Concrete Base & Foundations
Properly designed and poured concrete slab or pad foundations — not timber decking on blocks. The base is the foundation of everything above it.
A properly built garden room — insulated, wired and finished. Your home office, gym or retreat in the garden.
A garden room is one of the most versatile additions to a Cork home. Whether you need a dedicated home office away from the house, a gym, a games room, a studio, or simply a quiet retreat at the end of the garden — a properly built garden room delivers year-round usable space without the disruption of extending the main house.
Timothy Bowen Building & Maintenance builds garden rooms that are genuinely insulated, properly wired, and finished to the same standard as the house. We do not install flat-pack kit rooms. We build from the ground up — concrete base, insulated frame, proper cladding, electrics, and internal finishes that will last decades.

From concrete base to finished interior — here's everything we build into a Timothy Bowen garden room.
Properly designed and poured concrete slab or pad foundations — not timber decking on blocks. The base is the foundation of everything above it.
Timber stud frame with full insulation to current standards — walls, floor and roof. Your garden room will be warm in winter and cool in summer.
Timber cladding, fibre cement, or composite cladding options. Flat roof with single-ply membrane or pitched roof with slates — properly waterproofed and detailed.
High-performance double-glazed windows and external door, fitted correctly. Bi-fold or sliding door options available for maximum light and garden connection.
Full electrical first and second fix — consumer unit, sockets, lighting, data points and USB charging. Armoured cable run from the house, certified on completion.
Plasterboarding, skim plastering, skirting, internal doors and painting. We hand over a finished room, not a boarded shell.

There's a significant difference between a flat-pack garden room and one that's properly built. We build properly — the same standards as any building project we take on.
The electrical installation is certified by a registered electrician and handed over with the appropriate REC certification. Your insurance requires this.
We don't hand over a bare shell. Your garden room is plastered, painted, skirted, and ready to furnish. One contractor, one payment, one finished room.
We flag any planning issues before you commit. If your intended garden room needs permission, we'll tell you — and advise on the most straightforward route.

"Timothy built us a 20m² garden room for use as a home office and it's exceptional. Properly insulated, warm in winter, quiet, and finished to the same standard as the house inside. Best investment we've made in the property."
"We had a garden room built as a gym and games room. Timothy advised us on the best position in the garden for light, built it to a high spec, and the electrical installation was comprehensive. Absolutely delighted with it."
"Compared three quotes for our garden room and Timothy's was the most comprehensive. He was the only one who mentioned the planning exemption limits and built within them. The finish is outstanding and it adds real value to the house."
