The project turned out to be very light and bright. I think, you can keep the furniture you have. As classic furniture (like antique cabinet and ancient dresser) goes very well with modern and bright one. White floors are solid (epoxy) floors. Or you can make any wood floors. Wood always looks good.
In the pictures there are some minor differences from the planning you sent earlier, but I hope my ideas are clear. In my opinion, it's not necessary to build a wall between the living room and the corridor. You need it, only if you want to put wardrobes along it, if not – it will be better to leave this space open, because it will allow you to have more light.
As for master's bedroom... I don`t know, whether you had the idea to divide the master's bedroom and the bathroom with a glass partition in order to let the natural light come into the bedroom. The advantage of this option is that you don't have to make a bathroom on the balcony. I`m not sure if that's its best position, but I want you to consider all the options.
In the boy`s rooms it is possible to keep all the furniture you already have.
I think everything is clear about Emma`s room:)
Temporary workspace can be small and mobile like IKEA PS 2014 Secretaire 802.607.01 and be placed in the living room or in the kitchen or in the master's bedroom. Or put the table IKEA ALEX 402.607.17 or IKEA MICKE 902.143.08 in the kitchen, then the sofa you already have can be moved to one of the children's rooms.
In the children`s bathroom I would use any white tile, but with some bright grout and contrast stand like in the picture.
I hope you will like it:)
Best regards!
