The average home is not on a perfect, flat piece of land. Therefore, unique spaces require something other than the standard ‘box on the back extension’. Such sites might have to deal with sloping gardens, raised ground levels and basements or strange changes in level.
What is a split-level extension?
A split-level design incorporates two (or more) floor heights into the new space. The first extension is not forced to align everything with the existing house, but rather steps up or down following the site.

When split-level works brilliantly:
Properties situated on hills with a garden that slopes away
Floors built above natural ground or suspended (sometimes seen with older homes)
Lower ground or basement levels in the back
The benefits of a split-level approach:
Less excavation or retention work
To help keep lower into the extension neighbours’ side
Have natural areas (kitchen/dining, snug, play area) without too many walls
Introduce some character with different features such as steps, built-in seating and varying ceiling heights.
Common mistakes to avoid:
Small level changes that happen too much (fussy feeling)
Step position, poor lighting
Not anticipating future requirements.
A practical next step:
This is where you want to invest in getting accurate levels surveyed before committing to drawings, and consider how you’re going to get around day-to-day.
A split-level extension can make a challenging plot feel purpose-built rather than constrained.
