How to Build a Stud Wall
Divide a room cleanly and cost-effectively with a timber stud wall you build yourself.
To build a stud wall, fix a timber sole plate to the floor, a head plate to the ceiling, and vertical studs between them at 400mm or 600mm centres. Nail noggings between studs for rigidity, then fix plasterboard to both faces before skimming or taping and jointing.

Step-by-Step Guide
Plan and Mark the Wall Position
Decide where the wall will run and mark a straight line on the floor using a chalk line or straight edge. Use a plumb bob or long spirit level to transfer this line to the ceiling directly above — accuracy here prevents a leaning wall. Check for any pipes, cables, or joists hidden in the floor and ceiling using a stud finder before committing to the line. Refer to our Carpentry & Woodwork Guide for general framing principles if you are new to structural timber work.
Fix the Sole Plate and Head Plate
Cut the sole plate and head plate to length — these are the horizontal timbers that run along the floor and ceiling. Fix the sole plate first, drilling through it and into the floor at 600mm intervals using frame fixings or masonry anchors as appropriate for your floor type. Hold the head plate against the ceiling on your marked line and fix it the same way into ceiling joists wherever possible. If you cannot hit a joist, use suitable cavity fixings or a timber batten across multiple joists to carry the load.
Install the End Studs
Measure and cut two vertical studs to fit snugly between the sole plate and head plate — the fit should be firm, not forced. Fix these end studs to the existing walls using frame fixings, ensuring they are perfectly plumb in both directions with a spirit level. These end studs carry the tension of the whole frame, so solid fixing here is critical. If you plan to hang a door in the wall, position one end stud to form the side of the door opening and add a doubled-up stud and head for the door frame at this stage.
Space and Fix the Intermediate Studs
Mark stud positions at 400mm centres for 12.5mm plasterboard, or 600mm centres for 15mm plasterboard — measure from the same starting point on the sole plate each time to keep board joints consistent. Cut each stud to length, toe-nail or skew-screw it through the base into the sole plate, and fix the top the same way into the head plate. Check each stud is plumb before moving to the next. If you are adding acoustic insulation, cut mineral wool batts to fit between studs and push them in at this stage, before boarding begins.
Add Noggings for Rigidity
Cut horizontal noggings from matching timber and fix them between studs at mid-height — typically around 1200mm from the floor. Noggings prevent the studs from twisting under the weight of plasterboard and give you a fixing point for any wall-mounted items such as radiators or shelving brackets. For a partition over 2.4m tall, add a second row of noggings. Stagger the noggings slightly so you can skew-nail each end from the front face without the nail fouling the opposite fixing. If you plan to replace skirting boards after boarding, add a low nogging at skirting height for a solid fixing.
Board and Finish the Wall
Fix plasterboard to both faces of the frame using plasterboard screws at 150mm centres into studs and noggings — screw heads should dimple the surface without breaking the paper face. Stagger board joints between faces so they do not line up back to back. Once boarded, you can skim plaster over the whole surface or use a tape-and-jointing system to fill joints and screw holes. Either finish brings the wall to a paint-ready surface. Once the finish is set, painting the new room is straightforward with two coats of emulsion over a mist coat on fresh plaster.
Frequently Asked Questions
Do I need building regulations approval to build a stud wall?
Most non-structural internal partition walls do not require building regulations approval, but if the wall affects a means of escape, fire separation between rooms, or structural elements, you should check with your local authority building control. The GOV.UK building regulations page outlines when approval is needed.
What size timber should I use for a stud wall?
For a standard partition wall up to 2.4m tall, 75mm × 50mm sawn timber is sufficient for both plates and studs. For taller walls or where improved sound insulation is needed, 100mm × 50mm gives a deeper cavity for thicker acoustic insulation batts.
How do I improve the soundproofing of a stud wall?
Fill the stud cavity with acoustic mineral wool insulation and use 15mm acoustic plasterboard on both faces instead of standard 12.5mm board. For serious sound reduction between rooms, a double-stud wall with an air gap between the two frames significantly reduces flanking transmission. Our Carpentry & Woodwork Guide covers advanced framing options in more detail.
Can I fix heavy items to a stud wall?
Yes, provided you fix directly into the timber studs or into noggings you have deliberately installed at the right height. Use a stud finder to locate the timber framing — plasterboard alone will not support shelving, radiators, or wall-mounted televisions safely.
How do I finish a stud wall after boarding?
You can either skim the entire surface with a 3mm coat of finishing plaster for a smooth, paint-ready result, or use a tape-and-jointing system to fill the joints and screw holes without plastering the whole wall. Both methods work well — plastering gives a harder surface, while tape-and-joint is faster and easier for a beginner. Once finished and dry, follow our guide to painting a room for a professional result.
Before fixing the sole plate, lay a bead of acoustic mastic beneath it — this breaks the rigid contact between the timber and the floor slab, killing the path for impact sound to travel through the structure. It costs almost nothing and makes a measurable difference to how much noise transfers between rooms.
