Your Local Home Extension
Specialists in Sundridge
Buildaway extends properties throughout Sundridge and BR1, from Sundridge Park Station and Plaistow Lane to the family houses bordering Plaistow Lane, managing structure and consent as one package.
Many Sundridge properties sit close to Sundridge Park Conservation Area with tight controls on elevations, 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. For Sundridge owners near Sundridge Park Golf Club or Chinbrook Meadows, Buildaway covers the BR1 streets either side of Willoughby Lane on the same schedule.
Buildaway combines careful design with genuine workmanship on every Sundridge extension. From BR1 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 Sundridge, answered.
Do you handle drawings and building control?
Yes. Buildaway coordinates structural calculations, the building control application and inspections, and manages the party wall process where a neighbouring wall is affected, which is frequent on Sundridge semi-detached properties.
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 BR1, so Buildaway prices them properly rather than provisionally.
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 Sundridge 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.
Will an extension affect my neighbour?
On any semi-detached or terraced Sundridge property the Party Wall Act applies and notice must be served. Buildaway handles the notices and statutory periods, and factors them into the start date rather than discovering them mid-project.
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 Sundridge work so the opening-up happens over the shortest practical period.
