Defford-Cum-Besford School

Project Overview

We delivered a high-quality, fully insulated temporary classroom building, designed for year-round use. This modular timber frame structure was constructed to meet educational needs quickly, efficiently, and within budget.

✅ Why a Temporary Classroom?

The client needed additional learning space to accommodate student growth without committing to permanent infrastructure. This solution provided:

• Fast-track installation
• Sustainable materials
• Full compliance with educational building standards
• High levels of insulation and comfort

🏗️ Phase 1: Demolition and Groundworks

Our team began with site clearance and ground preparation, ensuring a solid and level base for the modular classroom.

Demolition works included:

• Removing old sheds and existing concrete base
• Excavating and removing excess topsoil

Groundwork included:

• Installation of 300mm MOT Type 1 base
• Concrete slab with shuttering and visqueen membrane

🏠 Phase 2: Temporary Classroom Construction

We used a timber frame construction system, offering speed, flexibility, and cost-effectiveness — ideal for educational environments.
