What SESE does

SESE, Lda. is an Angolan private limited company (founded 2004) that operates as an integrated construction and engineering firm headquartered in Miramar, Luanda, with a construction yard and in-house testing center (Centro de Teste) in Kilamba. The company employs approximately 11 people and serves residential, commercial, industrial, and institutional clients across Angola, including the Government of Angola and NAIL Airport. Its service portfolio spans the full building lifecycle — architectural design (using BIM), interior design, urban planning and topography (using drone, GNSS, and total station surveying), landscaping, civil construction, renovations and maintenance, electrical/hydraulic/HVAC installations, and project management — with a sanitation and cleaning sub-brand (RS22 Service) launched in 2025 and an e-commerce furniture storefront (Loja) under development.

The company makes money primarily through one-time project contracts and professional services engagements, priced on a quote basis (pricing is not publicly disclosed). Customer acquisition is sales-led: inquiries flow through the corporate website (sese.ao), dedicated email channels ([email protected], [email protected]), and phone lines (+244 937 076 113, +244 955 124 045). Distribution is single-country/domestic (Angola), with named clients spanning hospitality (Turimar Business Hotel), healthcare (Clínica Diamond, Rinawell), food & beverage (Artfood), aviation (NAIL Airport), and oil & gas (Kwame Oil and Gas). The firm emphasizes a multidisciplinary team with 20+ years of individual accumulated experience, sustainability focus, and post-project support as differentiators. There is no evidence of external funding, public listing, or international operations.
