Lights, elecs and rads
We’ve retained the existing downlights in the smaller section but suggest replacing the fittings with dimmable directional LEDs- this will give you greater control over the angle and strength of the light- particularly useful in a mixed use space. In the main area we’ve added two downlights in front of the doors but avoided adding a pendant as the ceilings are low. Instead we’ve added wall lights which will provide soft, attractive lighting. We suggest simple plaster fittings which will look like part of the wall and can frame the window (with the amazing view) and the TV area. These are independently controlled so you can create scenes and avoid glare from the stair side wall lights when watching TV.
We retained the existing position of the light switch but changed to a 3 gang dimmer for the room and a single on/off gang for the hallway lights below.
Throughout, we’ve added additional sockets and suggested USB sockets for key areas where you will plug in devices or charge your handheld electricals. The intercom location has also been retained as we think this works well.
As discussed- you may require a fire-safety misting system on this floor- a specialist will need to confirm the best locations, so for now we’ve added a provisional appliance point in the eaves joinery for this.
For radiators- we’ve suggested column rads which will match the rest of the house throughout and can produce a lot of heat without taking up much space. However, if you prefer to keep the top floor more modern, you could use larger flat panel rads instead. The required BTU for the whole space is 8956 which the two rads shown in the plan achieve. If you decide to replace the rads and plumbing throughout, you could have the top floor as a separate zone with its own thermostat and controls. We’ve provisionally added a thermostat to the plan for this.
