BUILDING COSTS

The Association is frequently asked to provide information on building costs. There is a common but erroneous belief that building costs can be calculated according to a rate per sqm.

In order to achieve a reasonably accurate construction cost estimate, detailed and accurate information is required. The following are examples of information needed to estimate building costs.

Finishes Specifications

It stands to reason that the cost of constructing a standard garage or pool-shed will be far lower than for an “upmarket” house with expensive carpets, windows, fittings etc.

Wall to Floor Ratio

The shape of a building affects the cost. For example the total wall area required for a square building will be less than that for a rectangular one but still provide the same floor area.

Floor to Ceiling Height

A Building with a greater floor to ceiling height will obviously cost more as additional wall area is required to enclose the floor area.

Plumbing and Electrical Installations

The amount of plumbing installations such as toilets, bathrooms etc. can significantly change the total cost of a building. This also applies to electrical installations e.g. air-conditioners, automatic gates and geysers.

Internal Walls

The number of internal walls and partitions will have an affect on the overall cost of a building.

Region

Construction costs vary between different regions in South Africa.

General

Paving, swimming pools, tennis courts etc. also affect building costs.
