What to Expect from Construction Studies in 2025
With the 2025 Leaving Cert Construction Studies paper fast approaching, we’ve analysed trends from 2020–2024, including deferred papers, to give you the most accurate predictions possible. Here’s everything you should focus on.
📏 Section A – Drawing & Graphical Questions (Answer 3 of 5)
Expect one sketching question—often from walls, stairs, or windows.
📌 Key areas likely for 2025:
-
Building Services – Typical detail of plumbing, electrical layout, hot/cold water, or renewable energy.
-
Structural Details – Timber frame wall, concrete foundations, insulation.
-
Stairs – Elevation or sectional sketch of a timber staircase.
-
Scale Drawing – Elevation/floor plan in correct proportions.
-
Window Detail – Sash or casement – focus on insulation and air tightness.
✅ Pro Tip: Practice your neat freehand sketching and remember labels matter!.
🧠 Section B – Construction Theory (Answer 4 of 6)
📌 Question 1 – U-Value & Insulation
-
Heat loss, thermal conductivity, and modern methods to reduce U-value.
-
Possibly linked to NZEB (Nearly Zero Energy Building) standards.
🛠️ Question 2 – Foundation & Substructure
-
Strip foundations, radon barrier, site preparation.
-
May ask for labelled sectional drawing.
🚪 Question 3 – Doors & Windows
-
Airtightness, triple-glazing, low-E coatings.
-
Hinge types or locking mechanisms.
🌬️ Q4–Q6 – Services, Regulations & Sustainability
-
Plumbing or Heating – Underfloor heating, solar panels, heat pumps.
-
Building Regulations – Fire safety, Part B/C.
-
Ventilation – Passive stack or mechanical systems.
-
Sustainability – Low carbon materials, rainwater harvesting.
✨ Question 6 – Modern Construction / Site Management
-
NZEB compliance, waste management, health & safety on site.

📊 What Came Up in 2020–2024?
Here’s a snapshot of what’s been tested most often:
-
2024: Stairs, U-Values, Timber Frame Walls, Rainwater Harvesting
-
2023: Windows, Passive Design, Site Safety, Heat Recovery Ventilation
-
2022: Stairs, Solar Panels, Insulation, Foundations
-
2021: Doors, Airtightness, Ground Floor Detail, Wind Turbines
-
2020: Plumbing Layout, Concrete Floors, Waste Water Systems
✅ Pro Tip: Know the glassware, setup diagrams, safety precautions, and typical sources of error.
🧠 Frequently Asked Questions
What topics are most likely for Construction Studies in 2025?
Focus on sustainability, insulation, modern energy systems, and ventilation. Timber stairs, window detailing, and foundations are strong drawing candidates.
📄 Deferred Papers – Do They Matter?
Yes. Overlap is common. If the 2024 deferred paper is available before your exam, study it. Several topics from 2022 and 2023 deferred papers reappeared on main papers the following year.
👀 Watch this space: Repeating patterns matter—sketches and theory often rotate predictably
