Our Build Process

We’ve completed garden house projects throughout Cork including Ballincollig, Douglas, and Carrigaline. Each build follows a structured process from site assessment through final handover, with transparent pricing and regular progress updates.

Initial Assessment

Our team visits your Cork property to assess available space, ground conditions, and utility access. We measure dimensions, evaluate soil stability, and identify any drainage requirements. During the visit, we discuss your intended use – whether it’s a home office, guest house, or rental unit – and explain Cork County Council planning requirements.

You’ll receive a detailed quote including material specifications, construction timeline (typically 6-10 weeks), and total cost. We provide transparent pricing with no hidden fees, and all work is backed by our 20-year warranty.

Professional Service

Our construction team handles foundation work, framing, roofing, electrical installation, and final finishing. We use insulated wall panels rated for Irish weather conditions and install double-glazed windows for energy efficiency. Each build includes waterproof membranes, proper ventilation, and full electrical certification.

We’re fully insured and registered for construction work throughout Cork. Projects include regular site inspections, and we coordinate with utility providers for electrical connections. Most builds complete within 6-10 weeks from groundwork start to final inspection.

Quality Assurance

Every garden house undergoes structural inspections during foundation, framing, and roofing stages. We test electrical systems before final certification and verify insulation standards match building regulations. Final walkthrough includes checking window seals, door operation, and weatherproofing before handover.

All work meets Cork County Council requirements and includes documentation for planning compliance. Our 20-year structural warranty covers materials and workmanship, with 10-year protection against weather-related issues.

When You Need a Garden House

Cork homeowners build garden houses for four main reasons: creating rental income (Airbnb or long-term tenants), accommodating elderly parents while maintaining privacy, establishing dedicated home offices away from household distractions, or housing teenage children who need independence. Garden houses avoid extension costs while adding property value.

Custom Designs – Tailored solutions to fit your garden space and needs.
High-Quality Materials – Durable, weather-resistant, and eco-friendly options.
Affordable & Cost-Effective – Competitive pricing with no hidden costs.
Quick Turnaround – Fast and efficient construction timelines.
Compliant with Building Regulations – Fully licensed and insured professionals.

What to Expect During Construction

Construction follows a clear sequence from groundwork through final inspection. Timelines depend on size – a 4m x 3m office typically takes 6-8 weeks, while larger two-bedroom units require 8-12 weeks. We schedule work to minimize garden disruption and coordinate material deliveries with your availability.
