Maximising space in a box room for a standard double bed and extensive storage

Reclaimed oak shelves to match the window sill; colour-matched yellow wardrobe interiors; secret storage hatch in bottom shelf - great for storing extra bedding; narrow wardrobes to maximise floor space with front-back extending rails; deep under-bed drawers with heavy duty rails to hold extra weight; power points in headboard and bottom shelf for a night light and phone charger; standard double-bed; the grain of the wood is matched across drawers (see close up images)
