Whether you’re expanding your family home, renovating a period property, or planning a new build, construction projects in Hertfordshire require expertise, precision, and careful planning. 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.

2. 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.

3. 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.

4. Windows, Doors, and Roofing

Energy efficiency and design elegance go hand in hand:

• Triple-glazed windows for optimal thermal performance
• Stylish, durable doors that complement your home
• Modern roofing systems for protection and aesthetic appeal

These elements enhance comfort, reduce energy bills, and future-proof your home

5. Interior Works

Interior finishes transform a house into a home. Our certified tradesmen handle:

• Plumbing and electrical systems
• Carpentry, flooring, and plastering
• Painting, decoration, and fine finishes

Every interior feature is completed with precision to maximise comfort and functionality.

6. Final Inspections and Handover

Before handing over your home, our project manager conducts a thorough walkthrough, verifying:

• Quality of workmanship
• Compliance with safety and building standards
• Design accuracy and finishing details

This ensures complete satisfaction and a smooth transition into your newly expanded or renovated home.
