Planning and building regulation drawings in Tooting (SW17)
Ask two homeowners in SW17 what it takes to get an extension approved and you can get two very different answers, and both can be right. Most of the postcode is Edwardian terrace, built to a pattern that repeats along Tooting High Street, Mitcham Road and Longley Road, and Wandsworth has seen that pattern so often that a well-drawn rear extension or loft conversion moves through the system without surprises. Tucked into that same postcode, though, sits the Totterdown Fields estate, the low-density cottage housing the London County Council built from 1903 as its first estate of this kind anywhere in the capital. It looks unassuming from the street, but the council treats it as a heritage asset, and that changes the entire brief.

We treat the two contexts as separate jobs from the moment a client calls. On the ordinary terraced streets, a side-return or a loft dormer is often a matter of confirming permitted development rights and producing accurate drawings that match what Wandsworth expects to see. On Totterdown Fields, the starting question is different: what would the estate's original architects have done, and how far can a modern extension go before it stops reading as part of that pattern. Roof pitches, window proportions and boundary treatments were designed as a set here, not chosen house by house, so a change that looks trivial on Mitcham Road can be the whole application on the estate. Garden depths on parts of the estate are smaller than on the surrounding terraces too, which puts a practical ceiling on how far back a rear extension can reasonably go before it eats the outdoor space that made the estate work in the first place. Knowing which street a client is on, before a single line is drawn, is most of the job.
Planning in Tooting: what to know before you apply
Wandsworth deals with Tooting through two lenses. Away from Totterdown Fields, the borough's terraced-housing expectations apply much as they do across its other Victorian and Edwardian streets between the commons: side-returns and rear extensions are common enough that the council assesses them against a settled pattern, and drawings that match that pattern tend to move through validation cleanly. Totterdown Fields sits under its own conservation area and Article 4 direction, which strips out permitted development rights for anything visible from the street: windows, doors, roofing, porches, hard surfacing, boundary walls and fencing, and demolition all need full planning permission rather than a permitted development check. That means more drawings, more detail on materials, and a design that answers directly to the estate's original character rather than to a generic terrace standard. We confirm which side of that line a property sits on before quoting or designing.
