Marimar

What Marimar does

Marimar bv is a privately-held Belgian construction firm headquartered at Landbeek 40, 1730 Asse, in the Flemish-Brabant province, specializing in total renovation and eco-building services for residential homeowners. The company delivers an integrated service portfolio covering rough construction (masonry, structural works, facade renovation and insulation, flat roofs), interior finishing (drywall, flooring, painting), electrical installation and ventilation, heating systems (heat pumps, condensing boilers, underfloor heating), carpentry (windows, doors, stairs), and bespoke custom work (kitchens, bathrooms, wardrobes, furniture). Its eco-building line uses natural, damp-open materials — including kalkhennep (lime-hemp) insulation, lime plaster, lime chape, wood fiber, cellulose, and sheep wool — and installs the patented BossCover Circular EPDM roof system (Certefix), a fully demountable, adhesive-free flat-roof solution.

The company operates on a project-based professional-services revenue model, generating one-time contract revenue from custom renovation and eco-building projects, supplemented by discrete Eco Building Consultancy and Interior Design Advice services. Pricing is quote-based and not publicly disclosed; sales run direct-to-consumer through the firm website, two GSM phone lines, and email, with on-site measurement and consultation as the standard conversion path. There are no intermediaries, resellers, or marketplace channels, and the firm operates exclusively within Flemish-Brabant.

Marimar is owned and operated by co-founders Mattias Vanderstraeten (eco-building consultancy, on-site measurement) and Maja Simac (interior design, 3D visualization), who together bring 17 years of combined experience in eco-building and custom interiors. The firm is a Quick-Step Master Installer, a co-operative member of Woonder (natural materials supply and knowledge network), a participant in the CTC Smart sustainable construction commission, and is featured as a 'Doener' on the Vlaanderen Circulair platform. No external investment, parent company, or subsidiary relationships are indicated in the available data.

Scale indicators1 record

Expansion highlights4 records

Broad incumbents

• Wienerberger Belgium: Leading brick and building-envelope solutions provider in Belgium. Comparable through overlap on facade renovation and sustainable masonry — a category Marimar also covers under its Gevel and Ruwbouw services.
• Daikin Belgium: Global HVAC and heat-pump manufacturer with a Belgian subsidiary. Marimar installs Daikin-equivalent heat pumps as part of its Wooncomfort offering; comparable through overlap on energy-efficient heating retrofits in Flemish homes.
• Velux Belgium: Danish roof-window manufacturer with Belgian operations. Marimar installs Velux dakramen within its Schrijnwerk carpentry line, making Velux a comparable adjacency through shared attic-renovation and daylighting solutions.
• Unilin (Quick-Step): Belgian flooring and panels group behind Quick-Step. Marimar is a listed Quick-Step Master Installer for laminate flooring, so the two companies are explicitly partnered; comparable through shared end-customers and overlapping flooring-installation activity.
• Vandenbussche: Mid-sized Belgian general construction and renovation contractor with multi-region coverage. Comparable as a Flemish general contractor competing for renovation contracts, though with much broader geographic and segment reach than Marimar.
• Renson: Belgian leader in ventilation, sun protection, and outdoor living. Overlaps with Marimar on home-comfort and ventilation installations but operates at significantly larger scale with a broad product portfolio rather than bespoke eco-renovation.

Regional players

• Ecobouwers: Dutch platform/network of ecological builders and renovators. Comparable as a fellow eco-construction community operating in the neighbouring Dutch market, sharing the natural-materials and circular-building orientation that defines Marimar.

Emerging players

• Steico: European manufacturer of natural wood-fibre insulation and structural building products. Comparable through shared emphasis on ecological, vapour-open insulation materials used in Flemish eco-renovation projects.

Others

• Buildwise: Belgian construction innovation and research centre (formerly BBRI). Comparable as an ecosystem participant whose technical guidance and standards shape eco-construction practice that Marimar applies on Flemish renovation sites.
• Woonder: Belgian co-operative focused on natural building materials and knowledge-sharing in eco-construction. Marimar is a co-operative member and uses Woonder-sourced kalkhennep and lime products; comparable as a fellow practitioner in the Flemish natural-building ecosystem rather than a direct competitor.
