You can increase the space by combining the rooms is not a very practical way, since by removing the walls, we will increase the number of premises, which with a large number of living people makes life more complex. This applies to both residential premises and a bathroom – the line in the bath and the toilet will be provided.
In the loggia you can make an office by removing the wall under the windowsill or simply by hearing and equipping a glazed loggia or a balcony.
It is possible to significantly “expand” the space of the room, dividing it into zones. To arrange the hallway, make it bright, which also expand the apartment visually, since people will not strive to quickly go from a passerby to living rooms.
If there are nowhere to store things, it is worth highlighting a place under the dressing room – if it is high in the height of the ceilings, it will be very roomy. Instead of swing doors, you can use sliding or blinds. Thus, you will save the floor area on the cabinets, because all things will be stored in one place.
For a visual increase in the volume of the room, you can use mirrors, change the color scheme of walls, use stained glass windows in the doors and partitions. And do not forget about the lighting – the better the room is lit, the more it seems, because the shadows conceal a significant part of the volume.
The design of the rooms should be simple, but good-without excessive variegation, with 1-2 bright spot (picture, clock or lamp) will distract attention to themselves, and small dimensions of the room will become less noticeable.
Well, if you decide to choose the wires for electricity to the balcony or the change of wires in the apartment, look at the SIP 2 or other brands wire, since the choice is huge. It is better, of course, to consult with a specialist on the site.
