About Amenity Space Requirement Calculator

Amenity space for community halls, creches, clubhouses and similar facilities is set as an area per head of design population. Comparing the provision per person against the standard is the check planning authorities apply, and it is population rather than site area that drives the requirement.

Formula

Amenity requirement

Required = design population x area per person; provision per person = provided / population

Worked example

With the default values below, Amenity Space Requirement Calculator returns Amenity space required of 1,800.0. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Preliminary estimate only. Amenity space standards and design population factors are set by local development control regulations.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Amenity Space Requirement figure worked out?

Required = design population x area per person; provision per person = provided / population. Amenity space for community halls, creches, clubhouses and similar facilities is set as an area per head of design population.

How is design population determined?

Usually as dwelling units times an assumed household size, or from a per-unit occupancy factor set in the regulations. It is not the developer's marketing estimate.

What values do I need to enter?

This calculator takes 3 inputs: Design population, Amenity space per person, Amenity space provided. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
