What ECON3 does

ECON3 bv is a private Belgian ecological construction company headquartered in Wijgmaal (Leuven region), founded in 2010 and co-led by Jorre Van Damme (finance and administration) and Jan Van Droogenbroeck (operations), supported by a small team of craftsmen totaling 1–10 employees. The firm specializes in timber frame construction (houtskeletbouw) as its core offering, alongside roofing, facade work, extensions, complete renovations, foundation work, and zinc installations, serving residential property owners primarily in the Flanders region. Pricing is custom per project based on scope, materials, and complexity, with no published rate cards or turnkey packages; the firm delivers wind-tight shells and refers clients to trusted specialist contractors for HVAC, electrical, and plumbing work outside its scope.

The technical differentiator is its ecological construction methodology: damp-open building envelopes using natural materials such as cellulose insulation from recycled paper, wood fiber boards, and lime-based plasters, paired with Firestone EPDM single-piece roofing membranes and Trespa or Eternit Natura/Equitone facade panels. Underlying technology is construction know-how and curated material systems rather than software, automation, or proprietary IP. The go-to-market relies on direct client relationships, referrals from architects, a company website, and a Facebook page — no third-party distribution, marketplace listing, or institutional channel partnerships are disclosed.

ECON3 is a project-based, direct-to-client construction services provider with no recurring revenue contracts, no SaaS or platform revenue, and no disclosed enterprise customers. No funding rounds, institutional investors, acquisitions, or M&A activity are present in the data, and the vacancies page explicitly states the team is complete, signaling a steady-state operating posture rather than an expansion-phase build-out.

Core offering

ECON3 is an ecological construction company that builds and renovates residential properties primarily using timber frame construction (houtskeletbouw). It delivers wind-tight new builds, extensions, optopping (floor additions), complete renovations, roofing, facade work, foundations, drainage, masonry, insulation, and zinc work for individual homeowners, working directly with clients and architects while subcontracting specialized technical aspects.

Product overview

ECON3 is an ecological construction company offering timber frame construction as its core business, complemented by a comprehensive suite of building services including roofing, facade work, extensions, complete renovations, and floor additions. The company distinguishes itself by not offering turnkey solutions but instead provides wind-tight new builds and renovations while recommending trusted contractors for specialized work outside their scope. Their service portfolio includes foundation work, drainage, rough construction and masonry, various facade types (wood, stone, panel materials, plaster, slate), zinc work, and insulation using primarily cellulose from recycled paper.

Functional benefit

Products and services

• Houtskeletbouw (Timber Frame Construction) ECON3's core construction service specializing in timber frame construction for new builds, extensions, and floor additions on existing buildings. The lightweight structure requires minimal foundation work and enables construction on top of existing volumes, with sustainably sourced materials and preference for indigenous wood over tropical hardwoods.
• Dakwerken (Roofing) Complete roofing services for residential properties including saddle roofs (zadeldak), flat roofs with Firestone EPDM rubber membrane installed in a single piece, sarking roofs with external insulation, and green roof options, using materials such as clay tiles, slate, and zinc.
• Gevelwerken (Facade Work) Facade installation services including wooden facades (horizontal, vertical, and open-joint systems in various profiles), stone facades, panel materials (Trespa, Eternit Natura), natural lime-mineral plaster systems (hydrocon), and slate cladding.
• Aanbouw (Extensions) Service adding new living space to existing homes, typically via a foundation slab and support columns or walls for large window sections, with extensions often connecting to existing structures through large openings and possible at multiple levels.
• Totaalrenovatie (Complete Renovation) Full renovation services ensuring complete exterior envelope insulation from sill to ridge, with various options for structure, extensions, repurposing, and window installations to achieve economically and ecologically optimized concepts.
• Optopping (Floor Addition) Conversion of existing roof space into a fully habitable floor using timber frame construction without requiring modifications to existing foundations, due to the lightweight materials and structure of the timber frame.
• Nieuwbouw (New Construction) Complete new residential construction services from excavation and drainage through concrete slabs, timber frame, roofing, and facade cladding, including foundation preparation with insulating glass granulate base.
• Funderingswerken (Foundation Work) Excavation work for projects of all sizes, including basements, foundations, concrete slabs, and underground insulation as needed.
• Riolering (Sewerage/Drainage) Installation of all drainage pipes around the house and under concrete slabs for kitchen, bathroom, toilet, and rainwater discharge, including rainwater tanks, infiltration pits, and septic tanks.
• Ruwbouw en Metselwerken (Rough Construction and Masonry) Renovation masonry, interior modifications, new openings, steel beam and load-bearing wall installation, and facade bricklaying, including in combination with timber frame construction.
• Isolatie (Insulation) Insulation services with primary preference for cellulose insulation made from recycled paper treated for pest and fire resistance, suitable for roofs and timber frame construction, with alternative materials including mineral wool, flax, hemp, and cotton-wool for inaccessible areas.
• Zink (Zinc Work) Zinc installation for facades (available in Nature, Quartz, and Anthra colors in standard or custom widths) and roofs (from slightly sloped to curved structures), also used for gutters, downspouts, roof edges, wall caps, and facade gutters.

Direct peers

• Wyckaert Groep: Belgian construction group active in residential and utility building, with operations across Belgium. Comparable as a Belgian residential/commercial builder; competes for similar renovation and new-build projects but at a significantly larger scale and broader service portfolio than ECON3.
• Bostoen: Large Belgian residential construction company building single-family homes and apartments across Flanders and Wallonia. Directly comparable as a Belgian homebuilder serving residential clients, though Bostoen operates at much greater scale and with broader mainstream offerings rather than ECON3's ecological specialism.
• Compagnie de Construction (CdC): Belgian general construction and renovation firm with a multi-trade service portfolio covering residential and commercial work. Comparable to ECON3 in offering renovation, extensions, and roofing, though CdC operates at a larger scale and is not specialized in ecological timber-frame construction.

Broad incumbents

• Saint-Gobain: French-headquartered global building materials and construction solutions group with extensive Belgian presence (insulation, plasterboard, facades). Comparable as a broad incumbent whose insulation and wall systems are widely used in Belgian construction; competes indirectly with ECON3's cellulose/lime-based systems through conventional mainstream solutions.
• Wienerberger: Austrian-headquartered European leader in building materials (bricks, clay blocks, roofing, facade systems) and provider of wall and roof solutions including energy-efficient systems. Relevant as a broad incumbent shaping the Belgian construction materials and wall-system market that ECON3 sources from and competes against via its timber-frame alternative.
• Xella: European manufacturer of building materials including autoclaved aerated concrete (Ytong) and calcium-silicate units used in residential wall systems across Belgium. Relevant as a broad incumbent offering mainstream wall-system alternatives that compete with ECON3's timber-frame approach in the Belgian residential market.

Others

• Etex: Belgian-headquartered global building materials group (promat, equitone, eterboard panels, fiber cement siding) that supplies facade panels — including Eternit Natura/Equitone, which ECON3 specifies as a core facade material. Comparable as an ecosystem supplier whose products ECON3 integrates into its facade offerings.
