Your Local Home Extension
Specialists in Hayes
Many Hayes properties sit close to Hayes Village Conservation Area, 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. Hayes sits within Buildaway's established BR2 area, with extension projects completed around Hayes Village, Hayes Common and Hayes Street.
Across Hayes and BR2, Buildaway designs and builds extensions on 1930s detached and substantial semis, with period cottages around the village centre. Regular streets include Station Approach, Pickhurst Lane and Bourne Way, with Hayes Station and Hayes Street Farm inside the area.
With a strong reputation for quality workmanship, Buildaway delivers extension design and construction across Hayes and the wider BR2 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 Hayes, answered.
Will an extension affect my neighbour?
On any semi-detached or terraced Hayes 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 you extend within Hayes Village Conservation Area?
Sometimes, but the tests are stricter and additions are assessed against the original dwelling rather than its current size. Buildaway will tell you honestly at survey stage whether a scheme is likely to succeed before you spend money on drawings.
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 BR2, 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 Hayes work so the opening-up happens over the shortest practical period.
Do I need planning permission for an extension in Hayes?
Many single-storey rear extensions fall under permitted development, but that changes inside Hayes Village Conservation Area and Hayes Common protected open space, where allowances are materially tighter. Buildaway establishes which category your BR2 property falls into before drawing anything.
