Interior design and fit-out in Lebanon: what should be coordinated before site?

Space planning should start with how the space will operate.

Furniture layouts, circulation, storage, customer flow, staff movement, equipment and accessibility all influence the physical plan.

For offices, retail, restaurants and hospitality spaces, operational requirements can affect doors, partitions, counters, back-of-house areas and service locations.

Locking partitions before these needs are understood creates redesign later in both the interior and MEP packages.

Coordinate MEP with the interior before ceilings and joinery are detailed.

Lighting, diffusers, sprinklers, detectors, speakers, access panels and other services often compete for limited ceiling space.

Joinery can also contain power, lighting, plumbing or equipment connections. These interfaces should be shown and coordinated before fabrication.

An attractive ceiling plan is only buildable when the technical systems above and within it have a realistic route.

Materials need technical and procurement decisions, not just visual approval.

A finish may be approved visually but still require substrate preparation, special installation, long lead time or maintenance conditions the client has not considered.

Material schedules should identify locations, finish codes and key performance requirements so suppliers and contractors are pricing the same intent.

Where substitutions are possible, the design team should define what characteristics must remain equivalent.

Custom joinery should be coordinated before fabrication drawings begin.

Built-in joinery depends on verified site dimensions, adjacent finishes, hardware, equipment, lighting and service connections.

Shop drawings are most effective when the design information already defines the intended geometry and interfaces. Using fabrication drawings to resolve the design itself pushes decisions too late.

Mock-ups or samples can be valuable for repeated or highly visible details before full production.

Fit-out programmes are often controlled by procurement more than labour.

Lighting, sanitaryware, hardware, specialist finishes, furniture and custom items may require decisions long before their installation dates.

A procurement tracker should therefore run alongside the design programme, showing approval, order and required-on-site dates.

This is particularly important where imported items are involved or where a commercial opening date creates little room for substitution.

Site support should protect design intent without slowing execution.

During fit-out, the design team should respond quickly to genuine site questions while avoiding uncontrolled changes communicated informally.

Critical samples, mock-ups and first installations can be reviewed before repeated work proceeds. This is more efficient than identifying a problem after an entire area is complete.

Final snagging should distinguish construction defects from owner additions or later design changes so closeout remains clear.

Define what must be frozen before each stage of fit-out begins.

Not every interior decision needs to be complete before mobilisation, but the project should know which decisions control demolition, partitions, first-fix MEP, ceilings, joinery fabrication, finishes and furniture.

A phased design-freeze schedule can allow the project to move while protecting critical interfaces. For example, early partition and MEP decisions may be locked while decorative accessories remain flexible.

Late aesthetic changes can have technical consequences.

Changing a ceiling feature may affect lighting and air distribution. Moving a counter may alter power and drainage. Revising joinery dimensions can change wall backing, sockets or equipment clearances.

The project should therefore assess late changes against construction progress, procurement status and affected disciplines before they are treated as simple design adjustments.

Plan the fit-out around opening readiness, not only construction completion.

Commercial spaces often need furniture, technology, specialist equipment, signage, stock, cleaning, staff training and final operational checks after the main contractor believes the physical works are substantially complete.

These activities should be part of the final programme. If they are left outside the construction plan, the client can meet the building completion date and still miss the business opening date.

Use room-by-room readiness near the end.

A room or zone can be treated as ready only when finishes, services, joinery, cleaning, furniture and outstanding snags are at the condition required for the next user or activity.

This approach makes final coordination more practical than one overall percentage. It shows which spaces can be handed over, furnished or commissioned and which still contain blockers that need focused action.

Common fit-out mistakes usually begin before construction.

Starting demolition before the new layout and services are sufficiently coordinated can create pressure to make irreversible decisions on site. Likewise, ordering finishes before final quantities and substrate conditions are understood can create waste or shortages.

Another frequent issue is treating joinery as a decorative package when it contains technical interfaces. Power, plumbing, lighting, ventilation, appliances and access panels can all be affected by custom built-in elements.

Do not leave procurement and furnishing outside the fit-out programme.

A space may be physically complete but unable to open because furniture, equipment, signage or technology has not arrived. These packages should share the same completion logic as the construction work.

Finally, avoid allowing repeated small design changes to move directly from conversation to site. Each may appear minor, but together they can create rework, material waste and inconsistent records. A simple change route keeps the final space coherent and the commercial impact visible.
