At ACR Build, we specialise in residential extensions, renovations, and new builds, delivering high-quality craftsmanship and exceptional results across Harpenden, St Albans, and beyond.

From groundwork to finishing touches, we manage every detail to ensure your home is structurally sound, visually appealing, and energy efficient.

  1. Site Preparation and Groundwork

Construction begins with meticulous site preparation. This stage includes:

  • Securing planning permission and approvals
  • Reinforcing and stabilising foundations
  • Adjusting drainage and landscaping
  • Ensuring safe access for workers and machinery

Proper groundwork ensures long-term stability and minimises potential construction delays, forming the backbone of every successful project.

  1. Structural Build

The structural phase creates the framework of your home. Our experienced builders use premium materials and advanced techniques to ensure durability:

  • Installation of structural steel beams
  • Construction of load-bearing walls
  • Accurate alignment and balancing for safety

Every structural decision is guided by engineers to guarantee resilience, whether for a double-storey extension or a complete new build.

  1. External Build

Once the structure is secure, external works begin. Walls, insulation, and roofing are constructed with precision, maintaining:

  • Seamless integration with existing architecture
  • Superior insulation and weatherproofing
  • Aesthetic harmony between old and new structures

Our team ensures your property’s exterior is both functional and visually cohesive.
