Who We Are

An architecture and construction practice built on drawing, engineering, and follow-through.

Archistructure Investment Group was founded in 2018 by architects Harun Rashid Turay and Musa Saidu Mansaray, graduates of Limkokwing University of Creative Technology. What began as a two-person drawing practice has grown into a full studio covering architecture, structural engineering and project management — carrying every commission from first sketch to handover.

We work across residential, commercial, cultural and institutional projects, holding the same standard of rigor whether the brief is a family home or a 150,000 sqft campus.

What We Do

Three disciplines, one continuous process

From the first concept sketch to the final walkthrough, our teams stay attached to the project — nothing gets handed off blind.

DWG 01

Architectural Services

2D and 3D architectural drawing, aesthetic and interior/exterior design, and landscaping — shaped around how the space will actually be used.

DWG 02

Engineering Services

Civil 2D plans, structural analysis and detailing, land survey and bill of quantities — the calculations behind every drawing.

DWG 03

Project Management

Supervision, construction management, quality control and resource coordination, keeping timelines honest from groundbreaking to handover.

How We Work

Our Process

Four stages, repeated on every commission — from a first meeting to a finished building.

01

Consultation

We meet to understand your vision, requirements and project scope in detail.

02

Concept Design

Initial designs and concepts are developed directly from that brief.

03

Development

Detailed design development, technical drawings and documentation follow.

04

Implementation

We supervise execution and construction through to handover.

“Archistructure carried our home from a rough sketch to a finished house without losing a single detail along the way.”
Client, Residential Home Design — Freetown
“Their engineering team caught structural issues our first contractor missed entirely. That alone paid for the consultation.”
Client, Eco Residences
“What stood out was follow-through — the same team that drew the plans was still on site the week we opened.”
