1. Define your housing wishes
Explain what should work better in daily life. Collect photographs, existing plans and rough garden dimensions. Make an initial design and note your essentials and uncertainties.
2. Assess the property
A survey looks beyond the rear wall. Ground conditions, access, structure, services and drainage affect the work. Missing information may require additional investigation.
3. Develop the design and quotation
The design translates wishes into dimensions, materials and connections. The quotation describes the work, finishes and responsibilities. Check what is included before agreeing.
4. Prepare and produce
Required checks, permits and scheduling must align. After final choices, the prefab components are prepared and the site requirements for installation are confirmed.
5. Foundations, installation and connections
Groundworks and foundations follow the detailed plan. Prefab components are delivered and installed, followed by the house connection, waterproofing, services and finishes. Quick installation is only one stage of the full process.
6. A careful handover together
Check the work against the agreement at handover. Record outstanding items and follow-up arrangements. Keep maintenance information, relevant warranties and drawings.
From the first conversation to decision points
A useful programme identifies decisions and dependencies. The intended use, dimensions and budget must first fit together. Existing conditions and detailed design follow. Production, delivery and site work should use the same final documents. Agree on a single contact and how changes are recorded so amendments do not appear in one document but disappear from another.
Preparing for work at your home
Agree which rooms remain accessible, when services may be temporarily unavailable and how the house will be protected from dust and weather. Discuss working hours, material storage and access to the site. Include pets, children and neighbours in the planning. A short practical overview with a contact person, weekly schedule and access arrangements makes the work clearer for everyone.
Handover with a clear record
Inspect the extension together and compare the result with the agreed work. Record outstanding items, who will resolve them and when. Check window and door operation, finished junctions and the agreed services. Ask which documents you will receive and where to direct maintenance questions. Keep the handover list with the drawings and quote.
Who decides when?
Assign one decision-maker and one current drawing to each phase. Record materials, service positions and changes on the same document, and check that the quotation matches before production. Agree access, working hours, keys and any water or power shutoffs. Brief regular discussions help resolve questions before they cause delays.
