you can use wall panel to cover the cables. there must be a hole on the panel behind the tv. for switch you can make one more hole and move your switch on the panel.

Tsilanko, I would always recommend professional installation where needed. But what I am doing here is suggesting that WHEN you are planning to build or renovate, to consider how your plans will affect you in 20 or 30 years time. Split levels are very hep when you are young. A kitchen 3 steps down at 30 is rarely a problem, but might be a hazard at 60, or, as Marjie1059 suggested, if you break a leg. ... All my parents' homes were terrible for old people. They were forced to move to a bungalow in extreme old sge because the location and design of their home was more suitable for an active young couple with a large family than for an elderly couple with stroke disabilities. I would not want to move again, so my present home has features built in that make ageing in place simpler. Mostly small changes, like grab rails, and lever handles on doors and faucets. A major disability suddenly suffered requires major changes if permanent. I did look at this because it came up in the discussion, but if you look at the heading, Planning for Disability, it means just that. Plan ahead so you don't have to make expensive changes later on. But thank you for your advice, yes, major changes are not in the DIY domain.

For new homes: 1. Window Height. Installing windows that are at least 3.6 feet high helps indoor air movement and also reduces the heat load on ceilings. 2. Wind/Air deflectors. These can be positioned either horizontally or vertically to redirect air flow and can be installed in the form of overhangs, louvers or slats and should be placed on a higher level to redirect air motion. 3. Clerestories. Clerestories not only provide natural illumination, but can also improve air movement. Since hot air is known to go upward, a clerestory is able to act as a vent and space for the hot air to accumulate. 4. Window orientation. Windows should be placed on the north and south areas for optimum cross-ventilation, unless it hinders aesthetic views. This encourages natural breeze and draws in good air flow into interiors, especially during the summer months. 5. Transitional spaces. Incorporate courts, balconies, atriums and other open spaces that encourage air flow.
