Can You Build a House with Interlocking Concrete Blocks?

Interlocking Concrete Blocks are one of the most convenient building options available on the market. But what exactly can be built with them? Are they just suitable for retaining walls or a temporary structure? Or can you make anything with them, including houses?

Why are houses usually made of brick?

Why are houses usually made of brick?

As you probably know already, a lot of the houses, if not all, are made from brick and mortar. But why exactly is this the case? To put it simply, bricks are a reliable, tried and tested method with a few benefits that have seen it become the go-to material for many exteriors of a house.

Firstly, they’re durable, they remain reliable in any kind of weather, which is especially handy for places like the UK, where weather can get unpredictable, especially in recent times. As a result of their durability, they allow houses to stand tall for countless decades.

Bricks also have an especially helpful interaction with heat. They can absorb heat during the day, and release it slowly in the evening, allowing the home to stay warmer in the winter and cooler in hot summer nights, contributing to better energy bills. Aside from warmth, they also help to keep sound from outside, from coming in. (Though they are not soundproof by any means).

Fire safety, a key factor in building regulations, is also covered by the humble brick, as they do not burn at all, unlike wood or other materials. 

From an aesthetic angle, bricks hold a variety of colours, textures and styles, giving you the freedom to stand out from the houses in your area if you choose, without compromising the traditional aesthetic provided by the brick.

Bricks are made of clay, a relatively inexpensive material that is abundant, and recyclable. This makes them a good option for somebody looking for sustainable options that aren’t overly expensive.  

Can you build a house with Interlocking Concrete Blocks?

Where to find stackable interlocking concrete blocks

In a technical sense, it is possible to use Interlocking Concrete Blocks to build a house, but this is not a guarantee. This is because any new build must be approved with planning permission. If your local planning authority isn’t convinced with the materials you intend to use for the build, for whatever reason, then you can not legally use them to build. 

Whilst considering planning permission, your build also has to comply with building regulations in the UK. If your build isn’t up to par with things like structural safety, insulation, accessibility, and much more, your build will not be compliant. This can result in delay or more significant outcomes depending on the situation. 

This is why it is absolutely critical to seek the guidance of a structural engineer. They will able to provide the experience and understanding needed to bring your build to life with the materials and plans you provide them. That being said, if your ambitions for the build aren’t realistic, they will work with you to make them compliant to both planning authorities and building regulations. 

Why would you want to build with Interlocking Concrete Blocks?

Constructing with Interlocking Concrete Blocks can be a smooth process due to their simplicity. They only require accurate placement in order to create a strong and lasting hold via their studs and recesses connecting with each other. 

Like bricks, Interlocking Concrete Blocks hold similar fire resistant, sound resistant, and thermal benefits. From an aesthetic standpoint, concrete presents a uniform look that is open to customisation, making it possible for you to have unique designs or looks that brick houses can’t get. 


Furthermore concrete is a dense, durable and strong material, providing a solid foundation and protection. In some cases it may seem perfect. But are there any reasons that it may not be feasible to use for a house?

Why won’t someone build with Interlocking Concrete Blocks?

Interlocking Concrete Blocks can stack upon each other, but not forever. Regular two storey homes in the UK normally come in at a height of 20-25 feet, single storey homes can be around half of this height. 

In most cases (with possible exceptions) Interlocking Concrete Blocks can safely stack up to roughly 9 feet. Though this may vary between Interlocking Concrete Block providers and what they offer.

Another consideration is transportation and installation. A significant amount of blocks must be transported by specific heavy-duty vehicles, and then installed using machinery capable of lifting and placing them safely. Although this could require less labourers on site, it may also mean a higher total cost as a result of the transportation, as well as rent for the machinery used for the install.

To summarise, Interlocking Concrete Blocks may have the potential to be used as part of a home or its other elements, though this is subject to the specifics of the build and pending approval. For confirmation, you should consulate with a structural engineer with the plans you want to execute, and make enquiries with trusted Interlocking Concrete Block Providers like PPC Concrete Products. 

The benefits of a house made with Interlocking Concrete Blocks

So if planning permission were granted, and building regulations were followed, what are the benefits you can expect from a home made from Interlocking Concrete Blocks? Aside from the points we mentioned earlier, you can expect:

A relatively quick construction phase

Designed to fit harmoniously with each other, and negating the need for mortar, Interlocking Concrete Blocks can experience a quicker construction phase. Though this depends on the block size and equipment handy. This is helpful for the UK as weather can significantly affect the speed of a build. 

Cost-effective

It can be argued that the blocks are more expensive than bricks initially, however depending on the build, the quicker construction time provided, in addition to requiring fewer labourers can result in a lower overall cost. (Though transportation and hiring machinery for installation can be a factor).

Longevity + sustainability = the best results

Inherently, concrete is a tough material, proving strong and durable with an effective resistance to weathering, fire, and some impacts. This allows them to last longer over time, and can result in fewer maintenance jobs required. 

Depending on your provider, you may find the option of recycled concrete blocks, still as effective as their counterparts, but sourced more responsibly. This helps to reduce the environmental impact associated with construction, a great option for eco-friendly homeowners.
