Modular extensions, also known as prefabricated or off-site constructed extensions, represent the fastest growing segment of domestic residential improvement in Ireland.
Unlike traditional masonry builds that subject your home and family to months of wet trades, dust, scaffolding, and unpredictable weather delays, modular room pods are engineered in temperature-controlled factory facilities. While groundworks and micro-pile foundations are prepared in your garden, the structural envelope is assembled concurrently.
The completed modular pod is delivered by flatbed transporter and craned directly into position. Weather-tight enclosure is typically achieved within forty-eight hours.
Precision cut Structural Insulated Panels (SIPs) or light gauge steel frames eliminate thermal bridging, achieving U-values as low as 0.12 W/m²K and exceptional airtightness.
Because building takes place in a factory environment, supply chain material costs and labor hours are strictly controlled, eliminating weather related budget overruns.
Modular extensions are governed by identical planning legislation as masonry extensions. Ground-floor extensions up to 40 square metres to the rear of your house remain planning exempt, provided you preserve at least 25 square metres of private open garden space and stay below statutory roof height thresholds.
Modular extension costs in Ireland typically range from €1,950 to €2,750 per square metre. Total turnkey budgets for a 30 to 40 square metre prefabricated room pod range from €60,000 to €95,000 depending on ground screw foundations and internal glazing specifications.
Like traditional masonry builds, single-storey rear modular extensions up to 40 square metres are generally planning exempt, provided you leave at least 25 square metres of private open garden space and comply with height restrictions.
While factory fabrication takes four to eight weeks, on-site installation and crane positioning are usually completed in just one to three days, reducing domestic disruption by over seventy percent compared to traditional blockwork.
Yes, factory precision manufacturing ensures airtight construction and structural insulated panels (SIPs) that easily achieve A-rated Building Energy Ratings (BER), compliant with Irish Part L building regulations.
