About XCornerstone
Rwanda's Premier Architecture Marketplace, connecting homeowners, developers, and businesses with professional architecture plans.
Our Story
Built for Rwanda, by Rwandans
XCornerstone was founded by Rugwiza Dieudonne, director of XCorners Contractor, from a simple but powerful observation: buying a professional architecture plan in Rwanda was unnecessarily difficult. Clients had to know the right architect, negotiate informally, and wait weeks for designs, often with no quality guarantee.
We set out to change that. Based in Kigali, our marketplace brings together Rwanda's best architects and thousands of ready-to-use plans, residential, commercial, hotels, and beyond, all in one place, available for instant download.
Today, XCornerstone is trusted by homebuilders, real-estate developers, and contractors across Rwanda. Every plan meets local building codes and is delivered instantly after a secure mobile money payment.
