Choosing and Preparing a Site for Construction in Ireland

Anyone who has ever considered building a structure knows that everything doesn’t start with pouring concrete for the foundation—it all begins with choosing the right site. In the context of Ireland’s unique landscape and climate, selecting the right plot is perhaps the most critical step. However, one must also factor in infrastructure, geology, environmental restrictions, and many other aspects.

In this article, we’ll thoroughly examine every factor you need to consider when choosing a site. We’ll highlight the key criteria to look out for, discuss potential pitfalls at each stage, and as a bonus, offer recommendations on preparing the site for construction.

1. The Importance of Selecting the Right Site

There’s no exaggeration here: purchasing a site for construction is the most crucial stage of any project. Even if a plot is in an area with excellent infrastructure, a poor choice in location can result in significant extra costs and lengthy delays.

What to Consider When Buying a Plot in Ireland

Location and Proximity to Transport:
In Ireland, where development outside of the city centres is quite varied, proximity to main roads, transport links, and key infrastructure significantly affects both the price and the future usability of the property. For instance, houses built closer to urban areas typically command a higher price than similar properties in more remote locations.

Availability of Utilities:
Technical services such as water, sewerage, electricity, and even gas play a direct role in determining construction costs and the convenience of future use. Take, for example, sewerage connections—the cost of connecting to the mains is much lower than building your own septic system, not to mention the hassle of maintenance, pumping, and waste disposal. This can save both time and money in the long run.

Geological Characteristics:
This is a topic for a separate article, which we will explore in greater detail following consultations with geologists. Here, factors like soil type, groundwater levels, slope of the land, and drainage conditions are all crucial. Each of these parameters directly influences the type of foundation required and its associated costs.

Assessing all these factors, or more precisely, their combined effect, can help you avoid numerous problems in the future and ensure a comfortable, safe, and energy-efficient building.

2. Key Criteria for Selecting a Site

2.1 Location and Transport Accessibility

The site’s location is the most important factor when evaluating land value. Even a less-than-ideal plot in central Dublin can be more expensive than a perfect plot in a desolate area outside the city. Let’s consider three key aspects from an infrastructure perspective:

Proximity to Major Roads:
Being near major junctions reduces transport costs in the future and allows residents to get home quickly and comfortably. It also cuts down on the delivery costs for construction materials.
Access to Public Transport:
This is particularly important for residential projects, as well as facilities like hotels. For large residential developments, if a public transport line runs nearby, it may even be possible to negotiate with local authorities or transport companies to add an extra stop.
Local Infrastructure:
The presence of shops, schools, medical facilities, and other social amenities nearby enhances the attractiveness of the site for potential residents and, correspondingly, its market value.

When choosing a site, pay attention to:

Data provided by local councils (such as infrastructure maps and approved development plans).
Feedback from local residents (simply take a walk around the area and ask locals what’s missing or what they dislike; in larger cities, it’s important to know about noise levels and road accessibility during peak hours).

2.2 Availability of Utilities

Access to engineering networks is usually a given in urban areas but can be a significant additional expense in remote regions.

Water Supply and Sewerage:
Before purchasing, you can enquire with the local Irish Water office about the possibility of connection at the address. If the response is positive, you will need detailed drawings and calculations to secure the necessary approvals. Otherwise, you may have to factor in the cost of installing on-site water collection and storage systems, as well as constructing a septic tank.
Electricity:
Electricity is widely available – nearly 99% of Ireland is connected to the grid. You can check connection options and costs with local authorities. Alternatively, you might consider independent power generation systems such as wind turbines, which, thanks to Ireland’s green initiatives, might even offer some financial return on your investment.
Gas:
Gas connections are rare even in urban areas, so it’s advisable to carefully consider your need for gas and, if possible, avoid relying on it.
Internet:
Modern technologies mean you no longer need to run long cables to avoid signal drop-off. Satellite internet services (like Starlink) or radio internet can provide reliable connectivity. This isn’t an absolute necessity unless you plan to reside on the site rather than just develop it.

2.3 Geological Characteristics and Soil Conditions

The geological makeup of your plot influences many factors:

Soil Type:
Whether the soil is rocky, sandy, or clayey, modern construction technologies can build stable structures on almost any type. However, each soil type requires a specific approach, which can significantly affect foundation costs. For example, on clayey soil, you’ll need proper drainage to prevent excessive moisture accumulation around the foundation.
Groundwater Level:
A high groundwater level can cause issues with basements or require extra drainage measures. In some cases, a high water table might even allow you to create an attractive water feature, though this comes with its own set of challenges.
Land Topography:
The slope of the land, the presence of inclines or depressions, all influence the type of foundation and drainage measures needed. A flat area is generally preferable, but with the right architectural vision and sufficient budget, even a sloping site can be turned into a striking architectural feature.

Conducting a geotechnical survey is an essential step that cannot be overlooked. It helps you identify potential issues ahead of time and calculate the acceptable loads and necessary measures, thereby avoiding unforeseen expenses and delays during construction.

3. Preparing the Site for Construction

3.1 Legal Due Diligence

Always verify all legal aspects:

Title and Ownership:
Ensure that the land is fully in your name, with no disputes or encumbrances that could lead to legal action. Court orders might even halt construction if ownership is questioned.
Zoning and Local Development Plans:
Check whether your intended project falls within the approved types of development for the area. This will help avoid issues with local authorities and secure Planning Permission without unnecessary delays.

3.2 Preparing the Infrastructure

Clearing the Land:
Depending on the site’s condition, you may need to clear vegetation, demolish old structures, and remove waste.
Installing Temporary Utilities:
If the site is far from major networks, organise temporary electricity and water supplies to facilitate the construction phase.
Drainage and Earthworks:
If the plot is sloping or has groundwater issues, design a drainage system to prevent flooding or soil liquefaction.

3.3 Professional Consultations

Geotechnical Engineers:
Hire a team equipped with the right technology to carry out a detailed analysis of the soil, measure groundwater levels, and determine the optimal foundation type.
Architects:
Opt for local professionals familiar with Irish standards and regulations. They can help assess the site’s suitability for your project.
Engineering Consultants for Utilities:
These specialists will conduct the necessary calculations for connecting to local utility networks and explain the requirements your building must meet.

Consulting with experts early on will help you identify potential issues, reduce risks, and ultimately save time and money during the construction process.

4. Practical Recommendations for Selecting a Site

4.1 Conduct a Thorough Analysis

Before making your final decision:

Visit the site at different times of day and in various weather conditions to gauge its true state.
Study local infrastructure maps and development plans, and speak with local authorities to understand the area’s characteristics.
Compare several options based on key criteria such as transport accessibility, utility availability, and geological conditions.

4.2 Documentation and Expert Evaluation

Quality documentation is key:

Commission geotechnical surveys to determine soil characteristics.
Obtain an extract from the land registry to ensure there are no encumbrances.
Consult a local architect to evaluate whether the site suits your project’s needs.

4.3 Planning Future Utility Connections

Pay special attention to how the site will be connected to essential utilities:

Contact Irish Water to inquire about connection conditions for water supply and sewerage.
Find out what electricity networks are available and the terms of connection.
If you plan to use gas or require high-speed internet, check the technical capabilities in the area.
