This project involved the construction of a high-quality double storey extension to a detached home in Ayot St Lawrence, Hertfordshire.


The extension was designed to increase living space while maintaining the character and proportions of the existing property.

Client Brief:

Client Brief

The homeowners wanted to expand their living space and improve the flow between formal and informal areas. The project included an additional bedroom, a larger bathroom, and an extended entrance with cloakroom and W/C.


Project Details

  • Location: Ayot St Lawrence, Hertfordshire
  • Project Type: Double storey residential extension
  • Services Provided: Full build, structural coordination, finishes
  • Duration: 6 months
  • Approx. Budget: £175,000

The Brief & Challenges

The property sits within a sensitive village setting with adjacent homes and mature landscaping. The design needed to complement the existing architectural features and respect local planning guidelines.

Key considerations included:

  • Maintaining proportion with the original house
     
  • Managing site access and neighbour disruption
     
  • Coordination of structural steel supports for the extended footprint
     

Despite these constraints, we delivered a cohesive and aesthetically balanced extension that resolves both spatial and functional requirements.

Our Approach & Solution

Our structured approach ensured clarity from initial consultation through to completion:


  • Initial assessment & planning – site survey and build strategy aligned with the client’s goals
  • Design coordination – working with the architect to integrate the extension seamlessly
  • Construction management – carefully sequenced works to minimise disruption
  • Quality control – high standards maintained across all finishes and detailing

Construction Phase Highlights

During the build, we focused on:

  • Robust structural sequencing to support additional load without affecting existing spaces
     
  • Protecting and preserving adjacent finished areas during internal works
     
  • Maintaining safe, clean site conditions throughout construction
     

Intermediate milestones were reached on schedule, and programme management ensured alignment with client expectations.

Completed Outcome

The completed double storey extension delivers:

  • Increased functional living space tailored to modern family use
     
  • Thoughtfully integrated architectural detailing
     
  • Improved light and circulation
     
  • A high-quality finish throughout
     

This project demonstrates our capability to manage complex house extensions with professionalism and precision, meeting both aesthetic and practical goals.

Client testimonial

We are extremely pleased with the work carried out on our extension. From the start, the team demonstrated professionalism, attention to detail, and a clear understanding of our requirements.


The quality of workmanship has been excellent, and communication throughout the project was consistent and reassuring. The project was completed on time, and the final result exceeded our expectations.
