Survey Before House Extension Harrow
Harrow homeowners extending their properties need accurate surveys. Measured building surveys capture the existing house. Topographical surveys capture site levels. Combined surveys provide comprehensive data in one fixed-fee commission.
Why Harrow Homeowners Need Surveys
Harrow planning applications require accurate existing drawings. Extensions are designed against existing conditions. Structural works need foundation information. Drainage connections need levels.
Harrow has varied property types. Detached houses in Harrow on the Hill. Semi-detached in Roxeth. Terraces in South Harrow. Each type needs appropriate surveying.
Without accurate surveys, extensions are designed against guesswork. Guesswork causes errors. Errors discovered during construction are expensive.
Harrow Property Types
Harrow includes diverse property types:
Harrow on the Hill: Large detached Edwardian and Victorian houses. Measured surveys capture complex geometries and period features.
Roxeth and North Harrow: Semi-detached houses with generous gardens. Topographical surveys capture garden levels and drainage.
South Harrow and Rayners Lane: Edwardian and Victorian terraces. Measured surveys for period properties.
Stanmore and Belmont: Mix of period and contemporary properties. Surveys for all property types.
Harrow surveyor access via Metropolitan line and bus routes. Survey scheduling confirmed at quotation.
Harrow Planning Applications
Harrow planning applications require existing drawings and site levels. Measured surveys provide floor plans, elevations, and sections. Topographical surveys provide site plans with contours and spot levels.

Loft conversions: Roof survey needed. Headroom measurements and roof structure captured.
Side extensions: Boundary considerations. Survey of existing house and adjacent boundaries.

Different Harrow properties need different surveys:
Detached houses: Full measured survey of all floors. Topographical survey of larger plots.

Why Combined Surveys for Harrow Extensions
Combined surveys are more efficient than commissioning separately:
One site visit: Both measured and topographical surveys completed in fewer visits.
One invoice: Both surveys under one fixed-fee package.
Consistent data: Same coordinate system and datum for both surveys.
Better value: Combined surveys cost less than commissioning separately.
