The interior design handover: What happens when your project is complete
At SP3 London, we believe the final stages of a project are just as important as the first. An interior can be beautifully designed and precisely built, but if the handover is rushed or poorly managed, the client's experience of receiving their space is diminished.
The interior design project handover is a defined process, not simply a moment when the keys are passed over. It involves snagging, final inspections, client walkthroughs, documentation and the transition into aftercare.
In this article, we explain what the design handover process looks like on a high-end project, what clients should expect and why this stage deserves the same level of attention as every other.
What is an interior design project handover?
The handover is the point at which the completed interior is formally transferred to the client. It marks the end of the construction and installation phase and the beginning of the client's occupation.
On a well-managed project, the handover is not a single event. It is a structured sequence that begins weeks before the client walks through the door. Snagging lists are compiled, outstanding items are resolved, documentation is prepared and the space is cleaned and styled to completion.
Through our Project Management and Design Management services, we manage this process to ensure nothing is left unfinished and the client receives a space that is genuinely ready.
Snagging and why it matters
Snagging is the process of identifying and recording defects, incomplete work or items that do not meet the specified standard. On a luxury interior project, snagging in interior design covers everything from paint finishes and joinery tolerances to lighting alignment and fixture installation.
We conduct snagging inspections methodically, working room by room with a detailed checklist against the approved design documentation. Every item is photographed, logged and assigned to the responsible contractor or supplier for rectification.
The standard we apply is the standard the client was promised. If a joinery shadow gap is specified at 3 millimetres, that is what we check. If a stone floor was specified with a honed finish, we verify it has not been installed with a polished one.
Final inspections and sign-off
Once snagging items have been addressed, we carry out a final inspection. This is a formal review of the entire space against the approved drawings, specifications and schedules.
Final inspections cover finished quality, mechanical and electrical systems, furniture placement, lighting scenes and any specialist installations. We also check that all items on the FF&E schedule have been delivered and installed correctly.
Only when we are satisfied that the space meets the required standard do we recommend sign-off. Our article on what a design manager actually delivers on an interior project explains how this fits within the wider delivery framework.
The client walkthrough
The client walkthrough is one of the most important moments in any project. It is the first time the client experiences their completed space, and the impression it creates sets the tone for everything that follows.
We walk the client through each room, explaining key design decisions, demonstrating any specialist systems and highlighting features they may not immediately notice. Lighting control systems, integrated technology, bespoke joinery mechanisms and HVAC controls are all covered.
This is not a sales presentation but it is a practical handover that ensures the client understands how their space works and feels confident using it from day one.
Documentation and maintenance guides
A completed interior comes with a significant amount of supporting documentation. We compile this into a structured handover pack that the client retains for future reference.
This typically includes:
FF&E schedules: a full record of every item, its supplier, warranty and care instructions
Material and finish references: so replacements or repairs can be matched accurately in the future
Maintenance guides: care instructions for specialist finishes, natural stone, bespoke joinery and upholstery
As-built drawings: updated drawings reflecting the final installed condition
Warranty information: details of contractor and supplier warranties and their expiry dates
This documentation protects the client's investment. Without it, maintaining the interior to the same standard becomes significantly harder over time.
Aftercare and post-completion support
The relationship should not end at handover. Through our Post-Completion service, we remain available to support clients after they have moved in.
This can include resolving any defects that emerge during the first months of occupation, coordinating warranty claims with suppliers, arranging seasonal maintenance for specialist finishes and supporting future updates or additions to the scheme.
For clients who engaged us through our Turnkey Interior Design service, post-completion support is a natural extension of the relationship. We know the space, the specifications and the suppliers, which makes aftercare faster and more effective.
Final thoughts on the interior design handover
The project completion stage in interior design is where attention to detail is most visible. A well-executed handover demonstrates that the same care applied during design and construction has been carried through to the very end.
Snagging, inspections, walkthroughs, documentation and aftercare are all part of a professional design handover process. Treating them as an afterthought risks undermining the quality of everything that came before.
