DECON managed the fit-out of this prestigious jewellery destination, where detail and craftsmanship are everything.
The project required an exceptionally high standard of finish, close coordination with specialist joinery and display contractors, and careful management of a landlord relationship in a prime central London location.
⸺ Programme management
How we keep every restaurant, retail, or leisure rollout on time and on budget by coordinating multiple site builds as one connected pipeline rather than a string of standalone projects.
⸺ Full project management & cost consultancy
We run your build end to end, design, budgeting, procurement, site delivery, and cost control, under one team, so you get a single point of accountability for scope, programme, and spend.
⸺ Technical Management & Support
We handle the specialist, behind-the-scenes detail, statutory compliance, technical design queries, and contractor coordination, so nothing trips up your build once it's on site.
⸺ Estimating, cost management & value engineering
We forecast your build costs early, track spend against budget throughout, and find smarter ways to hit the same design intent for less, keeping your project financially on track from day one to handover.
⸺ Procurement, tendering & supplier management
We source and vet the right contractors and suppliers, run a competitive tender to secure the best price and terms, then manage those relationships through delivery so quality and timelines hold.
⸺ Contractor liaison
We sit between you and the people on site, day to day communication, resolving issues, and keeping contractors accountable, so you're never chasing updates yourself.
⸺ Construction oversight & delivery management
We're on the ground managing the build itself, tracking progress against programme, quality-checking work, and solving problems as they arise, so the project lands on time and to spec.
⸺ Pre-construction
Is everything we do before ground is broken, feasibility, design coordination, programme and cost planning, so your build starts on solid footing and avoids costly surprises once on site.
⸺ Value engineering & quality assurance
We refine the design and specification to save cost without compromising the finish, then check the work delivered actually meets that standard throughout the build.
⸺ Landlord liaison
We manage the relationship and approvals process with your landlord, licence to alter, works schedules, sign-off, so your build stays compliant with lease terms and doesn't stall waiting on permissions.
⸺ On-site Construction / Handover
We oversee the physical build through to completion and manage a smooth handover, snagging, documentation, and sign-off, so you walk into a fully finished, ready-to-trade space.
⸺ Post-completion
We stay engaged after handover, resolving snags, defects, and any outstanding items, so your space keeps running smoothly once you're trading.
