Perfect scale with perfect detail!

I bought this item for myself as I had a UK trip planned but unfortunately was unable to travel this year. This set has outstanding detail for it’s size, everything from the little black London cabs to the double decker red buses! As far as shelf presence goes this is now the centre piece for my Lego Architecture builds and looks fantastic alongside them. I recommend this for anyone aspiring for a visit to London or even fans of intricate and detailed Lego builds.

All the Browny Points!!

Imagine my predicament - its the weekend before my wife's birthday and no presents have been organised. Then I remember that she mentioned a liking for Lego architecture and we just finished showing the kids our photos from our long ago trip to London. That's when Inspiration hit and I jumped online, found Myhobbies and then instantly found Trafalgar Square Architecture kit. I snapped that thing up quicker than my kids on a PS Controller and paid for express postage, hoping like heck that all the stars would line up and we would receive the package in time. Lo, the electronic mail man delivered the best news the next day; that the package was already on its way and should arrive later in the week. Then the glorious man in the Aust Post uniform arrived at our door THE VERY NEXT DAY, delivering the goods. The minister for finance was more than pleased upon opening her gift, and all the browny points were earned with her thinking that some long and arduous task had been performed to get her such a thoughtful gift.

A work of art!

My 12 year old loved building it. It’s fun and not too complex. Now it’s on display...until the next one.
