Your Local Home Extension
Specialists in Tooting
Buildaway builds extensions across Tooting and the SW17 area, working on the Victorian bay-fronted terraces, ideal for side-return extensions and rear infill along Mitcham Road and Upper Tooting Road, and on the larger plots running toward Tooting Bec Lido. Tooting Broadway and Tooting Common are familiar territory.
Many Tooting properties sit close to Heaver Estate, where proportionate additions are assessed against the original dwelling rather than its current size. Buildaway will say at survey stage whether a scheme is likely to succeed before you spend money on drawings. Recent extension projects in Tooting have taken in Mitcham Road, Trinity Road and the streets around Tooting Market, all within the SW17 coverage area.
Buildaway combines careful design with genuine workmanship on every Tooting extension. From SW17 terraces to detached family homes, we deliver additions that feel part of the original house, backed by clear communication throughout the build.

Frequently Asked Questions
Your questions about home extensions in Tooting, answered.
What usually drives the cost up?
Groundworks and glazing. Poor ground conditions mean deeper foundations, and large glazed openings need steel. Both are established at survey in SW17, so Buildaway prices them properly rather than provisionally.
Can I stay in the house during the build?
Usually yes for a single-storey rear extension, since the existing structure stays sealed until late in the programme. Buildaway phases the Tooting work so the opening-up happens over the shortest practical period.
Do I need planning permission for an extension in Tooting?
Many single-storey rear extensions fall under permitted development, but that changes inside Heaver Estate and Tooting Broadway conservation areas, with Article 4 direction on some terraces, where allowances are materially tighter. Buildaway establishes which category your SW17 property falls into before drawing anything.
What is a build-over agreement and will I need one?
If the extension crosses a public sewer you need written consent from the water authority before building over it. It is common in Tooting because of how rear drainage runs. The application takes several weeks, so Buildaway starts it at design stage rather than letting it delay the build.
How long does a rear extension take to build?
A single-storey rear extension is generally ten to fourteen weeks on site once foundations start, depending on glazing lead times. Double-storey work runs longer. Buildaway separates the design and consent period from the build period on the programme so expectations are realistic.
