The Australian architect is dwarfed by his incredibly detailed Lego model, which is the tallest in the country at a remarkable 5.7 metres high.
Father-of-two Mr McNaught will display his sculpture, which took 250 hours to make, at the Brickvention event in Victoria this month.
The Melbourne-based artist has populated his wonderful construction with tiny Lego astronauts, fuelling up the rocket ship, travelling in Nasa's astrovan and even stopping for lunch.
A few droid stowaways are also amusingly scattered around Mr McNaught's impressively accurate rocket. On the launchpad, figures chat on walkie-talkies, while men in hard hats swarm around the ship adding finishing touches.
The astonishingly realistic model even has cutaway sections so that people can look at its workings on the inside. Its exterior displays the U.S. flag, plus an extra little plaque reading 'Certified professional Ryan McNaught'. –MOL
Apollo 11 landed the first humans, Americans Neil Armstrong and Buzz Aldrin, on the Moon in July 1969. The mission is considered the biggest accomplishment in the history of space exploration.
Nasa launched 13 Saturn Vs from the Kennedy Space Centre in Florida and it remains the tallest, heaviest and most powerful rocket sent into space.
The artist, who calls himself The Brickman, believes he 'never grew up'. The married father of twin boys was previously an IT manager and is now one of only 13 certified Lego professionals in the world.
'My creativity was limited and bound by the constraints of my job, however the ability to express and create through a unique medium offered me an amazing opportunity, the ability to create something that both children and adults alike can be inspired by,' he writes on his website.
'Making interactive models and build experiences is my speciality, building things that people can not only be inspired by but interact with allows an amazing flexibility.
'Giving a remote control or allowing people hands-on exposure in the build process really does make for a great experience. 'I have also been lucky enough to win many awards over the years for my models and I look forward to inspiring more and more people with my creations.
'When I am not playing with little plastic bricks, I love to spend time with my family,' he adds.
