A double garage is not only a practical addition to any home, providing ample space for vehicles and storage, but it can also significantly enhance the property’s value, especiall if converted into more usable space such as a gym room, home office, bar, or garden room.

For homeowners across the UK contemplating this addition, one pertinent question often arises: How much value do double garages add to a house?

In this comprehensive article, we will delve into this topic, exploring the impact a double garage can have on property value and why the material and construction method play a crucial role in determining the return on investment (ROI).

The Impact on Property Value

The addition of a double garage can be a game-changer in terms of property value, especially in areas where parking space is at a premium. Real estate experts agree that a double garage can add anywhere from 5% to 10% to the value of a property, depending on the location and the overall property market conditions. This percentage translates to a substantial amount, particularly in regions with higher property values.

These values can significantly rise again, if all or part of the double garage is converted for leasure use.

It’s important to note that the added value does not solely depend on the presence of a double garage; its condition, functionality, and aesthetic appeal also play vital roles. A well-maintained, secure, and aesthetically pleasing garage is more likely to contribute positively to the property’s value.

Comparing Materials: Brick, Block, Timber, and Concrete

When it comes to constructing a double garage, there are various materials to consider: brick, block, timber, and concrete. Each material has its own set of advantages and disadvantages, influencing the overall cost of the project and the potential ROI.

  1. Brick Garages: Brick is a popular choice for its durability and aesthetic appeal, often matching the existing property’s exterior. However, it is also one of the more expensive options, both in terms of material and labour costs.
  2. Block Garages: Concrete blocks provide a more cost-effective solution than brick, while still offering durability. They can be finished with rendering or cladding to enhance their appearance, though this adds to the overall cost.
  3. Timber Garages: Timber offers a natural and attractive aesthetic, and with proper maintenance, it can be a durable option. However, it requires regular upkeep to prevent rot and pest infestation, contributing to higher long-term costs.
  4. Concrete Sectional Garages: Pre-fabricated concrete panels offer a quick and economical construction option. While they may lack the aesthetic appeal of brick, they provide a durable and low-maintenance solution.

Evaluating Cost-Effectiveness and ROI

When determining the most cost-effective option for adding a double garage, it is crucial to consider both the initial construction costs and the long-term maintenance expenses. Brick and block garages, while potentially offering higher aesthetic value, come with substantial initial costs and ongoing maintenance requirements. Timber garages provide a middle ground, but maintenance costs can quickly add up.

Concrete sectional garages stand out as the most economical option in terms of construction costs. The pre-fabricated panels are quick to install, significantly reducing labour costs. Additionally, their durability and low maintenance requirements contribute to lower long-term expenses.

In terms of ROI, all types of double garages—brick, block, timber, and concrete—have the potential to add similar value to a property, ranging from 5% to 10% or even more. However, the lower construction and maintenance costs associated with concrete sectional garages result in a more cost-effective investment, maximising the ROI.


Adding a double garage to your property can be a wise investment, enhancing both the functionality and value of your home. While brick, block, timber, and concrete garages all have the potential to add similar value to a property, it is the cost-effectiveness of the construction and maintenance that differentiates them in terms of ROI.

Concrete sectional garages emerge as the most economical option, providing a practical and durable solution without the high initial costs and ongoing maintenance associated with other materials. By choosing a concrete sectional garage, homeowners can maximise their return on investment, ensuring that the addition of a double garage is not only a valuable asset but also a cost-effective enhancement to their property.
