Landscaping in Bromley

The largest borough,
and the largest gardens.

Bromley is the biggest London borough by area, and it shows in the plots. This is where full garden design — structure, levels, planting and buildings together — genuinely pays off.

Building in Bromley

What we work with here

01

Substantial suburban plots, and green belt beyond

Bromley, Beckenham, Chislehurst, Petts Wood and West Wickham are largely inter-war and post-war suburbia built at low density, with detached and semi-detached houses on deep plots — rear gardens well over a hundred square metres are routine and considerably larger is common. Chislehurst and parts of Orpington add older, larger houses on grounds that read as small landscapes. Beyond the built-up area the borough runs into green belt and open countryside. Nearly everything has side access and a frontage that takes a car, so machinery reaches the back and the full range of work is practical.

02

Clay in the north, chalk towards the Downs

The geology shifts across the borough. London Clay covers the northern parts, while the ground rising south towards the North Downs is chalk — free draining, stable under load and much less prone to the seasonal shrink and swell that moves paving laid on clay. Chalk does soften if an excavation is left open in the wet, so the dig is protected properly. The practical point is that a single standard sub-base detail does not suit the whole borough, which is why the specification follows what the trial dig actually shows.

03

Space for a real design, and the rules that apply

A plot this size rewards planning rather than accumulation. The common failure is a large garden that has acquired a patio, a shed, a trampoline and a border over twenty years without any of it relating to the rest. A designed scheme resolves levels and drainage first, then establishes structure — terraces, routes, hedging, a garden building — and plants into that framework. Outbuildings are usually permitted development within the height and coverage limits, front driveways need no permission if permeable or draining within the boundary, and mature trees may carry Tree Preservation Orders.

Questions we get asked

Bromley, specifically

What does a full garden design involve on a large Bromley plot?
A survey of the existing levels, trees and drainage; a layout that establishes the spaces and how you move between them; a materials and planting specification; and a build sequence that puts drainage and levels in before anything visible. On a plot this size it is frequently built in phases to spread cost. The point of designing first is that on a large garden, decisions made piecemeal rarely add up to anything coherent.
Do I need planning permission for a garden room in Bromley?
Usually not, if it stays within permitted development. A single-storey outbuilding for domestic use generally qualifies where it is not forward of the principal elevation, meets the height limits — which are lower within two metres of a boundary — and, with all other buildings, does not cover more than half the land around the original house. Green belt land and previous extensions can change the position, so we check the specific property.
Does the ground really differ across the borough?
Yes. The northern parts sit on London Clay, which shrinks and swells with the seasons, while the higher ground running south towards the North Downs is chalk, which drains freely and is far more stable under load but softens if left open in wet weather. They call for different sub-base depths and different drainage strategies, which is why we dig a trial hole before specifying rather than applying one detail borough-wide.
