New Build Construction Swansea

Site Preparation and Planning

Every successful new build begins with thorough site assessment and careful planning. Our team works closely with clients, architects, structural engineers, and planning consultants to develop practical, cost-effective build strategies that meet project objectives and comply with all relevant regulations.

By involving our construction specialists early in the process, we identify opportunities to improve buildability, reduce costs, and address potential ground or access issues before they affect the programme.

Groundworks and Foundations

Managing site excavation, drainage, service trenches, and foundation construction requires careful sequencing and the right team on the ground. Our in-house groundworks capability means we control this critical stage directly, without relying on subcontractors for work that sets the standard for everything above it.

We build strip, trench fill, raft, and pad foundations to structural engineer drawings and work to BC2, BC3, or bespoke engineering specifications depending on soil conditions and structural load requirements. If you do not yet have a structural engineer, we can connect you with a trusted local practice.

ICF and Structural Construction

As registered NUDURA ICF installers, we build new homes and commercial structures using Insulated Concrete Formwork. ICF delivers superior thermal performance, a structurally resilient wall system, and faster build programmes compared to traditional cavity masonry, making it increasingly the preferred choice for clients building in South Wales.

Beyond ICF, our structural capability covers wall construction, steel frame installation, floor cassettes, roof structure, and building envelope work. We keep the programme tight and the sequencing logical so follow-on trades are never left waiting.
