Garden Room Costs in Ireland: 2025 Pricing Guide- Summerhouse24.ie

A garden room is a versatile addition that can be used for various purposes, from a home office to a cozy retreat for hobbies, relaxation, and entertainment, or even as a playroom for your children. Unlike traditional sheds, garden rooms are designed with aesthetics and functionality in mind and often feature large windows, insulation, and high-quality finishes. They provide an excellent way to extend your living space without the need for extensive renovations to your home, making them a cost-effective way to raise the value of your property.

In recent years, the popularity of garden rooms has surged in Ireland. The rise in remote working has been a major contributing factor to this trend, as many people look for dedicated and quiet workspaces away from the main house. Additionally, as more people seek ways to expand their homes for adult children, garden rooms have become an appealing option for Irish homeowners.

What factors influence garden room cost?

In Ireland, there are several key factors that can significantly impact the overall cost of building a garden room.

1. Size variations

The size of your garden room is one of the most influential factors in determining its cost. Larger spaces naturally require more materials and labour, driving up the price. The good news is that companies like Summerhouse24 offer options that suit every budget and start from around €4,500 for a basic structure, but the price range can vary significantly, going up all the way to €50,000 at the higher end for the biggest garden rooms.

2. Material choices

It goes without saying that the materials you choose to build with will significantly impact your garden room cost.¹ Concrete and brick garden rooms cost more than timber ones and certain features, like glass sliding doors for example, can also drive up the costs. When choosing your materials, it’s a good idea to phone around and get custom quotes so you can make an informed decision and strike the delicate balance between durability, appearance, and budget.

3. Design complexity

If your budget is tight, keep your design as simple as possible. Straightforward square or rectangular structures are generally more affordable, while custom shapes and bespoke features often come with a higher price tag.

4. Site preparation

Site preparation refers to getting the area where you wish to build primed for the structure to sit securely. Factors like uneven terrain, poor soil quality, or the need for extensive landscaping can add to the overall expense. The type of foundation required is also crucial – options range from concrete bases to ground screws, each with its own cost implications to consider.

5. Irish planning regulations

In Ireland, you can build a garden room up to 25m² without planning permission, so long as you don’t plan to live in it or operate a place of business from it. However, if your project exceeds this size or doesn’t meet the exemption criteria, you may need to apply for planning permission, which can add to your costs. Here is a ballpark idea of what you’ll pay, but it’s always best to consult with your local planning authority before undertaking any building.

€65 for the planning permission application.²
€140 or more for the newspaper notices.
€126 for the site maps.³
€350 for a building compliance certificate (if needed). ⁴

6. Local building considerations

If you live in an area with strict building codes or conservation rules⁵, you might need to use specific materials or adhere to certain design guidelines, potentially increasing costs. It’s so important to familiarise yourself with zoning regulations or local development plans so you can account for these in your budgeting.

** It’s worth noting that typically building costs in the city will be higher than in the country and the costs do vary between different companies. Phoning around and getting customised quotes for your specific plans will give you a far better idea of the end cost, allowing you to budget carefully.

Breakdown of garden room costs

Let’s break down the various aspects of garden room costs to give you a clearer picture.

Basic garden room costs

These are the basics that you will be paying for:

The garden room itself (whether that’s a prefabricated kit or the materials)
Delivery charges – these can run into hundreds depending on where you live. We at Summerhouse24 offer free delivery, so it’s wise to shop around.
The foundation (you will need to get a DIY foundation kit or hire a company to lay one)
Site preparation
Labour costs
Refuse removal after the build
Plumbing, electricity, insulation
Wood protection since this is an outdoor structure
Indoor finishes to the wood (paint or wood stains)
The furniture you plan to decorate with

Brick garden room costs

When it comes to creating a lasting outdoor space, brick garden rooms are a great choice and provide a sense of permanence that can significantly boost your property’s value, however the cost of building a brick garden room can be hefty.

In Ireland, brick garden room costs can vary widely, influenced by several factors:

The design
Material quality
Site preparation requirements
Regional labor costs (with Dublin typically commanding higher rates)

Here’s the typical price range:

Price per m²	Approx €160 to €180
Price per brick	Approx €1.50 to €2.50
Price per day	Approx €250 to €350

Average cost ranges

For a timber framed garden room from Summerhouse24 you can expect these price ranges:

Size	Price range
Small: up to 15m²	Approx €4,000 to €15,000
Medium: up to 25m²	Approx €15,000 to €20,000
Large: bigger than 25m²	Approx €14,000 to €21,000

It’s far more cost effective to buy a garden room kit, because you know all the costs involved upfront. When you build on site costs increase exponentially and depending on the size of your room, can hit an excess of €50,000.

Price per square meter

For a basic garden room, you can expect to pay around €850-€1,500 per square metre for a fully fitted structure. This means a compact 10-12m² garden room might start at approximately €12,000. However, prices can vary significantly based on design, materials, and features, so you will want to shop around for the best prices.

Cost comparison with traditional extensions

The Royal Institute of Architects in Ireland published a guide in 2019⁶ that put the range per square metre for a house extension somewhere between €1,900 to €3,400. This is more than double the cost of a garden room per square metre and also would be higher now 5 years later.

Additional features and their impact on price

The cost of a garden room with a shower, toilet, or bathroom can significantly add to your final bill. Here’s what you can expect to pay for these features.

Garden room with toilet cost (including a hand basin)	You can expect to pay around €3,100
Bathroom installation expenses	To partition off the bathroom for privacy you can expect to pay around €1,900
Cost of a garden room with bathroom (fully kitted out)	For a full shower room (toilet, shower and hand basin) you can expect to pay around €4,500
Electrical work	Connecting to the electrical network costs approx €3,486
Insulation	From approx €2,000 upwards for full door, window, floor and roof insulation
Plumbing expenses	Connecting to the water supply is a €2,272 flat fee Connecting waste removal to the main house is approx €1,350

Budget friendly options to help lower your garden room cost

When it comes to building your dream garden room, costs can quickly add up. While you definitely don’t want to skimp on quality, there are some frugal tactics you can use to keep costs down.

DIY vs. professional installation

One of the biggest decisions you’ll face is whether to tackle the project yourself or hire professionals. While DIY can save you money on labour costs, it’s important to honestly assess your skills and available time.

If you’re handy and have experience with construction projects, a DIY approach could significantly reduce your expenses. Some companies in Ireland, like Summerhouse24, offer self-build kits that can help you get started. These kits come with detailed instructions, all the parts, and even pre-drilled holes to make it easier for you.

Cost-saving tips

Here are some practical ways to keep costs down:

Focus on essential features and skip the luxury add-ons for now. These can be added slowly over time once the basic structure is in place.
Compare prices from different suppliers to find the best deals on materials, labour, and design.
A straightforward, rectangular structure is generally more affordable than more complex designs.
Pre-designed garden rooms can be more cost-effective than fully bespoke options.

Seasonal considerations for building

Timing your garden room project strategically can lead to savings:

Generally, the winter months are quieter for garden businesses and you might find some great discounts (here’s looking at you Black Friday!).
Spring and early summer are typically the busiest, potentially leading to higher prices due to increased demand.

**Remember, while it’s important to be cost-conscious, don’t compromise on quality for essential elements like insulation and weather-proofing. A well-built garden room is an investment that can add value to your home and provide enjoyment for years to come.

Return on investment

A garden room can be a savvy investment if you are strategic about its use. By carefully considering how you utilise this versatile area, you can potentially offset the initial garden room cost and even generate long-term financial advantages.

Property value increase

In the Irish property market, potential buyers are increasingly attracted to homes with additional, functional outdoor spaces. In fact, a high-quality garden room can increase property value by approximately 5-10%, depending on the design, quality, and integration with your existing property.⁷

Home office potential

By creating a dedicated workspace in a garden room you could:

Potentially claim tax deductions for home office expenses
Increase productivity by separating work and home environments
Reduce commuting costs and time
Improve your work-life balance

Rental opportunities

Provided you secure the correct planning permission, your garden room could become a source of additional income from:

Short-term holiday rentals
Home office rental for freelancers
Potential Airbnb space
Studio for creative professionals
Gym space for a personal trainer
Child care space

Choosing the right garden room

Choosing the right garden room and making sure it meets your needs and enhances your property is not something that should be rushed. With so many options available, it’s important to ask the right questions and understand what to look for when working with contractors. Here are some key considerations to guide you through the process.

Questions to ask contractors

When interviewing potential contractors for your garden room project, asking the right questions can help you gauge their expertise and reliability. Consider these:

What is your experience with garden room construction?

Understanding their background can give you confidence in their ability to deliver quality work.

Can you provide references or examples of previous projects?

This will help you assess their style and craftsmanship.

What is included in your quote?

Ensure you have a clear understanding of what materials, labor, and additional costs are covered.

How long will the project take?

Knowing the timeline helps you plan accordingly and set realistic expectations.

Do you offer a warranty or guarantee on your work?

A solid warranty can provide peace of mind regarding the quality of construction.

Getting accurate quotes

This is essential for budgeting your garden room project effectively. Here are some tips to ensure you receive reliable estimates:

Request detailed quotes from multiple contractors so you can compare prices and services offered.
Ensure quotes include all aspects of the project including materials, labor, site preparation, and any additional features.
Be clear about your specifications and provide contractors with detailed information about your desired design and materials so they can give more accurate estimates.
Inquire about any possible extra charges or hidden costs that may arise during construction.

What to look for in garden room design

The design of your garden room should reflect both your personal style and functional needs. Here are key elements to consider:

Ensure the layout accommodates your intended use, whether it’s an office, studio, or recreational space.
Incorporate windows to maximise daylight and create an inviting atmosphere.
Choose a design that complements your home’s architecture and enhances the overall look of your garden.
Consider eco-friendly materials and energy-efficient features that can reduce the environmental impact and lower your utility costs over time.

Conclusion

Investing in a garden room is not only a fun project, but it can also be financially rewarding when you do it right. Taking the time to research and plan properly so you make an informed decision will result in a beautiful addition to your home that meets your needs and fits within your budget.
