Flat-Pack vs Assembled Dollhouses: Freight, Assembly and Returns

What the two formats actually mean

Flat-pack means panels, fittings and hardware shipped unassembled in one carton with an instruction sheet. On a dollhouse the panel count follows the structure rather than the size: a tabletop cottage might use 12-20 panels, a two-storey house 25-40, and a 133 cm three-storey villa with a lift and a garage 50-80 including the working parts. Most models join with cam locks, dowels and screws, with metal or nylon hinges on the doors, and the small parts travel in a fittings bag taped inside the carton.

Assembled means the house leaves the workshop built, travels in a larger carton with corner protection and internal bracing, and arrives ready to place. Everything commercial follows from that one difference: how much air you ship, who does the joinery, and who owns the problem when a door rubs or a chair is missing from the bag.

Most of this catalogue ships flat-pack. A minority of models can be quoted assembled, and the format is confirmed per model rather than assumed from the size band.

The carton cube is the whole argument

The ranges below are measured across the 130-model catalogue published in November 2026. A 40HQ has about 68 m3 of usable volume on paper and roughly 60 m3 as a working number once pallets, wheel arches and door clearance are allowed for. Volume, not weight, is what fills a container of dollhouses.

Format	Carton cube	Gross weight	Indicative units per 40HQ	Typical damage pattern	Who assembles
Flat-pack, tabletop under 40 cm	0.01-0.05 m3	0.5-9 kg	about 2,300	carton corners, fittings bag loss	retailer or customer, 20-30 min
Flat-pack, standard 40-80 cm	0.03-0.12 m3	5-15 kg	about 790	long-panel edges, hardware bag loss	retailer or customer, 40-60 min
Flat-pack, large 80 cm and above	0.10-0.25 m3	10-25 kg	240-400	long-panel bowing, corner damage	retailer or customer, 60-90 min
Assembled, standard	0.15-0.30 m3	8-18 kg	200-400	joints loosening, door and corner damage	nobody
Assembled, large	0.30-0.60 m3	12-28 kg	100-200	joints loosening, handling weight	nobody

An assembled house takes roughly two and a half to three times the cube of the same model flat-packed, and on the large band it can be more. Palletising narrows the gap slightly but loses 10-15 per cent of container volume to pallet footprints and stacking gaps, so a mixed load has to be planned carton by carton rather than by average.

The figures are indicative and confirmed per model on quotation, because a different carton grade, an extra inner tray or a custom finish moves the cube. For the full method, see the packing and container loading page.

Assembly is a customer-service step, not a factory step

Flat-pack moves assembly to whoever receives the goods. For an importer supplying independent retailers, that is usually the retailer's customer, which makes the instruction sheet part of the product rather than a document in the box.

The parts of a well-made flat-pack dollhouse are worth asking for by name:

Numbered panels. A panel with a code and a matching position on the drawing saves more time than a clearer photograph.
A fittings bag divided by step. Screws, dowels, cam locks, knobs and stickers in one bag is where assembly stalls.
Pre-fitted hinge plates. Drilling and mounting hinge plates is the slowest step on a house with doors, and pre-fitted plates remove it.
A screw gauge on the panel. The wrong screw length in a 12 mm panel is the most common assembly failure a retailer sees.
A note on door adjustment. A door that rubs after assembly is a support call, and two lines on the sheet prevent most of them.

Three assembly mistakes come up repeatedly in buyer feedback: cam locks fitted the wrong way round, hinges mounted before the door is aligned, and the wrong screw length. All three are design and documentation problems before they are customer problems, and all three are cheap to fix at the specification stage.

Assembled houses remove the burden but add handling weight. A 25 kg carton that has to be carried upstairs is a delivery problem, and an assembled house is dragged rather than lifted. If the channel is home delivery, flat-pack usually wins on handling as well as cube.

Returns and after-sales

The failure modes differ, so the returns pattern differs too. The table below is the pattern to plan for rather than a claim about any one model.

Failure	More common in	Why it happens	What to plan
Missing or damaged fittings	flat-pack	small bags split or are left out at packing	a spares bag per 10-20 cartons, part codes on the sheet
Door rubs or will not close	both	panel tolerance, hinge adjustment	adjustable hinges, an assembly note
Corner crushed, panel chipped	both	stacking, hub handling, single-wall cartons	corner protection, double-wall carton, drop check
Joint loosened after sea freight	assembled	container heat and vibration, timber movement	moisture specification agreed per batch, glue plus mechanical fixing
Wrong assembly	flat-pack	ambiguous instructions	photo steps, numbered panels, a support line

For flat-pack, the cheapest fix is a spares allowance agreed before production: a spare fittings bag per 10-20 cartons and a small parts kit held at the importer, plus 1-2 per cent of hinges and figures. For assembled, the equivalent is carton engineering and a pre-shipment drop check on the packed unit. Neither is expensive at the planning stage and both are awkward to add after the container has sailed.

Which format suits which buyer

Importers and distributors usually choose flat-pack: warehouse cost is per cubic metre, and the same container carries two to three times as many units.
Retailers with physical shops often want a small number of assembled display houses and flat-pack stock behind them. A display unit can travel in the same container if the loading plan leaves room for it.
Marketplace and e-commerce sellers usually choose flat-pack, but should ask for the carton drop performance, a fittings kit and a manual in the market language before committing to a listing.
Nurseries and daycares often prefer assembled so that nobody has to check a joint a child may have built, and they buy in small quantities.
Gift and seasonal channels generally choose flat-pack, because the cube cost matters more than the assembly time and the carton travels to a retail shelf rather than to a playroom.

The hybrid that works for many buyers is to sample assembled and ship flat-pack. The sample proves the joinery, the finish and the door alignment; the order travels in the smaller carton. We confirm per model whether the same house can be supplied in both formats.

What to do next

Send the format you are considering, the destination market and the annual volume, and we will confirm carton cube, gross weight and container fill for the specific models. If you are undecided, ask for one sample of each format: the assembly hour and the carton size are easier to judge in the hand than on a spreadsheet. Start with the packing and container loading page for the container arithmetic, check assembly and spare parts for the fittings and parts route, or send the model list through the quotation form.
