A commercial building has to satisfy two clients: the developer who commissions it and the tenants who will occupy it. Decisions that suit the first and inconvenience the second tend to surface as leasing problems later.
Parking and access shape the plan
Required parking provision influences the footprint, the basement extent and sometimes the massing itself. Because it is a planning requirement rather than a preference, it is worth confirming before the architectural concept is developed rather than after.
Façade performance in a hot climate
Glazing ratio, shading and insulation determine how hard the cooling system has to work for the life of the building. A façade chosen for appearance alone transfers its cost to the mechanical design and then to the operator, every year.
Shell and core, then fit-out
Leaving sensible capacity and routing in the base build makes tenant fit-out faster and cheaper. Riser space, spare electrical capacity and accessible ceiling voids cost little at construction stage and are expensive to create afterwards.
It is also worth agreeing where each tenancy stops and the base build starts, in writing, before the first lease is signed. Most fit-out disputes are boundary disputes.
Vertical circulation
Lift provision follows the population the building is expected to carry, not the number of floors alone. Under-providing shows up as waiting times that tenants notice daily, and adding a lift later means taking floor area on every level.
The position of the core matters commercially as well: it determines how much of each floor plate is lettable and how easily a floor can be split between two tenants.
