Our Services
Every floor plate is different. The wall type you need depends on what the space has to do: block sound, preserve sightlines, meet a fire rating, or all three.
We install partition walls from single meeting rooms to full-floor divisions. If you are unsure which type applies, that is what the site measure is for. We also install demountable partition walls for businesses that need flexibility rather than permanence.
Floor to ceiling, tracked to the structural slab above with deflection joints. For meeting rooms, private offices, and any space that needs acoustic separation or a fire rating. Finished and painted like any permanent wall.
Partial-height divisions that separate zones while keeping visual connection. Reception areas, team zones, and open-plan offices where you want definition without boxing people in. Sightlines stay open.
Enclosed rooms need access. We frame hinged, sliding, or pivot doors directly into the wall structure. Trade coordination for electrical, security, and acoustic sealing is included in the scope.
Walls forming part of a fire-isolated corridor, stairway, or exit must achieve the required FRL. Class 5 commercial buildings typically require 60/60/60 or higher with fire stopping at all penetrations.
Walls specified to Rw 35 to 50 depending on construction. Seal specification at head, jamb, and threshold is treated as one scope item with the wall, not bolted on after.
A wall without a door is a boundary. A wall with a door is a room. We frame doors directly into the wall structure during installation. Acoustic seals at the head, jamb, and threshold are specified as part of the wall scope where the wall carries a sound rating. Doors also bring trades together: light switches, access control readers, and mag locks tie into the building's services. Stemar coordinates the electrician and security technician under one project manager so you are not chasing three contractors to get one door working.
The standard for offices and meeting rooms. Single or double leaf, inward or outward swing. We confirm swing direction during the site measure based on corridor clearance and furniture layout.
Space-saving for tight corridors or rooms where swing clearance is limited. Top-hung tracks concealed in the wall head. Good for consultation rooms and small offices off narrow hallways.
Architectural entry for boardrooms and feature spaces. The pivot mechanism sits in the floor and head, allowing wider panels than a standard hinge. Used where the door is part of the design statement.
Every door type gets acoustic seals at head, jamb, and threshold where the wall is sound-rated. Mag locks, strike plates, and reader brackets are coordinated with your security technician under one project manager.
Partition wall projects in commercial buildings carry compliance obligations. Fire ratings, structural requirements, base-building approvals, and council consents all apply depending on the wall location and building class. You do not need to become an expert in the NCC to get your office divided.
Internal walls forming part of a fire-isolated corridor, stairway, or exit must achieve the required Fire Resistance Level. For Class 5 commercial office buildings, this is 60/60/60 or higher. We specify fire-rated wall systems, install fire stopping at all penetrations including electrical and data, and provide certification documentation at handover.
Walls over 3 metres or carrying lateral loads may require engineering certification under the NCC. We engage structural engineers as part of the project scope. In commercial tenancies, walls penetrating or attaching to the base-building structure require building manager or landlord approval — coordinated as part of project management so it does not stall your timeline.
Depending on scope and your local council, a Development Application or Complying Development Certificate may be required before work begins. Our Western Sydney council expertise covers Fairfield, Blacktown, Cumberland, Penrith, and Parramatta. We assess the requirement during scoping and lodge on your behalf.
Full-height walls are tracked to the structural slab above using a deflection head detail that accommodates building movement. Floor tracks are fixed with mechanical anchors. Standard commercial practice. At removal, track fixings leave small penetrations that are patched as part of any standard strip-out.
Installed partition walls are classified as tenant improvements. Make-good obligations commonly require removal and floor plate restoration at lease end unless a make-good deed is negotiated. We raise this during scoping. A demountable system may reduce or eliminate make-good exposure — we will tell you if that applies.
Staged delivery and after-hours work are standard options, not premium add-ons. A three-room partition project can be installed over a weekend. Your team returns Monday to completed walls, painted and finished.
Fixed-price quotes covering supply, installation, trade coordination, and approval documentation. The price does not change after you sign. Scoped by a principal after a site measure, not estimated by a sales rep from a floor plan.
Most office wall partition projects sit inside a broader scope. You need walls, but you also need electrical moved, data points added, HVAC adjusted for the new room layout, flooring laid, and everything painted. Running those as separate jobs with separate contractors costs more and takes longer than scoping them as one managed project under a single project manager and a single fixed-price quote.
Walls, electrical, data, HVAC, flooring, and painting bundled under one fixed-price quote that holds from start to handover.
Every trade coordinated by one principal with direct phone access. No coordinator escalating every decision to head office.
Scoped for the operations and timelines that businesses across Wetherill Park, Smithfield, and Parramatta actually work to.
