Building Estimating Services Across Southampton & Hampshire
Southampton’s construction sector is thriving, fuelled by the city’s ongoing waterfront regeneration, major port infrastructure investment, and growing demand for residential and student accommodation. From contemporary apartment developments overlooking the Solent to sensitive renovations of Victorian and Edwardian terraces in Portswood and Highfield, precise cost estimation is critical to project success on the South Coast.
Our qualified Quantity Surveyors have in-depth knowledge of the Southampton and Hampshire market. We apply South Coast labour rates, account for the coastal and marine ground conditions that affect waterfront builds, and understand the practical considerations of working in a busy port city where logistics and access can influence project costs.
Whether your project is in Southampton city centre, the Ocean Village marina district, or the wider Hampshire and New Forest area, our estimates reflect current local construction costs and regional market conditions.
