About Jmax Builders
A working builder you can also buy a plan from.
We started Jmax Builders Ltd because too many projects in Kenya were started with drawings nobody could build from, and BOQs nobody could trust. We're a small, focused team that designs, prices, and constructs — and sells the same builder-grade documents we use on site.

What we believe
Four principles, every project.
Builder-first
Every drawing and BOQ we publish is something our own crews would build from. No theoretical templates.
Measured & honest
Clear inclusions, clear exclusions, indicative rates. We'd rather under-promise than surprise you mid-project.
Buildable details
Standard block sizes, conventional spans, sensible finishes — designs optimised for Kenyan supply chains.
Accountable
Insured operations, weekly progress reporting, defects period on every build.
The team
Small, accountable, on the tools.
