DomiDo is an AI-assisted modular outdoor construction platform developed by Avvyland Limited (United Kingdom). People describe what they want to build outdoors — a planter, a garden bench, a heat-pump cover, a privacy screen — or upload a 3D model of it, and the platform converts that idea into a physical kit of universal interlocking blocks plus the fasteners and instructions to assemble it at home. The company sells universal blocks and fasteners only; every construction shown on the platform is a user-generated design, and the platform's role in those constructions is enablement rather than authorship. This page is the orientation document for anyone new to the project: it covers the problem DomiDo addresses today, the solution the platform provides, the four pillars of its competitive position, the product family it sits inside, and what customers actually buy. The image below shows the universal block library that every kit is composed from.
Building a custom outdoor structure is harder than it should be. Anyone wanting something specific for their garden, terrace, balcony, or driveway has to choose among three unattractive options. Hiring a contractor delivers good quality and total customisation but at a cost far outside what most homeowners are willing to pay for a single bespoke object. Buying a generic prefabricated product keeps costs manageable but the catalogue is shallow and the dimensions never quite fit the actual space, so customers compromise on size, shape, or style. Doing it themselves can be inexpensive but the required skills — carpentry, masonry, structural awareness — are specialist, failure rates are high, and safety concerns are real. A fourth path — digital-to-physical — could combine the customisation of contracting, the affordability of prefab, and the agency of doing it oneself, but no consumer platform currently bridges that gap. AI image and 3D-model generation has advanced rapidly, yet translating a 3D shape into a buildable, durable, outdoor-rated construction kit requires a stack of capabilities (computational geometry, materials science, manufacturing logistics, assembly sequencing) that no consumer product currently offers. DomiDo's reason to exist is to provide exactly that fourth path.
DomiDo lets people start from an idea, a sketch, a photograph, or a 3D model, and arrive at a physical kit at their door. The kit is composed of universal interlocking blocks plus the fasteners that hold them together, produced once at industrial scale and recomposed for every design. Customers enter the platform through one of two doors. In Upload mode, a user with their own 3D model — exported from Blender, SketchUp, Fusion 360, or any other tool that produces a standard 3D format — uploads the model and the platform analyses it, repairs any defects, voxelises it onto the block grid, optimises the block layout, validates structural integrity, and produces a bill of materials with assembly instructions. In AI mode, a user without a 3D model describes the object in plain language ("a raised garden bed, L-shaped, two metres by one and a half, knee height"), optionally attaching a reference photograph, and the AI generates a 3D model in steps the user can review and refine before it feeds into the same pipeline as Upload mode. Upload is the lower-cost path aimed at users who already have a digital model; AI is the higher-cost path aimed at users who can describe what they want but cannot model it.
Both doors converge on the same engine: a proprietary processing pipeline (internally known as dd-mesher) that takes any 3D shape and produces everything needed for physical construction. The engine repairs the input mesh, converts the smooth shape into a grid of interlocking blocks, optimises the layout to minimise block count while maintaining structural integrity, assigns fasteners, validates the design against a catalogue of structural and assembly rules, and emits a step-by-step assembly sequence together with a complete bill of materials. The output is deterministic: the same input always produces the same kit. Every kit is then assembled from the same library of universal blocks plus a small set of finish parts. The connection mechanism is patent-pending and uses a self-complementary tetrahedral relief, so any block can connect to any other block in any orientation with no male-or-female distinction and no fixed top or bottom — a single set of moulds serves an unlimited catalogue of designs. The blocks are designed for outdoor service: weather-resistant, ultraviolet-stable, and rated for a long continuous service life across a wide temperature range. Materials selection is preliminary; the leading candidate is an industrially-mouldable polymer with documented outdoor durability, with other resins remaining open candidates that do not change geometry.
A third-party logistics partner picks each kit at the warehouse from the universal block inventory, packs it into one or two boxes depending on size, and ships it via a tracked carrier. Inside the box the customer finds numbered blocks grouped by build step, a fastener pack, a finish kit where the design specifies one, and a quick-start card with a QR code that opens the build companion — the in-app assistant that walks the customer through assembly block by block.
The combination of four capabilities is what makes the position defensible: no current competitor offers all four in one product. The first pillar is AI-assisted design from text, image, or 3D model input, which lowers the threshold from "you need to model what you want" to "you need to describe what you want". The second pillar is the proprietary 3D-to-block conversion with a patent-pending interlocking system, which turns any 3D shape into a buildable kit deterministically. The third pillar is functional outdoor-scale structures rather than toys or display pieces — actual outdoor garden, terrace, and utility objects. The fourth pillar is the designer marketplace, a community-driven gallery where any user can publish, monetise, and protect their own designs; it comes online after the initial product launch and provides the long-run network effect that strengthens the platform over time.
DomiDo sits inside a wider product family operated by Avvyland Limited. Alongside DomiDo (physical block construction) lives Avvyland, a separate interactive 3D environment for visualising and sharing creations. The two products share a brand and ownership but each has its own surface, its own documentation, and its own audience. The relationship is bidirectional and optional: an object designed in DomiDo can be displayed in Avvyland for promotional or social purposes, and an object built in Avvyland can serve as a prototype for physical manufacturing through DomiDo. Neither product requires the other.
The product a customer pays for is the physical kit: a set of universal blocks chosen to compose the design they ordered, plus the fasteners that join them, plus a build licence for that specific design (the right to assemble it for personal use), plus access to the digital build companion that guides assembly. A designer publishing on the marketplace may optionally enable design uniqueness protection, a feature that prevents very similar designs from being published on the platform within a defined distance and time window. The customer does not receive a downloadable 3D source file. Designs stay on the platform; what travels home is the physical realisation.
The platform reaches its final form in four phases. Phase A is the public interest beta: customers browse the gallery, save designs, and register non-binding interest in a kit, with no manufacturing and no money movement. Phase A.5 opens once a design accumulates enough interest: the platform issues pre-order invites, the customer's card is verified through a Stripe SetupIntent but not charged, and the order sits in a "cleared to build" queue. Phase B begins once a manufacturing batch is queued: the card is charged through a Stripe PaymentIntent, the kit ships, and customers assemble at home with the build companion. Phase C opens the full designer marketplace, with designers publishing their own kits, setting royalty rates, and earning from each pre-order, and with uniqueness protection via embedding-based similarity coming online here.
