At Hayes Cabin Services we deliver high-quality custom modular buildings for pharmaceutical, manufacturing, engineering and construction clients across Ireland.
From offices and canteens through to laboratory and clean-room support spaces, modular lets us deliver flexible, durable buildings at a fraction of the time and disruption of conventional construction.
Four phases. One supplier.
Revit Design
Detailed 3D modelling in Revit, refined with you before any cut is made.
Modules built off-site
BCAR-compliant timber-frame modules, built to order off-site in a dedicated production facility.
Assembly on site
Assembled on your site by our own team, lifted into position by our fleet of truck-mounted cranes.
Fit-out on site
Fitted out on site: electrics, plumbing, HVAC, networking. Operational on handover.
Designed in Revit
Our experienced engineers work closely with you to bring your vision to life. We start by understanding your specific requirements, ensuring every detail is considered. Using advanced Revit software, our team creates detailed 3D models of your custom modular building, allowing you to visualise the final product with precision. This collaborative approach ensures the design aligns with your needs: whether that’s a unique layout, non-standard footprint, or specialised features for a regulated environment.
Detailed 3D modelling, refined with you, before any cut is made.
Built off-site
Once the design is finalised, your modular building is built to order at a dedicated off-site production facility. Modules are built to BCAR (Building Control Amendment Regulations) requirements using timber-frame construction: engineered for durability, thermal performance, and full compliance with Irish building regulations.
Throughout this phase we maintain design oversight: close communication, scheduled progress updates, and sign-off against the agreed 3D model. Every module is inspected to spec before transport.
BCAR-compliant. Inspected to spec before it leaves the facility.
Assembled by our team
When the modules arrive on your site, our team takes over. With our own fleet of truck-mounted cranes, we manage transport, lift each module into position, link the units, and stage the building ready for fit-out.
Because the assembly is in-house (our crews, our cranes, our schedule) site work runs on our terms. No separate crane contractor. No third-party haulier. No coordination gaps.
Our team. Our cranes. Our schedule. No third-party delays.
Day-one ready
In the fit-out phase, we transform the assembled structure into a fully functional space. Our team installs custom electrics, plumbing, climate control, networking and any specialist features your operation needs: whether that’s specialised lighting, advanced HVAC, or integrated technology. This is where the building comes to life, equipped with the amenities and systems required for day-one operation.
Operational on handover. Day-one ready.

Do you deliver across Ireland?
Yes. Every Hayes Cabin Services unit is delivered nationwide from our base in West Cork. The truck-mounted cranes in our fleet lift the unit off the truck and position it exactly where you need it on-site, so no separate crane is required. RAMS and a lift plan produced by our appointed person are issued in advance for every delivery as standard, and all lifting equipment is GA1 certified.
How quickly can you deliver?
Most deliveries are scheduled within 48 to 72 hours of order confirmation, subject to stock and route. For specialist modifications or bespoke builds the lead time is longer. We’ll confirm a firm date in writing before invoice.
Can I hire instead of buy?
Most units in the range are available for sale or hire. Hire works on weekly or monthly rates with delivery and collection included; sale is a one-off purchase. Long-term projects under roughly 18 months usually work out cheaper on hire. We’re happy to price both options side-by-side.
Do you provide RAMS and delivery paperwork?
Yes: Risk Assessment and Method Statement documents are issued in advance of every delivery, covering the lift, the site approach, and our banksman’s role. We can route paperwork through your procurement system if required (PDF, portal upload, or signed hard copy on arrival).
