This is because the capital is classed as a high-risk location for overheating, so compliance demands more rigorous design solutions. For architects, that can feel restrictive — but with the right approach, it doesn’t have to be.

At Southmore Court - an aged living scheme in Bromley, we helped architects Designscape to achieve compliance with Part O.

We carried out energy modelling and carbon assessments to compare decentralised, renewable and low-carbon energy options to achieve compliance for the London Borough of Bromley.

The outcome – a 58% reduction in total carbon emissions compared to Building Regulations Part L and fully aligned with the London Plan.

Part O compliance is particularly demanding in London due to the higher risk of overheating. We recommended dynamic solar shading to limit solar gain and mitigate overheating.

Designscape adopted this passive solution and incorporated projecting fins in a box-style configuration into the design for the windows on the upper floors.

Their solution was to add projecting fins in a box-style configuration to the windows on the upper floors. This will reduce solar gain in all angles of sun, whilst maintaining design integrity.

The result? Comfortable, future-proofed accommodation for the care home residents that meets the more stringent requirements of the London Plan.

Part O isn’t about limiting design. With the right team, collaboration and a practical approach, it is an opportunity to deliver buildings that perform better for occupants all year round.

The result is a building which meets the rigorous standards of the London Plan and will enhance occupant comfort and wellbeing.
