The panel sits exactly where the feature wall ought to be. A cupboard seems like a civil solution, provided everyone agrees that it will not become a cupboard full of things.
Draw the space in use
Show the panel, proposed door, shelving, trim, and the route to it. Ask the electrician to confirm the applicable working-space and location requirements for the actual installation. Do not reduce the question to whether a door can technically open.
ESA's equipment-access notice warns against obstructing electrical panels and equipment. A finished enclosure needs to respect that access after the renovation, not just on inspection day.
Separate concealment from storage
A discreet door may be possible in a suitable design. Shelves, hanging clothes, cleaning supplies, and a deep cabinet introduce a different use. Make the intended purpose clear to everyone who will occupy the basement.
Check the finished details
- Door swing and access to the working area.
- Clearances after the flooring and wall build-up are complete.
- Whether the proposed location and enclosure are permitted.
- A recognizable access point that stays free of stored items.
Arrange required electrical notifications and inspections for altered work. Decorative carpentry should follow the electrical plan rather than forcing it to adapt at the end.
The practical next step is to make the panel easy to find and uneventful to reach. It can be visually quiet without becoming a puzzle. The best concealed detail still works for the person who has never seen your renovation drawings.
