Traditional Brick and Block vs Timber Frame Construction
When it comes to purchasing a home, building a home or adding additional space, construction is an important factor to consider. From how long it takes to create, to how future-proof it is, the choice between Traditional Brick and Block and Timber Frame construction can make a difference to the start and overall finish of a project. In this article, we’ll be explaining all the things you need to know about the differences, benefits and disadvantages of these types of construction.
What is Traditional Brick and Block construction?
‘Approximately 70% of new self-builds use brick and block.’
Also referred to as modern masonry, the Traditional Brick and Block construction method includes two sets of block walls creating a cavity between the two. The outer wall uses facing bricks, giving the traditional brick look and the inner wall uses larger concrete blocks. The cavity between the two provides a space for insulation. A building using this construction method will be built to the first floor with Brick and Block, followed by the internal and load-bearing walls. Once this has been completed, timber joists or a concrete floor will be added and then the build will continue.
What is Timber Frame construction?
‘Timber frame accounts for approximately 22% of self-builds.’
Timber Frame or Post-and-Beam is another mainstream construction choice. The structural frame from timber studs, rails and structural sheathing board, transfers the load-bearing weight onto the foundations. In the UK, Platform Frame is the most common type of Timber Frame construction. Similar to Brick and Block construction, levels are built one at a time before additional floors are put on top.
What is the difference between Traditional Brick and Block and Timber Frame construction?
Although Brick can be used for an aesthetical choice surrounding a Timber Frame, there are differences in material delivery and the execution of the design. When choosing Brick and Block frames, materials are delivered to the site and the construction is created from the detailed drawings. With Timber Frame construction, designs are sent to workshops that cut timber to the precise measurements. These sections are then delivered to the site to form the final construction.
What are the benefits of Timber frame construction?
‘The national house building council (NHBC) estimate that using timber frame can save up to 3 months off your build time.’
Environmental Footprint
If materials are responsibly sourced and a replanting initiative is in place, the carbon footprint of a new build can be reduced.
Energy Bills
Room temperatures are more easily adjustable and can be adjusted at quicker rates. This often suits homes that may be vacant for periods of time so heating bills can be reduced.
Rot, Fire and Insects
Modern design and advancements in treatments allow designs that have suitable ventilation to make Timber frames rot, fire and insect resistant.
Initial cost vs construction time
A starting cost might be higher than other frame constructions, but the labour time is less often making Timber frames more financially beneficial.
What are the benefits of Traditional Brick and Block construction?
‘The main advantage of brick and block construction is its flexibility.’
Unique Designs
Brick and Block construction is the most traditional style but there is a wide variety of styles that can make homes unique and modern.
Durability and Longevity
As Brick and Block is incredibly durable its longevity helps to offset its initial carbon footprint.
Insulation and Sound Proofing Properties
Great for urban areas and lowering energy bills.
Talented Makers and Designers
Due to the traditional nature, there are many skilled professionals in the designing and creation of Brick and Block frames.
Mortgages
It has been noted that mortgage providers are favourable to Brick and Block constructions.
What are the disadvantages of Timber frame construction?
‘Timber frame structures may not achieve the same level of sound insulation as concrete or masonry as they are not as dense.’
Precise Foundations
As the frames are cut exact away from the site, foundations have to be precise in order to accommodate without room for error.
Stereotyping
There is an unpopular (and unfounded) opinion that people just don’t like Timber frames which can lead to them looking unpopular in comparison to other construction types.
Internal Fixings
Although there have been great advancements in fixings available for sheet walls, many people still believe that a timber frame means there is difficulty later on when wanting to hang on these walls.
The Mortgage Myth
It is a myth that Timber frame buildings are more difficult to get a mortgage on. After decades of people building using this method, the factors needed to get a mortgage on this type of construction are inclusive of the design, making it easier to be approved.
What are the disadvantages of Traditional Brick and Block construction?
‘Buildings take longer to become weather tight and work to the inside of the building cannot commence until it is.’
Lower resistance to movement
Movement from the foundations can cause cracking. This is often because of the thermal expansion of the walls.
Larger Foundations
Due to the material type, Brick and Block construction require larger foundations in comparison to other types of construction which increase labour, time and material costs.
Moisture Ingress
Also referred to as penetrating damp, water ingress can occur in Brick and Block buildings when water from outdoors makes its way through the walls to the interior of the space.
There are both advantages and disadvantages to any type of construction. Each type allows a different type of design, style, build time and cost amongst other factors. For any building project, speaking to an experienced labourer or designer can help establish what the best option of construction is for your project. They will be able to understand the desires and requirements of a new project and be able to advise the best type of construction.
Frequently asked questions:
Is Timber more environmentally friendly?
If Timber is sourced from responsible location that is involved in renewable and sustainable practices, Timber frame construction can be an environmentally friendly option. In comparison to Brick and Block the longevity of the build is where the environmental costs can be weighed.
Can you still get a mortgage on a Timber frame construction?
Yes. Nowadays, the factors that used to cause concern for mortgage brokers can be factored into the design of a build. This makes it easier to get approved for a mortgage.
Does a Timber frame increase heating costs?
A Timber frame actually reduces heating costs as it provides high levels of thermal insulation. In combination with sustainable and efficient insulation, a dramatic difference can be made to the overall cost of heating a home.
Do Timber frames cause less acoustic insulation?
If a Timber frame isn’t combined with sufficient insulation it can be less soundproof. However, due to the nature of this construction, they are often more solidly insulated than other construction types.
Which construction offers more fire protection?
Many believe that because Timber frames contain more wood, they are less fire-resistant. All inner construction is treated and then a barrier of brick and plaster surround this which increases fire resistance. All construction types contain timber elements and are protected in this way.
