What’s Included
What’s Included in Your Granny Flat
Everything you need is included — from design and groundworks to the final finishes. We manage the entire process, delivering a fully finished, ready-to-live-in home with no hidden extras or loose ends.
Design & Consultation
We begin by understanding your vision, your site, and your budget. Working closely with you, we design custom granny flats and garden apartments that maximise space, comfort, and long-term value while complementing your existing property.
Groundworks & Foundations
Built on solid, fully compliant foundations to the same standard as a traditional house or extension — not a temporary or lightweight solution. All groundworks, insulation, structural elements, and service connections are carefully completed for strength, durability, and long-term performance.
ICF Construction
We build using premium ICF (Insulated Concrete Formwork) construction, a modern method known for superior insulation and structural strength — resulting in homes that are warm, quiet, and cost-effective to run all year round.
Roofing
A range of roofing options, with our most popular being a contemporary flat roof finished with high-performance Lava 20 — excellent weather protection, longevity, and a sleek, low-maintenance finish.
Fully Fitted Kitchen
A high-quality, fully fitted kitchen designed around your space and style. Choose from a range of finishes and colours, with everything supplied and installed — from cabinetry to worktops.
Bathroom
A fully fitted, modern bathroom finished to a high standard, including tiling, sanitaryware, and a clean, comfortable layout designed for everyday use.
Windows & External Doors
High-quality, made-to-measure PVC windows and external doors, providing excellent insulation, security, and durability for a bright, energy-efficient living space.
Flooring & Decoration
Finished with durable laminate flooring throughout, with a wide selection of colours available. Walls are professionally painted white, creating a bright, modern interior ready for personal touches.
Plumbing & Electrical
Fully installed plumbing for kitchen, bathroom and utility needs. Complete electrical fit-out with sockets and lighting in every room, three kitchen downlights, two external lights and electric oil-filled radiators.
Internal Finish & Carpentry
All internal doors, skirting, and carpentry fully fitted and professionally finished. The result is a high-end, move-in-ready home built to the standard of a traditional house.
Built For How You Live
Comfortable Spaces for the People Who Matter Most
Whether it’s for family, independence, or income, we make building your granny flat simple and stress-free from start to finish.
Senior Living
Designed for comfort, accessibility, and ease of living. Warm, efficient, and tailored to individual needs — a safe, cosy space that supports independence while staying close to family.
Supported Living
A safe, comfortable space where young adults with additional needs can enjoy independence while staying close to family support — balancing care, privacy, and everyday confidence.
Generational Living
Makes it easy for families to live together while still enjoying their own space — privacy and comfort, while keeping everyone connected for day-to-day support.
Rental Income
A granny flat can generate up to €14,000 per year tax-free under the Rent-a-Room scheme — a smart way to earn extra income from your available space.
