I really do not like kids toys at the entry to a home , Whynot just a great piece of art and a nice bench for guests to use to take off and put on shoes . I do not know about your kids but not many I know ever really put away toys . Lego are wonderful but stepping on a pice is not . Keep this stuff in a space wher eit does not matter if all are put away.

Try this: Take ALL the stuff away and put your kids' Legos out. The first time you step on one, you may decide to move them back to the kids' rooms.

If it works for your family, use the space as is. Legos will be replaced by teen things in a few short years, so specialized furniture for Legos will be temporary.

If it’s true that guests do not use the front door, the use that entry space as you see fit. Provide a TON of storage. That rolling table you posted looks good, and should hold most of the blocks. Encourage the kid(s) to put the blocks away! That should cut down on foot injuries.

I think you should use the space in a manner that works for your family, and if that is for toy storage, a desk, additional shelving, or whatever, so be it. Those of us whose children are no longer young or who are out on their own now, can and will decorate for our own needs, with an eye to creating spaces that will appeal to our guests. But as I recall from when my kids were young, most of the 'guests' that came to our house were either the kids' friends, family members, and our own friends, who usually had children of their own, and none of these people would object to seeing toys and other evidence of young people in the household (high chairs, a stroller, maybe a baby gate or a playpen). For heaven's sake, it is their home, too!

Now, while I have made many efforts to remodel (kitchen, baths, bedrooms) and redecorate (FR, LR, DR), we babysit 1-2 times each week for our 2 y.o. grandson. We have a portable crib in his mother's childhood bedroom, with toys on the shelves for him, and more importantly, the slightly raised (3") hearth in the FR is home to multiple toys, blocks, magna-tiles, and children's books, because we like to have him play in this room so both of us can watch him. It is certainly not "magazine ready," but we keep it tidy and he is learning to put things back (when he feels like it). If I was formally entertaining, this cache would be moved to a bedroom, but we don't waste time hiding it, knowing that he could be staying over any time. It is also fine with us for when our two other grandkids come (6 and 2 1/2), and we can watch all three cousins interact, and keep an eye on them from the kitchen.

Since your entry is not normally used, I think a Lego storage set up is a good idea, though a large Lego building table may not be. Where do the children build now? The shelving you showed is beautiful, but I don't think that space is appropriate for it. Maybe built in cabinets below, with a surface for decorative items and a lamp, and artwork above, would add some storage for the legos below and a more sophisticated look above. Then you could build, or buy, a large tray (something like the top of a large ottoman-coffee table) for the children to build on (removable, so it can be put away). Creations they want to save could be displayed in their bedrooms. Good luck!
