More space in your existing home
Home extensions add space while retaining the home and location you already have. Compare builders with explicit extension experience, then clarify the design, existing conditions and scope before seeking a dependable price.
An extra bedroom, larger living space, additional storey or connected wing can create very different design and construction requirements. Begin with the rooms and daily use you need. Ask a designer and suitable builder to compare feasible options for the property before committing to a layout.
An extension joins new foundations, structure, roofing and services to an existing building. Ask which records and investigations are needed, what is known about those interfaces and what remains uncertain. Ground conditions, access, drainage and the condition of retained materials can influence the scope.
Confirm who owns design coordination, engineering, approvals and the written scope. Compare builders using the same information and ask for explicit inclusions, exclusions, allowances and a documented variation process. An early planning range is not a fixed quote.
Discuss temporary weather protection, secure access, dust, noise and when services or rooms will be unavailable. Whether you can remain at home depends on the proposed sequence and safety arrangements. Ask for a programme that makes those decisions visible before work starts.
