MIDDLESEX LTD

Design

Middlesex Design is our in-house solutions-driven team created to meet the demanding requirements of modern Design and Build contracts and performance-led fit-outs. Made up of qualified architects, interior designers and BIM specialists, the team combines technical knowledge, practical experience and creative thinking to deliver buildable detail from concept to completion. Our objective is simple: to make every design decision add value — for the client, for the installer, and for the building itself.

WHY US

Choose Piece of Mind

Architectural expertise

Qualified architects and interior designers translating concept intent into buildable construction detail.

BIM capability

Fully resourced team supporting Revit, Navisworks and industry-standard coordination platforms.

Practical grounding

Every designer completes regular on-site installation days to British Standard BS EN 1363-1, linking theory directly to practice.

Collaborative culture

Design Managers and BIM Managers work side by side, sharing learning across projects through twice-weekly reviews and internal CPD sessions.

Early engagement

We add the most value when involved from Stage 3 or pre-tender, providing specialist advice and tested solutions before drawings are fixed.

What We Do

Middlesex Design translates Stage 4 information into coordinated models and working drawings that hold equal value for the design team, the main contractor and our site installation crews. We refine layouts, develop details and confirm tested wall and ceiling assemblies, ensuring every component aligns with project specifications and the fire, acoustic and structural requirements set out at design stage.

Our team handles the full scope of design support:

  • Coordination of architectural and M&E information within the BIM model
  • Production of construction and fabrication drawings
  • Validation of manufacturer details and tested systems
  • Integration of programme and sequencing logic into the model
  • Output of data to support QA and Building Safety documentation

Every drawing and model we issue is practical, traceable and aligned to the way the project will actually be built.

How We Work

The Middlesex Design process is highly collaborative. Design Managers and BIM Managers are assigned to projects but operate as one collective, sharing technical insight and workload across the department. The team meets at least twice weekly for design reviews, problem-solving sessions and internal CPDs. This environment encourages rapid decision-making and consistency across all projects — whether we are working on a high-compliance healthcare facility, a Cat B office fit-out or a large residential development.

Each project follows a clear structure:

  • Information intake – Stage 3 or 4 drawings are received, reviewed and coordinated.
  • Buildability review – Key junctions, tested details and sequencing implications are assessed against our internal benchmarks.
  • Model integration – Drawings are translated into coordinated 3D models for issue to design teams and clients.
  • Site validation – Designers regularly attend site to confirm that design intent translates accurately to installation.
  • Evidence and output – All drawings, models and RFIs are traceable to the quality assurance and Building Safety framework.

This process gives clients confidence that what is drawn can be built, and that what is built can be evidenced.

Why It Matters

Good design is not just about visual intent — it is the foundation of buildability, safety and programme certainty. Middlesex Design acts as the technical bridge between concept and delivery, ensuring every decision supports efficiency, compliance and finish quality.

When we are involved early, we can simplify interfaces, reduce RFIs, and identify cost and time savings long before mobilisation. Our insight into fire-rated systems, acoustic performance and structural detailing allows us to make proactive suggestions that protect both design integrity and commercial targets.

In an industry where design and construction are often disconnected, Middlesex Design creates alignment — turning design intent into predictable, compliant, and verifiable results on site.
