There is a moment every DIYer knows a car full of flat boxes carried through the door, stacked in the kitchen, and a stare that says: where do I begin? Flat pack kitchen cupboards have a reputation for complexity, but a well-planned assembly goes smoother than most expect. The key is a logical sequence, the right tools, and patience before you open the first box.
This guide covers the full process from unpacking to hanging wall units and fitting doors in a way that works whether you are a confident DIYer or picking up a screwdriver for the first time. Follow it in order and the result will be a kitchen that looks like a professional fitted it.
At Dynasty Importers, we supply flat pack kitchen cupboards designed for DIY assembly without specialist tools. These instructions are written with our range in mind but apply across virtually every flat pack system available.
Before You Start: Tools, Planning, and the Mistakes Worth Avoiding
Good preparation is the difference between a smooth weekend project and a week of frustration. The tools you will need for a standard flat pack kitchen assembly are modest: a rubber mallet, a cordless drill, a spirit level, a tape measure, a pencil, a stud finder, and a set of Allen keys. A second pair of hands is not a tool but is equally essential wall units are genuinely difficult to hang solo.
On the planning side, draw your kitchen layout to scale before opening a box. Mark windows, doors, and plumbing. Locate wall studs you will need them for wall cabinet fixings. Confirm the plinth height: the Australian standard is 150mm, but check your specific product first.
The most common mistake in flat pack kitchen installation is starting with wall cabinets and discovering the floor cabinets do not align with them. Plan the full layout before fixing anything permanently.
Assembling Kitchen Cabinets: The Base Units First
The correct sequence for any kitchen installation is base units first, then wall units, then doors and hardware. Assembling kitchen cabinets in this order keeps the work logical, prevents rework, and means your benchtop template or worktop can be measured and ordered at the right stage.
Step 1: Unpack and Identify Every Component
Open each flat pack box and lay out the components on a clean, clear floor space before assembly begins. Match every piece against the parts list in the instruction sheet. Check for damage chipboard edges, hinge holes, and dowel sockets are the most vulnerable points in transit. Raising a damage claim before assembly is straightforward; raising one after is not.
Step 2: Assemble the Carcass
Insert cam locks into the pre-drilled holes on the side panels. Tap dowels into the base and top panels using a rubber mallet never a metal hammer, which splits chipboard edges. Connect side panels to base and top, engaging cams with a screwdriver and rotating until firm. Do not overtighten the carcass needs to remain slightly flexible until squared.
Step 3: Square the Carcass
Before inserting the back panel, measure diagonally corner to corner in both directions. Both measurements must be identical. Apply gentle pressure to the longer diagonal corner if needed, then slide the back panel into its channel. The back panel locks the carcass square this step is frequently skipped and is the cause of most assembly problems further down the line.
Step 4: Fit the Plinth Legs
Snap adjustable plinth legs into their clips on the underside of the base panel before standing the unit upright. These allow individual levelling on uneven floors. Aim for a finished plinth height of 150mm unless your design specifies otherwise.
Flat Pack Kitchen Assembly: Setting Out and Levelling Base Units
With your first carcass assembled, the next stage of flat pack kitchen assembly is setting units in position and levelling correctly. Australian concrete slab and tiled floors frequently vary by 10–20mm across a kitchen run more in older homes. Identify the highest floor point by measuring to your plinth line at multiple positions. This high point sets your datum every cabinet levels up to this height on its adjustable plinth legs.
Place the first base unit in the corner and adjust legs until the top panel sits on the plinth line. Spirit-level the top in both directions. Move to the adjacent cabinet, check tops are flush using a straightedge, and connect the two through their side panels using the provided screws typically two screws per joint, inside a drawer or shelf cavity. Continue along the full run before fixing anything to the wall.
DIY Kitchen Installation Tips: Hanging Wall Units Safely and Accurately
Wall units must be secure enough to safely carry loaded contents overhead these DIY kitchen installation tips apply regardless of the system you are using.
Mark the Hanging Rail Position
Most flat pack wall cabinets hang from a horizontal metal rail fixed to the wall. Mark the rail height across the full run before drilling. The standard position places the underside of the wall unit 450mm above the benchtop itself at roughly 900mm from finished floor level. Confirm this against your specific layout before committing.
Fix Into Studs or Appropriate Anchors
Australian wall framing is typically timber studs behind plasterboard at 450mm or 600mm centres. Locate studs with a stud finder and fix the hanging rail with 75mm screws directly into them wherever possible. Where studs are absent, use toggle bolts or cavity anchors rated for the load standard plasterboard plugs are not adequate for a full run of loaded wall cabinets.
Hang, Adjust, and Connect
Hook each wall cabinet onto the rail and use the adjustable internal brackets to set height and level. Once adjacent cabinets are level and aligned, connect them through their side panels using connecting screws the same method as base units. Check faces are flush before tightening fully.
Kitchen Renovation Guide: Fitting Doors, Drawers, and Hardware
This is where the kitchen starts to look like a kitchen. The kitchen renovation guide principle here is patience doors and drawers take time to adjust properly, but getting them right separates a professional finish from an amateurish one.
Fitting Concealed Hinges
Press the hinge cup into the pre-drilled hole in the door and secure with the provided screws. Hook the hinge arm onto the mounting plate inside the cabinet. Most concealed hinges offer three-way adjustment height, depth, and lateral alignment. Adjust all three until the door sits flush, level, and parallel to adjacent doors with a consistent 2mm gap throughout.
Installing Drawer Runners and Faces
Follow the manufacturer’s measurements precisely when positioning drawer runners height and front-to-back position determine whether the drawer face sits correctly in the opening. Test each drawer through its full travel before fitting the face. Fix drawer faces from inside through adjustment slots, fine-positioning before tightening screws permanently. Drill handle holes from the front face to prevent breakout on the visible surface.
The Finishing Touches That Make the Biggest Difference
The difference between a kitchen that looks assembled and one that looks installed comes down to the details most guides skip.
Plinth panels clip onto the adjustable legs and should be cut to length with a fine-tooth saw to fit neatly between cabinet runs. Use a plinth joining clip at every section joint to keep them flush and gap-free. Filler panels the narrow strips closing the gap between an end cabinet and a wall should be scribed to the wall profile rather than cut square. Walls in real kitchens are rarely perfectly straight, and a scribed filler looks intentional where a square-cut one looks like an afterthought.
Where cornice and pelmet mouldings are included, glue and pin them to the top and bottom of wall units respectively. A mitre box keeps corner joints clean. Wipe away any PVA squeeze-out immediately before it skins over. Finally, fit the soft-close buffers inside every door and drawer opening that does not already have them they prevent the slamming sound that makes an otherwise excellent kitchen feel cheap.

Frequently Asked Questions
2. Do I need special tools to assemble flat pack kitchen cabinets?
No specialist tools are required. A cordless drill, spirit level, tape measure, rubber mallet, Allen keys, and a pencil will cover the majority of the job. A stud finder is essential for wall unit installation.
3. What order should I assemble a flat pack kitchen?
Always assemble base units first, then level and connect them, then hang wall units, and finish with doors, drawers, and hardware. Fitting the plinth and any cornice moulding comes last.
4. How do I level kitchen cabinets on an uneven floor?
Use the adjustable plastic plinth legs supplied with the cabinets. Start at the highest point of the floor and adjust each unit's legs until the top panels are all level and flush with each other. A long spirit level across multiple units helps identify any inconsistencies.
5. How do I get even gaps between kitchen cabinet doors?
Adjust the concealed hinges using their three-way adjustment screws height, depth, and lateral position. Work systematically across each door rather than adjusting one at a time. Aim for a consistent 2mm gap between all adjacent doors.
6. Can I install flat pack kitchen cupboards by myself?
Base unit assembly and installation can be done solo. Wall units should always be hung with a second person present holding a cabinet overhead while simultaneously positioning and drilling is not safely achievable alone.
7. What is the standard height for kitchen wall units in Australia?
Wall units are typically positioned 450mm above the benchtop, with benchtops sitting at 900mm from finished floor level. This places the underside of wall units at approximately 1350mm from the floor, though this can be adjusted to suit ceiling height and personal preference.
