Decking Fitted in Swallownest

Swallownest sits in an unusual position. It has a Sheffield S26 postcode, most people here think of themselves as being on the edge of Sheffield, and yet for planning purposes Swallownest falls under Rotherham Metropolitan Borough Council rather than Sheffield City Council. That catches people out, and it is the first thing worth knowing if your deck is going to need permission.

The housing tells the area's story. Swallownest grew around the collieries, and the older terraced and semi‑detached stock reflects that — solid, modest gardens, often with rear access. Around it sit decades of later development: interwar and post‑war semis, and then the substantial modern estates that have gone up over recent years, with Waverley and the surrounding new build growing steadily on the old Orgreave site.

That mix matters because it changes what a deck needs to do. Newer estate gardens are usually flatter, smaller and more rectangular than an older Sheffield plot, frequently with a fitted lawn, a fenced boundary and not much depth. The right answer there is often a straightforward ground level platform running the width of the house — less groundwork, less cost, and it turns an unused strip of grass into the part of the garden you actually sit in.

Older gardens here tend to be longer with more established planting, and often suit a deck placed away from the house to catch afternoon sun rather than immediately outside the back door.

This is one of the few parts of our patch where we can say that honestly. Much of Sheffield is built on hills, and a large share of what we quote involves building a level platform over ground that falls away. Around Swallownest, Aston and Aughton, a good number of gardens are genuinely close to level.

That works in your favour on price. A ground level deck on firm, flat ground needs far less sub‑frame, no retaining, no steps and no balustrade, which takes a meaningful slice out of both labour and materials. It sits at the lower end of the range rather than the upper.

Two things still deserve attention. Newer estate gardens can drain poorly in their first years, because construction traffic compacts the ground and topsoil depth is often thin. Where a garden holds water we build in proper ventilation beneath the frame and would normally steer you towards composite rather than timber. And on a small plot, proportion matters more than it does on a large one — a deck that swallows the whole garden rarely looks right, and we would rather design something that leaves a bit of lawn.

Where a boundary needs replacing at the same time, we fit fencing and composite fencing too, so the deck and the fence go in together and line up properly.

As above, Swallownest comes under Rotherham Metropolitan Borough Council, not Sheffield. The national permitted development rules are the same either way, but if you need to check anything or make an application, Rotherham is who you speak to.

Decking is generally permitted development provided the platform sits no more than 300mm above existing ground level, and that it and other buildings cover no more than half the land around the original house. On the flatter estate gardens around here that threshold is comfortably met by most designs, which is one reason ground level decks are so common locally.

Where there is a drop of more than 600mm from the deck edge, guarding is required under Part K of the Building Regulations — relevant if you are building a raised deck on one of the older, longer plots.

One point specific to newer estates: some modern developments carry restrictive covenants or estate management rules covering what can be built in a garden, entirely separate from planning. Those sit in your deeds or with the management company. We build decks, we are not solicitors or planning officers — it is worth a look at your paperwork if your property is recent.
