Self-Building a Timber Garage or Carport: A Complete Guide for Irish Homeowners
31.12.2025

Thinking about adding a timber garage or carport to your property? Whether you need secure storage for your vehicles or extra space for a workshop, a wooden garage offers a cost-effective and attractive solution. This guide covers everything you need to know about timber garages and carport kits, from pricing and planning permission to installation options.
Timber garage and carport options available in Ireland
When considering a timber garage for your Irish property, you’ll find several options to suit different needs:
Single garages typically range from 16-21m², perfect for housing one vehicle plus storage. Double garages offer more spacious structures between 24-37m², accommodating two vehicles with additional workspace for hobbies or tools.
For more flexibility, garage-carport combinations provide both enclosed storage and covered parking in one structure. If you simply need protection from the elements without full enclosure, standalone carports offer an economical solution.
Our wooden garage range features Nordic spruce construction with different wall thickness options to suit your specific requirements and budget.
Price expectations for timber garage kits
The cost of your timber garage will depend on size, wall thickness, and specifications. Current market research shows these price ranges:
Single Garages:
- 44mm wall thickness: €6,250-€6,600 for approximately 16m²
- 70mm wall thickness: €10,780-€11,050 for approximately 21m²
- Price per square metre: €390-€527
Double Garages:
- 44mm wall thickness: €7,430-€9,350 for 24-31m²
- 70mm wall thickness: €11,430-€15,150 for 24-37m²
- Price per square metre: €301-€409
Garage-Carport Combinations:
- Starting from €7,880 for 17m² (44mm walls)
- Premium models from €13,800 for 21m² (70mm walls)
Standalone Carports:
- Basic wooden carports: €4,070-€5,170 for 18-32m²
- Carport with storage shed (like our Arthur model): From €8,010
These figures represent a significant saving compared to traditional masonry garages, which can cost upwards of €1,500 per square metre when built in brick.
Specifications and materials
Understanding the specifications helps you choose the right option for your needs:
Wall thickness is most commonly available in 44mm and 70mm options, with thicker walls offering better insulation and durability. The high-quality Nordic spruce used in our structures is known for its strength and resistance to warping.
The interlocking timber system provides structural integrity without requiring extensive framing, making assembly more straightforward. Roofing typically includes felt shingles, with premium roof shingles available for better weatherproofing and aesthetics.
Door options range from traditional hinged doors to roller or up-and-over garage doors depending on your preference and budget.
The 70mm wall options command a 40-70% premium over 44mm models but offer enhanced insulation and durability which is an important consideration for Irish weather conditions.
Planning permission for timber garages in Ireland
Before ordering your timber garage kit, it’s essential to understand the planning requirements:
In Ireland, most small garden structures under 25m² may be exempt from planning permission if they meet specific criteria. Structures must typically be located to the rear of the property and not reduce the open space behind the house by more than 50%.
Height restrictions apply, generally with a maximum of 3-4 metres depending on roof type. For detailed information on whether your planned garage requires permission, consult our planning permission guide for Ireland or check with your local authority.
Some timber structures may qualify as temporary structures with different planning considerations, which could simplify the approval process.
Foundation and base preparation
A proper foundation is crucial for the longevity of your timber garage. Options include:
A concrete slab provides the most common and durable option, creating a solid, level surface for your garage. Concrete piers or strip foundations offer a less expensive alternative while still providing good support. For smaller structures, a compacted gravel base with timber frame may be sufficient.
Key considerations include ensuring the base extends at least 150mm beyond the garage dimensions on all sides, incorporating proper drainage to prevent water pooling, and using a damp-proof membrane to protect the timber from ground moisture.
DIY installation vs professional assembly
When your timber garage kit arrives, you have two options for assembly:
DIY installation typically requires 2-4 people depending on size and calls for basic carpentry skills and tools. While it can save €1,000-€3,000 in labour costs, you’ll need to set aside 2-5 days for completion depending on the structure’s size and complexity.
Professional installation ensures proper assembly and reduces the risk of errors. Installers have specialised tools and experience, typically completing the job in 1-2 days. This option includes warranty on workmanship and allows you to avoid physical labour and time commitment.

Factors to consider when choosing between DIY and professional installation include your experience level, available time, physical capability, and budget constraints.
Delivery and lead times
When planning your timber garage project, factor in these delivery considerations:
Most standard garage kits are available with fast delivery options, though typical lead times range from 2-8 weeks depending on customisation requirements and current demand.
Delivery requirements include adequate access for large vehicles and space to unload materials. For detailed information about delivery schedules and requirements, consult our delivery information page.
Insulation options and finishing touches
To make your timber garage more comfortable and usable year-round, consider these insulation and finishing options:
Floor insulation is essential for preventing cold and dampness from rising through the base. Wall insulation can be added between or against timber walls to improve thermal efficiency. Roof insulation is crucial for temperature regulation throughout the seasons.
For heating, options include electric radiators or panel heaters, portable gas heaters for occasional use, and infrared heating panels for energy efficiency.
Interior finishes might include timber preservatives and treatments to protect against moisture, interior wall cladding or lining for a finished appearance, and proper ventilation systems to prevent condensation.
For comprehensive guidance, our guide on how to insulate a garden shed provides techniques that apply equally well to timber garages.
Customisation options
Personalising your timber garage or carport is easy with various customisation options:
Additional windows improve natural light, making the space more pleasant for workshop activities. Partitioned interior spaces create separate storage or workshop areas to maximise functionality. Extended roof overhangs provide extra protection from Irish weather.
Custom door configurations, including side entrance doors and various vehicle access options, can be tailored to your specific needs. Exterior finishes such as paint or stain in various colours allow you to match your home’s aesthetic. Additional security features like reinforced doors or window shutters provide peace of mind.
