Follow this practical walkthrough to assemble the eitech House with BBQ. Get the steps, checkpoints, and common mistakes to avoid for a solid build.
Quick answer
To build the eitech House with BBQ, sort all parts first, then follow the manual in order: base, walls, roof, and finally the BBQ detail. Tighten screws only after the frame is square, and check that every hole aligns before adding the next panel. Expect about one to two hours for a careful build.

Building the eitech House with BBQ is a satisfying project that rewards patience and a tidy workspace. The kit includes metal strips, plates, screws, and nuts, plus the parts for a small barbecue setup. Because the model is assembled with real fasteners, the order you tighten things matters as much as the parts you choose.
This walkthrough gives you a clear sequence, checkpoints to catch problems early, and honest notes on where beginners usually slip. Keep the manual nearby, but use these steps to understand why each stage matters. By the end, you will have a stable house model and a better feel for how eitech parts work together.
Before you start: sort parts and set up your space
Empty the box onto a tray or shallow bowl so small screws and nuts cannot roll away. Group parts by type: flat bars, angled pieces, plates, screws, and nuts. The eitech House with BBQ uses standard M4 hardware, so keeping lengths separate saves time later. A magnetic parts tray or a muffin tin works well for this.
Read through the manual once before touching a screwdriver. You do not need to memorize it, but you should know where the BBQ attaches and how the roof comes together. Clear a flat, well-lit surface at least the size of a placemat. Good lighting matters more than a fancy tool set.
- Common mistake: starting to screw parts together before sorting. You will spend more time hunting for a nut than building.
- Checkpoint: every part type is in its own pile and the manual is open to the first step.
Step 1: Build the base frame
Start with the base rectangle. Connect the long flat bars to the shorter end pieces using screws and nuts, but leave them slightly loose. The base sets the footprint for everything else, so it needs to be flat and square. If you tighten fully now, later panels may not line up.
Once the rectangle is formed, place it on your flat surface and press down gently on all four corners. If it rocks, one joint is twisted. Loosen the screws at the high corner, realign, and tighten just enough to hold. A square base makes the walls much easier to attach.
- Common mistake: overtightening the first joints. Leave them snug, not locked, until the walls are on.
- Checkpoint: the base sits flat with no rocking and the corners form right angles.
Step 2: Attach the side walls
With the base square, add the vertical corner posts and then the side panels. Work on one wall at a time. Attach the bottom edge first, then the top edge, then the vertical connections. This order lets you nudge the panel into alignment without fighting the whole frame.
If a hole does not line up, do not force the screw. Check that you are using the correct length and that the panel is not flipped. The eitech system relies on overlapping holes, so a small shift at one corner can throw off the next panel. Fix alignment now rather than later.
- Common mistake: mixing up screw lengths. Using a long screw where a short one belongs can block a nut or dent a panel.
- Checkpoint: each wall is attached at all four corners and the frame still sits flat.
Step 3: Install the roof and gable
The roof usually comes as two angled sections that meet at a ridge. Attach the gable ends first, then the roof panels. This sequence gives you a stable triangle to rest the roof on. If your kit uses curved flat bars for the roof edge, they go on after the main panels are secure.
Do not tighten the ridge connection until both roof halves are in place. A slight looseness lets you center the ridge line. Once centered, tighten the ridge and then the lower roof edges. Press gently on the roof to confirm it does not shift.
- Common mistake: tightening the ridge before both roof panels are attached. This pulls the roof out of alignment.
- Checkpoint: the ridge is centered and the roof feels solid when you press down lightly.
Step 4: Assemble and attach the BBQ
The BBQ is a small sub-assembly, so build it separately on your tray. It typically includes a base, a grill surface, and a frame. Follow the manual for the exact layout. Keep the screws loose until all BBQ parts are connected, then tighten them evenly.
Attach the finished BBQ to the house at the point shown in the manual. This is often a side wall or a small platform. Support the BBQ with one hand while you start the first screw. Once one screw is in, the rest are easier. Do not overtighten, as the BBQ parts are small.
- Common mistake: attaching the BBQ before it is fully assembled. Build it flat first, then mount it.
- Checkpoint: the BBQ sits level and does not wobble when you touch it.
Step 5: Final tightening and stability check
Go around the entire model and tighten every screw a little at a time, working in a circle. This distributes tension evenly and prevents the frame from twisting. Do not crush the metal; snug is enough. If a screw spins freely, the nut may be cross-threaded. Back it out and restart.
Set the house on a flat surface and press gently on the roof and walls. It should feel rigid. If it flexes, find the loose joint and tighten it. A stable model is easier to handle and looks better on display. Make any final adjustments to the BBQ position now.
- Common mistake: skipping the final tightening pass. Loose screws work their way out over time.
- Checkpoint: the model does not wobble, and all screws are snug without stripped threads.
Build sequence at a glance
- Sort and set up: Empty the box, group parts by type, and read the manual once before starting. A tidy tray prevents lost screws and speeds up every later step.
- Build the base frame: Connect the base rectangle and leave the screws slightly loose until the walls are on. Check that the base sits flat and square before moving on.
- Attach the walls: Add corner posts and side panels one wall at a time, bottom edge first. If a hole does not line up, stop and check for a flipped panel or wrong screw length.
- Install the roof: Attach gable ends, then roof panels, and center the ridge before tightening. The roof should feel solid when you press gently on it.
- Assemble and mount the BBQ: Build the BBQ flat on your tray, then attach it to the house with one screw first. A level BBQ looks better and is less likely to loosen.
- Final tighten and check: Tighten all screws in a circle, a little at a time, and test for wobble. A rigid model is the sign of a job done well.
Parts that help with this build
- School building kit 1: Ideally suited as teaching material for craft lessons in primary school. Suitable for group work, up to a maximum of 3 students per box. Up to 3 models can be built at the same time. If you are building the House with BBQ as a group project, this kit gives you extra parts and a structure that supports multiple builders.
- Axle profile 4x150 mm galvanized: The eitech Axle Profile 4x150 mm galvanized is a component from the eitech range, offered under SKU 01358P. It is listed with the Manufaktur tag. A spare axle profile is useful if your model includes moving parts or if you want to reinforce a joint that sees repeated handling.
- Lock washer Ø 10 mm x 1 mm, blue: The eitech Lock Washer Ø 10 mm x 1 mm in blue is a small fastening component intended for use with compatible threaded connections. Adding a lock washer under a nut can help keep screws from loosening on parts that get touched often, like the BBQ or roof.
Building the eitech House with BBQ is a straightforward project when you work in order and keep your screws snug rather than tight. Sort your parts, build the base square, and save the BBQ for last. If you take your time, you will end up with a model that feels solid and looks sharp on the shelf.
