Proper and correct calculation is very important in construction. However, it is more important in architecture. This is because it is the design stage that determines how the construction process will proceed. Errors made at this phase can ruin the eventual construction process or make it more daunting than it should be.

This is why architects (in particular) and everyone involved in the business of designing and construction should know how to calculate appropriately. These include carpenters, home renovation experts, electricians, plumbers, and bricklayers. More so the house plan that would eventually be interpreted to become a home is filled with calculations.

One of the plans that require comprehensive knowledge of how to calculate properly is 30X40 House Plans. A great deal of skill is required on the part of the architect and every building personnel to execute this kind of project efficiently.

You’ll find that it is a design that is mostly erected on small portions of land. This places more demand on the skills of those involved to do a great job on the space. We will therefore be taking a close look at 30×40 house plans in this article.

30×40 3 Bedroom House Plans

This house plan is ideal for people who want to build on a limited space. The entire building will take no more than 1200 square feet. So, you might want to consider plans that fall into the 30×40 category if you do not have the luxury of space.

It could also be a great option for people who have a lot of space but want something compact. This would allow them to have sufficient space for other things. A garden, lawn, play area, and pool are examples of things that can be erected on the remaining portion of land.

You should also know that this plan is more about the size of the property than an architectural style. For example, a cottage or cabin-style modern building can be made into a 30×40 plan. There are several things you have to consider when choosing your 30×40 plan. One of the most important is the number of rooms you want on the property. This will influence a lot of other things. One of the most common answers for many is a 3 bedroom 30×40 plan.

A 3 bedroom design most certainly offers enough room for a regular family. You may also be squeezed in space for other activities to be performed in the building. It is important to point out that all of the parts earmarked as bedrooms do not even have to be used for that purpose.

For instance, one of them can be used as a library. If you are going for the 3 bedroom option, here are some things you should take note of:

Have a Comprehensive List of all Desired Features

It is not enough to decide that you need nothing less than 3 bedrooms. You also need to think long and hard about the other features you want in the home. After you have thought about this, then you may need to separate the necessities from things you can do without.

Some of the other things you should think about include the availability of a parking garage, hallway, kitchen, dining area, and other things you may consider important. Some of these things are paramount while you can do without some.

For instance, you may not need a garage as a carport on another part of the property can be used. Another thing you can decide to do without is the hallway. This does not mean you should strike them out. It only means they can be erased from the eventual design.

The Size of Every Part

Some people who hire architects to design a custom-made plan go back and forth with their architects for different reasons. This period spent going back and forth amounts to billable hours that will need to be paid for. As a result, some of them end up spending more than they planned on the initial consultation. You need to do all you can to prevent or reduce the chances of this happening.

One thing you can do is decide how big or small you want parts of the house to be. You need to understand your personal preferences to arrive at something you would love. For instance, some people cannot just deal with a small kitchen. They need all the space they can get there. The whole point here is understanding exactly what you want and making sure that the eventual design aligns with them.

Style and Floors

The 30×40 plan is more about size and not style as explained earlier. So, you need to decide what style you want. You should also know that some architectural styles will look better with 30×40 plans than others. Options such as cottages, cabins, and bungalows fall into this category. Just make sure what you choose also suits your needs.

You also need to decide the number of floors. We strongly advise people that want so many features and want them large to consider more than 1 story. This is because the upper portion will provide more space.

30×40 House Floor Plans

Usually, the architectural style you choose to implement is supposed to determine your floor plan. However, there are times this is not the case. This is especially the case when using the common floor plans associated with the style will not serve a functional purpose.

So, you have to understand what you want and the role the available space may play. Some of the things to consider when choosing a floor plan include:

Adequate Ventilation

Take note of your access to fresh air when choosing a floor plan. Make sure what you end up with does not inhibit your access to fresh air. More often than not, the open concept option is best in this regard. This is because of the absence of interior walls that keep air out.

This may however not be the best option for cold regions. This is because the expense of keeping the place warm is more. So, your geographical location should also influence what you choose.


Certain floor plans make it easier to access other parts while some make you think twice before taking a step. So, you should also consider this when making your choice.

Natural Light

We advise that you do not take natural light for granted as it can play an important role in your home. First, it makes the place look better. Secondly, natural light offers more health benefits than many of us know. So, the floor plan chosen should help make interior access to natural light possible.

30×40 Barndominium Floor Plans

A Barndominium is one of those amazing styles that can fit into a 30×40 house plan. If you decide to use this design, you should know that the floor plan is usually something that allows easy access. This is why the open concept is the go-to option for people that make use of this design.

We also advise that you do the same considering the many benefits it offers. However, you should also be aware of what some may consider a disadvantage. For instance, complete privacy may be hard to achieve with this option. If however you’re not into that level of privacy, then know that socializing is quite easy with this floor plan. So, you should certainly think seriously about it if you think socialization would mean a lot to the occupants.
