The human version (we wrote this, not the council)
This section explains the evidence behind the housing size mix policy. The Strategic Housing Market Assessment 2026 recommended different size mixes for market housing, rented affordable housing and affordable home ownership, and these are reflected in the policy. Rented affordable homes are allocated by need under bedroom entitlement rules, so bedrooms should be doubles or twins wherever possible. Because buyers often choose larger homes than they need, 1-bed affordable ownership homes can be hard to sell, so the policy allows up to 10% rather than setting a fixed figure.

Policy HO.1
Housing Size Mix
The preferred size mix for affordable and market homes is set out below. The final mix
achieved on any site will be informed by the latest available evidence taking into
account any relevant and evidenced site-specific issues and local market
circumstances.

3 Bed 5 or 6 Person 25-30% 40-50% 40-45%
4 Bed+ 7 or 8 Person 5-10% 10% or less 20-25%
The person capacities set out above relate are mandatory for affordable homes and
recommended for market homes.
Policy HO.1 ~ Development Management Considerations
The use of a percentage range for each house size rather than a fixed percentage
allows a degree of flexibility to address site specific issues and where application of
the percentages results in a fraction of a dwelling. Applicants are recommended to
use the midpoint of the percentage range figures as a starting point when designing a
development.
Policy Justification
5.1.2 The Strategic Housing Market Assessment 2026 (SHMA) assessed the need for
different sizes of homes, with recommendations given separately for market housing,
rented affordable housing and affordable home ownership housing. These
recommendations are reflected in the policy.
5.1.3 Rented affordable housing is allocated to households based on need in
accordance with the bedroom entitlement rules. These rules expect certain groups to
share bedrooms rather than have their own rooms, including couples and two children
of the same gender under the age of 16. As such it is important to ensure the bedrooms
in affordable homes are doubles/twins wherever possible and as a minimum, in line
with the person capacities stated in the policy.
5.1.4 Affordable home ownership housing is not subject to the same rules however to
ensure homes remain desirable to Registered Providers (RP’s) who will buy the units
from developers and to allow for flexibility for changes in tenure if required, the person
capacities are extended to cover all affordable tenures.
5.1.5 In respect of the size mix for affordable home ownership units, unlike for rented
affordable homes, households are able to choose the size of home that suits their
requirements and preferences, subject to passing affordability checks. For this reason,
Registered Providers can find it difficult to sell 1-bedroom Affordable Home Ownership
dwellings as many households choose to buy a larger home than they need. To allow
flexibility around 1-bedroom Intermediate Homes the policy requirement allows ‘up to
10%’ as it is accepted that for some sites it may not be practical to include 1 bed units,
whilst on others, especially in town centre
