This was a really enjoyable project. My son has boxes and boxes of Lego. Rather than stack them in a corner and continue to vacuum up stray pieces, I decided to make our letterbox for a new house that we are building this year. It will be a talking piece for our new neighbourhood, and will remind us of my son's happy building times. I had a lot of fun using the men in random places – check out the number.

Step 1: The Right Size
I made my letterbox big enough for a C4 envelope, those big envelopes which hold an A4 sheet of paper. I purchased a 30x30cm baseboard from www.justbricks.com.au.
(628 LEGO® X-Large Grey Baseplate CODE: 628)
You may be able to think of a way to use what you have rather than buy something new.
I began by adding a single row of two dots in from the edge of the base plate, on three sides (you can see that in the finished image too), but at the back I left 6 rows of dots, but you don't have to. I don't really know why I did that... I just liked the look of it.
Step 2: Postal Slot
I used Atlantis column pieces to make the edges of the opening, 4 pieces high to allow small packages to be left. The width of the opening is 36 dots – check that a C4 envelope fits before glueing.
I carefully selected the colour scheme for the front, sticking to black and grey pieces mostly, so that my number 37 would stand out in yellow/orange. I glued the pieces one by one with a plastics glue called Tiger Grip.
Step 3: Building It Up and Adding the Street Number
You can have your post box however high you like. And as long as your cover will spread past the finished shape, like eaves on a house, then it doesn't matter if you have some gaps between your Lego pieces.
I built my number first and then added dark colours around to ensure it stands out. Have fun with the Lego people!
Step 4: The Roof
You can use anything waterproof for the top, but I would make sure it extends past the shape of the letterbox, in case you have gaps (which I do) between Lego pieces. I used a plastic box lid and glued it into position.
I love my Lego letterbox.
