Landscaping in Harrow

Metroland gardens,
brought up to date.

Harrow is the Metroland heartland: mile after mile of 1930s semis built for gardens. Most are now due their second or third rebuild, and the bones are worth working with.

Building in Harrow

What we work with here

01

The 1930s semi, in quantity

When the Metropolitan Railway pushed out to Pinner, Rayners Lane and Stanmore, the housing that followed was remarkably consistent: bay-fronted semi-detached houses, a front garden deep enough for a car, a side passage, and a rectangular rear garden of decent size. That consistency is useful. The layout problems repeat, so do the opportunities — and the side access almost every one of these houses has means we can get a mini digger to the back, which changes what is economic to build. Harrow on the Hill and parts of Stanmore add older and larger houses with more varied plots.

02

Clay ground and tired original surfaces

The ground is London Clay, with gravel patches on the higher ground. Most of what we replace in Harrow is not a failed modern installation but an original or first-replacement concrete path and crazy-paving terrace laid decades ago, directly onto the soil, with no sub-base and no falls. It has usually sunk towards the house, which is exactly the wrong direction. Rebuilding properly means taking it all out, excavating to a firm formation, and laying a compacted sub-base with the fall running away from the building — unglamorous work that determines whether the new surface lasts thirty years or three.

03

Front gardens, parking and permeable surfaces

Driveway work is a large part of what we do in Harrow, because the frontages were built for it. The national rule applies: no planning permission is needed for a front driveway if the surface is permeable, or if water from a sealed surface drains to a border or soakaway within your own boundary; permission is needed for more than five square metres of impermeable surface draining to the road. Permeable block paving and resin-bound gravel over a properly built porous sub-base both satisfy this and, on these generous frontages, there is room to do it without compromise.

Questions we get asked

Harrow, specifically

Our 1930s crazy paving has sunk towards the house. Can it be relaid?
The surface can be replaced, but relaying the same slabs on the same ground would repeat the failure. Paving of that age was typically bedded straight onto soil with no sub-base and no fall, so it settles unevenly and ends up running water back at the wall. The fix is to excavate, build a compacted sub-base to a firm formation, and lay new paving to a deliberate fall away from the house with drainage at the threshold.
Which permeable driveway surface is best — block paving or resin?
Both work; they fail differently. Permeable block paving is exceptionally durable, individual blocks can be lifted and replaced if a service needs digging up, and it copes well with turning wheels. Resin-bound gravel gives a smoother, quieter, seamless finish that suits period frontages and is easier to keep clear of weeds. The deciding factor is usually the sub-base, which has to be genuinely porous for either to be permeable in law as well as in name.
Can you get a digger into a Harrow back garden?
Usually, yes — the side passage on a typical Metroland semi will take a micro or mini digger, and that makes a real difference. Machine excavation means we can dig to a proper formation depth and get the arisings out quickly, rather than barrowing everything by hand through the house. It is one of the reasons a comparable garden costs less to build well here than in an inner-London terrace.
