The Handover Day Protocol: What We Inspect Before Handing Over the Keys

The final day of a RoomRise build is not simply a matter of packing up tools and handing over keys. It is the culmination of a rigorous, documented process — a day dedicated to verification, testing, and walkthrough. We call it the handover protocol. Before you take possession of your garden room, we subject every element to a multi-point quality control check. Nothing is left to assumption. Every door latch is tested, every window seal is inspected, every electrical socket is load-checked. This is the standard we hold ourselves to, and the standard you deserve.

This guide explains exactly what happens on handover day, what we inspect, and why this final stage matters so much.

Why a Documented Handover Matters

The handover is your assurance that the building performs exactly as specified. A garden room is a complex assembly of structural, thermal, electrical, and mechanical systems. Each of these systems must function individually and integrate seamlessly with the others. A door that sticks slightly, a socket that is loose, or a seal that is imperfect may seem minor on day one — but over years of daily use, these small defects become major frustrations.

A documented handover eliminates these issues before they become your problem. By following a standardised, multi-point check sheet on every project, we ensure that nothing is overlooked and that every element of the building meets our specification before we hand over the keys.

The Multi-Point Quality Control Check

Our handover protocol follows a comprehensive check sheet that covers every aspect of the building. The inspection is conducted by your project manager in your presence, so you can see exactly what is being tested and ask questions as we go.

The check sheet is divided into four categories: structural alignment, glazing and doors, electrical and heating, and finishes. Each item is inspected, tested, and signed off.

Structural Alignment and Shell Integrity

The first category verifies that the building is structurally sound and dimensionally accurate.

Laser Level Frame Alignment

We begin with laser level verification of the wall frames and floor. The timber frame must be perfectly plumb, level, and square. A frame that is even a few millimetres out of alignment will cause problems with door operation, cladding fit, and long-term stability. Using a precision laser level, we check:

Wall plumb: Every wall is checked vertically at multiple points to ensure absolute upright alignment.
Floor level: The floor cassette is checked across its entire area to confirm a flat, level surface with no high or low spots.
Corner squareness: Each corner is checked for precise 90-degree alignment, ensuring that doors, windows, and cladding fit correctly.
Ceiling level: The ceiling is verified as level and at the correct height, with no sagging or deflection.

If any measurement falls outside our tolerance — which is exceptionally tight — the frame is adjusted before handover. This is the foundation of long-term performance.

Shell Weathertightness

We inspect every external junction for weathertightness. The EPDM rubber roof is examined for seamless bonding, with particular attention paid to edges, corners, and any penetrations such as flues or vents. Wall cladding is checked for secure fixing and correct gap formation, ensuring the ventilated cavity behind remains functional. The breathable membrane is verified as fully intact beneath the cladding.

Glazing and Door Operation

The second category focuses on the glazing and doors — the moving parts that receive the most daily wear.

Window Seals and Operation

Every window is opened, closed, locked, and checked. We inspect:

Seal compression: The weather seals around each window must compress evenly when closed, ensuring no draughts or water ingress.
Smooth operation: Hinges and friction stays must operate smoothly without binding or resistance.
Lock engagement: Multi-point locks must engage fully and securely at every locking point.
Glazing integrity: The double-glazed units are inspected for scratches, cracks, or seal failures.
Trickle vents: Ventilator trickle vents are tested for correct operation.

Door Latch and Lock Testing

The bi-fold or sliding doors are the most complex mechanical elements of the building. We test them rigorously:

Smooth tracking: Doors must slide or fold effortlessly along their tracks, with no catching or resistance.
Latch operation: Every latch and lock must engage cleanly and release smoothly.
Multi-point lock alignment: The multi-point locking system must engage at every point along the door height, providing security and weathertightness.
Threshold seal: The threshold at the base of the doors must form a continuous seal when closed, preventing water ingress during heavy rain.
Draught proofing: All draught seals are inspected for correct compression and continuity.

Doors that do not operate perfectly are adjusted on the spot. A garden room door should open with one finger — that is the standard.

Electrical, Heating, and Data Verification

The third category verifies that all building services function safely and correctly.

Electrical Load Testing

Every electrical circuit is tested under load. This is not a visual inspection — it is a functional test. We verify:

Socket functionality: Every double socket is tested to confirm it delivers correct voltage and that the wiring is properly polarised.
Switch operation: Every light switch is tested for correct function.
Circuit protection: The consumer unit is checked to confirm that all circuits are correctly protected by residual current devices (RCDs) and miniature circuit breakers (MCBs).
Certification: All electrical work is certified and signed off by a qualified electrician. You receive the electrical installation certificate at handover.

Heating Response

If your garden room includes electric heating, we test the system to confirm correct operation. The heater is switched on, and we verify that it reaches the set temperature and that the thermostat functions correctly. The thermal performance of the room — achieved through 100mm or more of PIR insulation and a wall U-value of around 0.18 W/m²K — means the space should reach a comfortable temperature quickly and retain it efficiently.

Internet and Data Runs

For garden offices, reliable internet is essential. We test all data points to confirm they are correctly terminated and connected. A wired data connection provides faster, more stable internet than Wi-Fi, which is why we recommend installing data points in any room intended for work or entertainment.

Interior Finishes and Fixtures

The fourth category covers the interior finishes — the elements you will see and touch every day.

Plaster finish: The skimmed plasterboard walls are inspected for smoothness, with no trowel marks, ridges, or hollows.
Paint finish: The painted surfaces are checked for even coverage, with no drips, runs, or missed patches.
Flooring: The flooring is inspected for secure fitting, correct expansion gaps, and no lifting or creaking.
Skirting and architraves: All trim is checked for secure fixing, tight joints, and clean finish.
Lighting: All light fittings are checked for secure mounting and correct function.
Socket and switch plates: All faceplates are checked for secure fitting and correct alignment.

Any imperfection is corrected before handover. The interior should feel finished, polished, and ready to use.

The Maintenance Walkthrough

Once the inspection is complete, we walk you through the long-term care of your garden room. This is a practical, jargon-free conversation covering:

Cladding maintenance: How and when to re-treat timber cladding to preserve its appearance and durability. Siberian larch and thermally modified timber require minimal maintenance, but occasional cleaning and oiling will keep them looking beautiful for decades.
EPDM roof care: The rubber roof is virtually maintenance-free, but we explain how to keep it clear of debris and what to inspect annually.
Glazing care: How to clean and maintain the aluminium frames and double-glazed units to preserve their appearance and performance.
Ventilation: How to use trickle vents and heating to manage condensation and maintain good air quality.
Warranty procedure: What to do if you discover a defect, how to contact us, and what is covered under the 10-year structural warranty.

You receive a printed maintenance guide, the electrical certificate, the warranty documentation, and a full set of keys.

Why We Insist on This Protocol

Some builders view handover as a formality — a quick walk-round, a handshake, and a departure. We view it differently. The handover is the moment when our work becomes your space. It is the final opportunity to verify that every promise made during the design and quotation stages has been fulfilled.

By insisting on a documented, multi-point protocol, we protect both you and ourselves. You receive a building that has been rigorously tested and verified. We receive the assurance that our work meets the standard we promise. And if any issue arises in the future, we have a documented baseline against which to assess it.

Ready for Your Keys

A garden room is a significant investment, and the handover is your guarantee that it has been delivered to the highest standard. Our multi-point quality control check ensures that every element — from the structural frame to the final coat of paint — meets our exacting specification. When we hand you the keys, you can step into your new space with complete confidence.
