This room had a fitted wardrobe, that had been removed. Leaving a recess of 10 mm plaster.
We plastered the recess area to leave a level surface, re-boarded the ceiling recess and plastered. Then painted the room in white mat emulsion. To leave a smooth finish. Re-routed the old heating pipework to run under the floor boards. Fitted new skirting board. You would never know there had been a wardrobe fitted. Before and after pics below.
