Building your own kitchen cupboards is fairly easy once you get the hang of it. I'm going to teach you all the ins and outs of the trade as well as what to look out for when you build your own kitchen cupboards.
Before you can even begin to build kitchen cupboards you need to have some sort of floor plan layout. 3d kitchen designs would be a bonus as this will put the entire remodeling project in 3d perspective. The floor plan layout has to have detailed dimensions so that you can see exactly where the kitchen units will go and how they will be placed in your kitchen cupboards. There are free kitchen designs programs that are available. I use Kitchen Draw. It's unbelievably user friendly and has superior 3d photo realistic rendering. You can download it at www.kitchendraw.com.

Once you've got detailed designs of your kitchen cupboards you can start building your kitchen. If you've designed a U shape design kitchen you have to start in the corners of the kitchen. You will first have to place the corner base units in each corner of the kitchen. After that you will follow with the other kitchen cupboards by fixing them to the corner base units.. Make sure your base units are perfectly level before you fix any other cupboards to them otherwise the whole row of kitchen units will be skew. I usually fix cleats 150mm from the floor against the wall to rest the kitchen cupboards on. This forces all the units to line up perfectly against the wall. If you've done this properly all you need to do is place the corner base units in the corner of the kitchen and they will stay there floating perfectly off the ground.
After you've placed the corner units on the cleats you can adjust the pvc legs upon which the units stand down to the ground so that the kitchen cupboards don't fall forward. Once you've made sure that the corner kitchen cupboards are steady you can fix the other units against them.

Because the chipboard used for kitchen cupboards is only 16mm thick you will have to use a 6x30mm chipboard screw to fic the cupboards to each other. If you use a 6x40mm screw it will go right through both sides of the kitchen cupboards. Once you've finished installing the base kitchens cupboards you can move onto fitting the kitchen's wall units. Remember to always line up the floor units and the wall units with each other. If you have a oven in the middle of a row cupboards on the long wall between the two corners you will have to start with the extractor wall kitchen cupboard.
Now that all the kitchen cupboards are in place and level you have to fit the counter tops onto the base units. Allow for a 20-30mm overhang on the ends of the base units. Be very careful when cutting the holes for the hob and sink. If you make a mistake you can't go back and fix it. Measure twice cut once plays a critical part here. Only when you know everything is right do you start cutting the holes. The planning takes 3 times longer than the cutting when it comes to building kitchen cupboards. But remember if you make a mistake you didn't account for it will take you 6 times longer to get the same job done. So take the time to plan it's worth it.

After the worktops have been fixed in place and the hob and sink is fitted to the worktop you can hang the doors and fix the kitchen handles to them. The easiest way to hang kitchen cupboards door is to start by fixing the top hinge to the kitchen cupboards carcass. This way the door will still stay fixed to the cupboard even though the bottom hinge isn't fixed down. After you've mounted both top and bottom hinge to the cupboards carcass you will see that the door pushes away for the carcass a bit once you've closed it. This can be overcome by loosening the screw on the fixing plate of the hinge(the screw that holds the two pieces of the hinge together)and opening the door to a 100' angle. Once you've done that tightened the fixing plates screws and close the door. It should close perfectly now. Be careful when drilling the holes for the cupboards handles. You don't want to drill the holes too far or the close from each other so that they don't line up with the kitchen handles holes.

Now all you need to do is the finishing touches of your kitchen cupboards. Make sure you don't rush the silicone work and filler work. This will depend on how the kitchen will shine at the end. No use you spend 3 days laboring on the structure of your dream kitchen only to have people say the finishing touches look horrific.
Now that you have an idea on how to build your own Kitchen cupboards and where to get designs for the layout of your kitchen you can have fun doing your own project. Drop me a comment if you have any questions or need any help.
