Opening up a stud-partition wall to add a new doorway is one of the most practical renovation moves in a home, holiday rental, or hotel room — it can transform dead-end corridors into connected living spaces. The video above walks through the entire framing process on camera; the guide below adds the planning, safety, and finishing detail you need before you start. Because stud walls are non-structural, most homeowners with basic carpentry skills can tackle this job themselves, but you must confirm the wall is non-load-bearing before touching a single stud.
Is Your Wall Really Non-Load-Bearing?
The single most important check before any cut is confirming the wall carries no structural load. In Greek homes this usually means masonry construction on the outer envelope and concrete columns, with internal stud partitions purely dividing space — but always verify. Run to the basement or look in the attic: if the wall sits above a beam or below a ridge, or if joists run parallel directly above it, treat it as potentially load-bearing and have a structural engineer inspect it before proceeding. Cutting into a load-bearing wall without a temporary support structure and engineered lintel is dangerous and, in Greece, requires a building permit from the local poleodomia office.
If you are working in a listed building, a listed property in a preservation zone (paratiriti oikismoi), or a tourist accommodation subject to EOT standards, check with your local authority or an architect before removing or modifying any wall element. For straightforward partition walls in ordinary homes and rentals, no permit is normally required — but always confirm this in writing with your municipality.
Tools, Materials, and Safety Basics
You will need: a stud finder, spirit level, tape measure, pencil, reciprocating saw or jigsaw, handsaw, hammer, pry bar, 4 x 2-inch (or equivalent 97 x 47 mm) timber for the new frame, a header (lintel) of adequate depth, galvanised joist hangers or structural screws, plasterboard, jointing tape, and filler. PPE is non-negotiable: safety glasses and a dust mask rated at least FFP2 are essential because cutting plasterboard releases fine silica dust, and older walls may contain fibreglass or mineral-wool insulation.
Before you cut anything, switch off electricity at the consumer unit and use a cable and pipe detector on the entire wall face. In older Greek apartments, conduits often run vertically to socket outlets or horizontally to switches at unexpected heights. Water pipes in a stud wall are less common than in masonry but not impossible in renovated properties. If you find live cables or pipes, reroute them first — this is work for a licensed electrician or plumber respectively.
How to Cut and Frame the Doorway
- 1
Mark Out the Opening on Both Faces
Using your stud finder, locate every stud in the section of wall you plan to open. Mark the positions with a pencil line from floor to ceiling on both sides of the plasterboard. Decide on your rough-opening width: for a standard 80 cm interior door, plan a rough opening of roughly 86–90 cm to allow for the door lining (frame) plus a 10 mm gap each side for shimming and squaring. Mark the top of your rough opening — door height plus 5 cm for the lining head plus the depth of your header timber. Use a spirit level to draw perfectly vertical side lines and a perfectly horizontal top line on both faces of the wall.

Cut and Remove the Plasterboard
Set your jigsaw or reciprocating saw blade depth so it cuts only through the plasterboard without biting into the studs behind. Cut along your marked lines and remove the panels in manageable sections. Be gentle around the cut edges — the plasterboard screws holding it to the studs will resist, so use the pry bar carefully to avoid cracking the adjoining plasterboard you plan to keep. Once both faces are opened, you have clear sight of the stud frame inside.

Remove the Studs and Install Temporary Support
Any stud that falls within your rough opening must come out. Before you cut them, nail or screw a temporary staggered support board (a 'needling' board) across the plasterboard on each side of the opening to hold the remaining wall panels in place and reduce vibration. Cut the unwanted studs with a handsaw or reciprocating saw as close to the top and sole plates as possible, then lever them free. If the sole (bottom) plate runs across the doorway, cut and remove that section too, flush with the finished floor level — use a multi-tool or chisel for a clean cut without damaging the subfloor.

Build and Fit the Header and King Studs
The header (also called a lintel or noggin board) spans the top of the rough opening and transfers any load from above to the trimmer studs either side. For a non-load-bearing partition, a doubled 4x2 laid flat is usually sufficient; your structural engineer or a chartered builder can specify depth if there is any doubt. Cut two full-height 'king studs' to fit from the sole plate to the top plate at each side of the opening, fix them plumb, then cut two shorter 'trimmer studs' (also called jack studs) that run from the sole plate to the underside of the header. Nail or screw the header into place on top of the trimmers and check everything is level and plumb before proceeding.

Patch the Plasterboard and Fit the Door Lining
Cut new plasterboard to patch the areas above the header and any gaps at the sides, screw to the studs, tape all joints with jointing tape, and apply two coats of filler, sanding between coats. Once the wall is smooth and primed, install your pre-made door lining kit into the rough opening, packing it with timber shims until it is perfectly plumb and square on all three sides. Fix through the lining into the studs with long screws, then hang the door on its hinges and check it swings freely with an even reveal. Fit architrave to both faces to cover the junction between lining and plasterboard, then paint or finish to match the room.

FAQ
- Do I need a building permit to cut a doorway in a stud wall in Greece?
- For a non-load-bearing interior partition wall in a standard residential property, no permit is generally required under Greek building regulations. However, if the wall is structural, if the property is in a heritage or preservation zone, or if it is a commercial or tourist accommodation subject to EOT licensing, you must consult your local poleodomia authority or a licensed architect before starting work.
- How do I tell if there are electrical cables inside the stud wall?
- Always use a dedicated cable and pipe detector (available in any hardware shop) before cutting. Run it across the entire face of the wall in both directions. Switch the electricity off at the consumer unit before you cut, even if the detector shows nothing — older wiring in Greek apartments is sometimes undetected by basic tools. If you find cables, hire a licensed electrician to reroute them before proceeding.
- Can I do this in a holiday rental or hotel room without a structural engineer?
- If the wall is clearly a non-load-bearing partition (no joists or beams above, running parallel to the floor joists, no evidence of structural connection), an experienced DIYer can do the carpentry. However, for any commercial tourist accommodation in Greece, changes to internal layout may require approval from EOT and possibly a building permit. Always document the work with an architect's sign-off to protect your licence and insurance.
