    How your project works

    Six clear stages, from first enquiry to completion — whether we design and build, or build from your drawings.

    For clients who need the whole project managed: design, planning, building regulations and construction, from initial enquiry through to completion.

    1. Step 1: Initial Consultation & Feasibility

      Timeline: 1–3 days

      Initial consultation to discuss requirements, ideas and budget.

    2. Step 2: Architectural Design & Drawings

      Timeline: 1–4 weeks

      Architectural drawings and proposed layouts.

    3. Step 3: Planning Permission

      Timeline: 6–12 weeks (estimated)

      Planning application preparation and submission.

    4. Step 4: Structural Engineering & Building Regulations

      Timeline: 1–3 weeks, depending on complexity

      Structural calculations and drawings.

    5. Step 5: Contract & Building Works

      Timeline: Typically 4–20+ weeks, depending on project type

      Begin construction and manage all building works.

    6. Step 6: Completion & Handover

      Final client walkthrough and handover.

    All timelines are indicative. Your project-specific schedule is confirmed before construction.

    LINX Glass · Our glazing division

    The glass that makes a LINX extension.

    Glazing, bi-folds, roof lights and structural glass — the openings that define a LINX extension, from the group's glazing division, LINX Glass.

    Working inside the LINX group means glazing can be drawn into an extension at the design stage, with the openings, steels and roof lights planned together. It is just as available on its own — a new set of doors, a roof lantern or an acoustic upgrade.

    • FENSA-certified fitters
    • A+ energy-rated glazing
    • 10–25 year manufacturer guarantees
    • FENSA, TrustMark and FMB accredited
