Specialists in Theydon Bois
Buildaway treats Theydon Bois extensions as a sequence: survey, drainage and consent, then structure, then finishes. Party wall notice is required on any semi-detached property here, and the notice periods are handled as part of the contract rather than left to you. Buildaway's CM16 work runs from Theydon Bois village green across to The Theydon Oak, taking in the properties along Forest Drive and Loughton Lane.
Extension work in Theydon Bois spans CM16 for Buildaway, covering Epping Forest, the properties off Piercing Hill, and the houses backing onto The Theydon Oak.
With a strong reputation for quality workmanship, Buildaway delivers extension design and construction across Theydon Bois and the wider CM16 area. Whether adding a single-storey rear extension or a double-storey addition, we explain the build cost and programme clearly and deliver structurally sound, well-finished results.

Frequently Asked Questions
Your questions about home extensions in Theydon Bois, 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 Theydon Bois 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 CM16, 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 Theydon Bois 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 Theydon Bois 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 Theydon Bois work so the opening-up happens over the shortest practical period.
