Fixed-fee architectural drawings for loft conversions across Andover and the surrounding Test Valley villages — all managed by Hampshire Build.
Andover's residential estates — built predominantly in the 1960s through 1980s — contain some of Hampshire's best opportunities for loft conversion. Many detached and semi-detached properties have generous roof pitches and hipped roofs well suited to hip-to-gable conversions that dramatically increase usable floor space. Hampshire Build produces all the drawings and manages the planning process. You choose the builder.
Planning Approval Rate
Andover grew substantially from the 1960s onwards as part of the London overspill programme, creating large residential estates with a predominantly consistent housing type. Areas such as Millway Rise, Walworth, Hatherden, Charlton, and the northern estates contain hundreds of three-bedroom detached and semi-detached houses built with generous pitched roofs — many of them hipped on all sides.
These properties represent an outstanding opportunity for loft conversion. A hip-to-gable conversion on an Andover detached house can add 20–30m² of usable floor space that simply does not exist with a standard dormer. The resulting loft room — typically a large double bedroom with en-suite shower room, or a spacious home office — transforms the property without requiring planning permission in most cases when combined with a rear dormer within Permitted Development limits.
Test Valley Borough Council administers planning applications for Andover and the surrounding villages. The council's planning officers apply the same national Permitted Development framework as other Hampshire authorities, but with local plan policies that occasionally affect proposals in the older market town area and the surrounding conservation villages. Hampshire Build's familiarity with Test Valley's requirements means our applications are well-prepared and consistently approved.
For homeowners in the villages north and west of Andover — Whitchurch, Hurstbourne Tarrant, St Mary Bourne, and Longparish — we provide the same fixed-fee service, with appropriate consideration of the rural setting and any village character policies that apply to your specific property.
