accountability and clearer alignment between cost, programme and technical outcomes.

For Sucy-en-Brie, we have assembled a project-specific team combining Voltarra's leadership and delivery expertise with specialist local French architectural, engineering and permitting capability. The result is a single team focused on one objective: delivering a fully coordinated, construction-ready solution that can be procured, approved and delivered with confidence.

At the heart of our approach is Backbone™ — our methodology built around early contractor engagement, proactive risk management, programme certainty and complete commercial transparency.
