Assistant Site Manager

Assistant Site Manager Opportunity

West Sussex
Start: December 26 / January 27

Join one of the UK’s leading housebuilders as an Assistant Site Manager on a brand-new, 100-unit timber frame development in West Sussex. With a December / January start, this is an opportunity to get involved at the beginning of a residential scheme and contribute as it takes shape. For someone looking to develop their site management experience in housebuilding, the role offers a practical focus: helping turn construction plans into well-built homes through careful coordination, consistent standards and attention to detail.

Role Purpose

The Assistant Site Manager will support the day-to-day running of the development, helping coordinate trades, monitor progress and maintain safe, orderly working areas. The role combines a visible presence on site with the planning and follow-through needed to keep work moving. On a timber frame scheme, particular attention will go towards sequencing activities, checking readiness for follow-on trades and identifying issues early. The aim is to support reliable delivery while protecting workmanship, site safety and the quality of completed homes.

Key Responsibilities

• Support the planning and coordination of daily construction activities across the development.
• Help organise subcontractors and trades so work progresses in the agreed sequence.
• Monitor progress against site programmes and flag delays or constraints promptly.
• Assist with coordinating timber frame activities and the transition to follow-on trades.
• Carry out regular checks on workmanship and raise defects for timely resolution.
• Promote safe working practices and help monitor compliance with site procedures.
• Check that materials, access and work areas are ready for upcoming activities.
• Maintain accurate site records, including progress updates and outstanding actions.
• Support snagging, finishing and preparation of homes for inspection and handover.
• Communicate clearly with site colleagues, subcontractors and suppliers to resolve day-to-day issues.

Requirements

• Relevant residential construction experience would provide a strong foundation, whether gained in assistant site management, site supervision or a trade-based role.
• Familiarity with timber frame construction would be useful, alongside an understanding of how different trades and construction stages fit together.
• Practical awareness of site health and safety, quality checks and the importance of addressing concerns promptly.
• An organised approach to coordinating work, tracking actions and recognising issues that could affect progress.
• Clear communication skills and the confidence to work constructively with trades, subcontractors and site colleagues.
