Our Story Across Engineering and Fashion Goods
Our work reflects a singular focus: distilling complexity into elegant high-performing solutions - across both engineering and fashion goods
Grandiair® is an independent multidisciplinary building services engineering consultancy driven by a clear vision: to deliver excellence across both technical engineering and contemporary design. Specialising in Mechanical, Electrical, and Public Health (MEP) engineering design for buildings, we provide tailored solutions that prioritise performance, compliance, and clarity up to RIBA Stage 4. With decades of industry experience, we combine technical expertise with a streamlined, client-focused approach. Every project is approached with precision, attention to detail, and a commitment to high performance and best practice standards. Where equipment is supplied under our brand, it forms part of a fully engineered solution and is provided subject to clearly defined installation commissioning and maintenance requirements, ensuring performance and reliability throughout the system lifecycle.
Alongside our engineering expertise, we extend our commitment to precision and quality into the fashion space - where we will be offering a refined line of apparel and accessories that reflect the same values of thoughtful design, functional elegance, and attention to detail.
Whether shaping building systems or signature styles, we approach every project with the same dedication: simplified in design, uncompromised in performance™.
Our Approach
At the core of everything we do - whether designing building systems or crafting fashion goods - is a commitment to purposeful, high-performing solutions.
In engineering, we take a client-led, compliance-driven approach. Our MEP consultancy services focus on clarity, coordination, and practical delivery. Every design decision is backed by technical expertise and shaped by the needs of the end user, ensuring our mechanical, electrical, and public health systems work seamlessly within the built environment.
Our engineers take the time to understand your specific goals, site constraints, and end-user requirements. We prioritise design clarity and buildability - helping clients move confidently from planning to delivery. Each design is developed with:
-
Clear communication and collaboration from early stages.
-
Attention to coordination with electrical, public health, and structural systems.
-
Use of industry-standard software for precise modelling and analysis.
-
Full compliance with CIBSE guidelines, Building Regulations, British Standards and applicable environmental standards.
In fashion, our process is guided by the same principles. We create elevated garments and accessories that balance form and function. From fabric selection to final detailing, each piece is refined with intent, built to perform, and styled to last.
Across both disciplines, we value feedback. Listening to our clients and customers fuels continuous improvement. It informs how we solve problems, where we innovate, and how we raise the bar on quality and usability.
The result is a unified design philosophy - grounded in precision, elevated by experience, and always driven by the end goal: better performance, for people and the environments they move through.
