  1. Implement a Side Return Extension to Your Kitchen

If your goal is to create a bigger kitchen and/or dining area, you should keep in mind that the side returns are probably not used properly in your home and if not, they do not add value to your property estimate. However, building a single extension into it can be an affordable idea that will completely transform the most used area in your residence.

This idea is usually implemented in kitchens and it will be able to turn a smaller kitchen into an open-plan, larger area. Additionally, it can provide you with a dining area that is facing the garden, hence, creating a pleasant atmosphere. You most likely won’t need a construction permit for it and it can cost up to $20.000 dollars. The price will, of course, depend on how larger the project is.

  1. Your Porch Can Become a Living Space

One of the cheapest things that you can do is to add a porch and transform it into a living space. Now, you’ll need to wisely think about the design. It needs to be designed in a way that will fit the original architecture of your house, as well as the size and proportion of it.

When creating a construction plan for your enclosed porch, you should consider the amount of natural light that will flow through the doors and windows, as well as how you’ll connect the place with the rest of your home. The price will depend on the size of the porch and the materials you choose to use.

  1. Your Garage Can Be Converted

Besides providing you with additional space, it will also add more value to your entire estate. By choosing to convert your garage, you won’t lose any yard space as well! Hence, if you have a double garage or if you do not own a car, you should definitely consider converting it into a room.

It is relatively cheap to do so, in fact, it is the cheapest option on this list. The renovation of the walls and floors, as well as the removal of the garage door can cost you up to 5.000 dollars. But, besides that, you’ll probably spend most of your budget on purchasing new furniture for the new area.

  1. Opt For Raising a Conservatory

If you choose to add a simple conservatory – whether it has a traditional or modern look – is a cheap extension that will provide you with the perfect dining area during the entire year. Now, it might be best for you to choose a professional design and build company, especially since it is difficult to install everything on your own.

This option can cost you anywhere from $10.000 to $20.000 dollars, however, you should know that it will be an exceptional addition to your house, one that will boost your property value by up to 10%.

  1. Construct a Garden Shed For More Storage Space

If you do not need more space for living, but instead room for storing items that you do not need, you should consider building a garden shed in your yard. This option will not only allow you to store your seasonal gardening tools but, other items as well. This includes the things that have been cluttering your garage or basement.

The price will depend on the size you want, the materials you choose to purchase, the doors and windows, whether or not it will have insulation, as well as the finishes on the exterior and interior walls. If you want to go for the cheapest option, you should opt for a modular kit, but, expect the prices to go anywhere from $1.500 to $25.000.

  1. Add a Room Above Your Garage

This option is only viable if you have a garage that has foundations that can take a heavy load. If so, you can choose to build an additional room on top of it, which is an option that is quite affordable. Plus, you won’t need to use any of your backyard space for adding a new room.

For this, you’ll definitely need to consult an engineer about whether or not the structure can take it, and you’ll probably need to hire an architect, as well as a good construction company that will ensure that the new space accompanies your house inside and out. The price will most likely vary from project to project, but, expect to pay approximately $20.000 for it.

Bonus Tip – Do Not Forget The Permits

Whatever you choose to add to the inside of your house probably won’t need a building permit, however, if you are planning on building something outside your house or on top of it, you should know that you’ll most likely need to obtain a permit for the project. Of course, this will vary from state to state, but, it is better to check and obtain it if needed than to be sorry later on when you must pay fees.


As you can see, there is actually a lot of extension types that you can choose in order to add more space to your residence. So, now that you know what you can opt for, you should not lose any more time. Instead, determine which extension from above might fit your needs and house, and search for a company that’ll help you make your dream of having a larger house true!
