One of the questions we’re often asked about construction projects is how quickly work can begin. And while everyone wants to see progress, there’s quite a bit to organise before the first spade goes into the ground.
Planning permission: Depending on the size, position and type of extension, you may need planning permission. Some domestic extensions can be built under permitted development rights, but these come with specific conditions and limitations.
Building Regulations: Even when planning permission isn’t required, your project will usually still need to comply with Building Regulations covering matters such as structure, insulation, fire safety and drainage.
Structural calculations: If the project involves removing load-bearing walls, creating large openings or installing structural steelwork, a structural engineer will usually need to provide the necessary designs and calculations.
Party Wall matters: If you’re building close to a neighbouring property or carrying out certain work to a shared wall, the Party Wall Act may apply. This needs to be considered before work begins.
Access and site preparation: How will materials get onto the site? Is there room for a skip? Will scaffolding be needed? Are there underground services or existing drainage runs to work around?
And finally, a realistic programme of work: Construction involves different trades, material deliveries, inspections and sometimes the British weather. Planning the sequence properly helps keep everyone informed and reduces unnecessary delays.
At 2 Counties Construction, we work with clients from the early planning and design stages right through to completion, helping make the whole process as straightforward as possible.
