Design a Logo

Hi there! I need a flat logo featuring a 'cube' for a brand called RoomBox or ROOMBOX (capitalisation is flexible at this stage). I already have three versions of the logo from another designer (as attached). What I like about V3 is the slick shape of the cube with rounded corners. What I do not like is that the icon is separate from the name ROOMBOX. I would like the brand name to be incorporated in the cube somehow, which is what the designer tried to do in V1 and V2, but unfortunately none of these these looked good. For example, in V1 the cube looks more like a hexagon (i.e. two-dimensional), and in V2 the cube is visually broken by the line in the middle while the "R" just looks random. So I'm looking for a fresh pair of eyes and someone with ideas of how to incorporate the brand name into the cube in a way that looks visually appealing and without compromising the 'structural integrity' of the cube. So I guess the logo type is what Freelancer calls 'Logo System' (e.g. MTV logo) where the name and icon are combined. I need to be able to engrave this logo in metal so it must work in black and white. And also it needs to be able to fit into social media profile pictures (so fit into a square or a circle). Brief description of the business: RoomBox manufactures standalone garden rooms / offices / studios, which clients then put in the back of their gardens to create additional living or working space (picture example attached). The rooms are insulated, heated, connected to services and built to exceptional quality. Happy to provide any additional details or discuss concepts. Many thanks! Roman
