We all take for granted the work it takes to design and construct a kitchen, as we expect everything to just fit into the space. It actually takes hours of design work to make sure you are getting the best use of your space as we all know how limited floor space is especially in a smaller home. When designing a new kitchen, the main thing that is going to take up space will be your kitchen units, as they will be holding loose object so you aren't left with a cluttered mess with your new kitchen. These will also contain your appliances as well if you choose to go for a built in kitchen if you desire the sleek flush aesthetic a built in kitchen can give you.
When considering your kitchen design, the main thing you want is to not have any wasted space. You also can't have too many units crammed into one space as this is going to cause walkway issues, as well as obstructing units that might block each other when they are open. You might think this process of designing might leave gaps in-between cabinets but there are smaller cabinets that can be installed that ensure you get the maximum use of the space.
The majority of your kitchen units are going to be your single and double wall units as these are going to make up the general units of your kitchen. Single and double units mean just that, singles having one door and doubles have two, giving you more space and a different aesthetic as you are going to have two handles in the middle rather than just on one side.
Top boxes can be described as one of the filler units we mentioned earlier, as they are often used above induction hoods to fill the space so you are still getting more storage space than you would without it. This can also complete the join between two units which you usually have since the cooker hoods are always in-between two units to stop any fire hazards against a wall. The size of the top box will depend on the size of the space left above the hood, as it the height of the cooker hood will dictate the size of the box you need.
End of kitchen units are used for just that, the end of an island or aisle of units if you don't want an abrupt end to your units. These can be tailored to your liking as you can have a mix of designs, either having a door or even a pull out unit for storage. You could also opt for curved shelving on the end of the units but a corner unit is most recommended for the aesthetic values it brings to your kitchen. This again can also act a "filler" unit as you may not be able to fit another normal sized single or double unit so you can opt for a smaller corner unit which is going to hit two tick boxes in one, making extra storage space where there wouldn't be, and giving your kitchen a more refined look.
Corner and angled units are great if you want to introduce something new to your kitchen. These will give you some functionality in the form of more storage as well as some interesting mechanism that make corner units open. There are a variety of options you can go for, including inward corner doors, sliding doors or your traditional curved doors for your corner units.
