Bespoke Garden Rooms

At Mulholland Carpentry & Joinery Ltd, we specialise in building luxury garden rooms. Whether you need a home office, bedroom, gym, playroom, or even a self-contained annex, we provide expert craftsmanship and tailored solutions to maximise your space.

Our garden room conversion process ensures that your new space is warm, energy-efficient, stylish, and fully compliant with UK building regulations.

Our Step-by-Step Garden Room Process

1. Initial Consultation & Planning

Every project begins with a detailed consultation where we discuss your vision, assess the garden space, and provide expert advice on the best design solutions.

✅ Understanding Your Needs – Home office, gym, studio, guest room, or relaxing retreat—we tailor the design to your lifestyle.
✅ Site Assessment – Access, ground levels, drainage, orientation/sun path, trees/roots, and proximity to boundaries.
✅ Regulatory Compliance – We confirm the route under UK planning (e.g., permitted development) and ensure all required approvals and building regulations are met.

2. Groundworks & Foundations

With the design finalised, we prepare a solid, long-lasting base for your new garden room.

🔹 Foundation System – Options include reinforced concrete slab, ground screws with steel frame, or concrete pads—selected to suit soil conditions and tree constraints.
🔹 Services Provision – Trenching for power/data (and water/waste if needed), with safe routes and correct depths.
🔹 Damp Protection – High-quality damp-proof membranes and detailing to prevent moisture ingress.

3. Structure & Weatherproof Shell

We construct a robust, insulated shell designed for year-round use.

🔹 Engineered Timber Frame – Treated structural studs and sheathing for strength and durability.
🔹 Roof & Cladding – EPDM single-piece membrane or equivalent premium roofing, breathable membranes, and your choice of exterior cladding (cedar, thermowood, composite, or render).
🔹 Openings – High-performance doors and windows installed with precision, including seals, trims, and rainwater goods.

4. Insulation & Energy Efficiency

Comfort is non-negotiable. We maximise energy performance so the room is warm in winter and cool in summer—this is a key part of what sets us apart.

✅ Floor, Wall & Roof Insulation – Generous insulation depths with a continuous vapour control layer and airtightness detailing.
✅ Windows & Doors – Double or triple glazing for thermal efficiency and security.
✅ Ventilation – Designed airflow (trickle vents, extracts, or MVHR options) to control condensation and maintain excellent air quality.

5. Electrical, Heating/Cooling & Plumbing

We integrate modern services so your garden room is truly plug-and-play.

🔹 Electrical – Consumer unit, dedicated circuits, LED lighting, sockets, exterior lighting, and optional smart controls.
🔹 Heating/Cooling – Options include electric radiators, underfloor heating, or a highly efficient split AC heat pump.
🔹 Plumbing (Optional) – For WCs or kitchenettes, we install discreet water and waste solutions with correct falls or macerators where appropriate.
🔹 Connectivity – Hard-wired data (Cat6) or mesh Wi-Fi solutions for reliable internet.

6. Interior Finishing, External Details & Handover

We deliver a polished, ready-to-use space—inside and out.

✔ Interior Finishes – Plasterboarding and skim, premium paints, and your choice of flooring (LVT, engineered wood, tiles, or carpet).
✔ Bespoke Joinery – Built-in desks, shelving, storage, or feature walls to suit how you’ll use the space.
✔ External Touches – Steps, decking, paths, and landscaping tie the building seamlessly into your garden.
✔ Quality Check & Certification – Thorough snagging, compliance documentation, and a full handover so you can move in immediately.
