We deliver quality construction

After three years working from a spare bedroom, our Compact garden room from Modular House has completely transformed how I work — proper insulation, steel frame durability, and a genuine office feel that the whole family now uses daily. From quote to installation it was straightforward, professional, and delivered on time with no planning permission needed. Six months in and I'd do it again without hesitation.

As a piano teacher working from home with a growing family, Modular House gave me a dedicated, beautifully finished studio in just 6 weeks, no planning permission needed. The soundproofing, insulation, and heat pump keep it comfortable and quiet year-round, and my students and their parents love how professional it feels. It gave us our family home back. Worth every penny.

After years of putting off extending, Modular House made it straightforward — the steel-frame build was remarkably fast, the fully itemised quote meant no surprises, and the finish is lovely. Our 25sqm rear extension completely changed how we use our home; instead of moving, we got the open-plan space we always wanted. Would absolutely recommend to anyone thinking about extending but dreading the process.

AoifeSantry, Dublin 9

Being a site manager, I know quality when I see it. The galvanised steel frame, continuous PIR insulation, and solid fabrication are the real deal, not a garden shed with fancy cladding. I've been training four or five times a week in my Compact since February, and between the heat pump warming it in minutes, it's already paying for itself. At €29,500, it's saved me gym fees, petrol, and an hour a day commuting. And my partner's delighted the Livingroom is finally free of weights.

    Why choose Steel Frame over timber or block?

    Steel is faster, stronger, and more precise. It builds roughly 30% faster than traditional methods, will never rot, warp, or twist, and offers superior thermal values, keeping your space warm and energy bills low.

    Do I need planning permission?

    Most of our projects are "Exempted Developments" and do not require planning permission. This typically applies to Garden Rooms under 25m² and single-story rear extensions under 40m², provided the roof height does not exceed 2.5m. We will confirm your specific compliance during our initial site survey.

  • 03

    Is my build guaranteed?

    Yes. We provide a comprehensive 25-year structural warranty on our steel frames. Because steel is inorganic and durable, you can be confident your investment is protected against the elements for decades.
