It then became common practice for developers to purchase the materials for the fit out of tenant areas, but not to install them, leaving them stacked on the open area floors.
However, the actual tenant's ideas often differed from the developer’s notional layouts and so money was wasted taking down ceilings and taking up floors, while mechanical and electrical services had to be altered to accommodate partition layouts. American developers initially fitted out offices, installing access floors, carpet tiles, ceilings, air conditioning and lighting on the basis of a notional layout for prospective tenants. The concept originated in the USA where it was applied to office buildings built by developers for rent. A range of other construction and fit out works are left to be completed before the building is occupied. The concept of shell and core (or base build) is that the developer's scope of works is the design and construction of the base building. 5 Related articles on Designing Buildings.3 Normal shell and core provision for a high-spec city office.
