Builders Across South Africa
Expert builders of Nutec houses, log houses and alternative building solutions. Full turnkey construction from assisting with plans and approvals to handover, no subcontracting the parts that matter.
Looking For A Builder?
Looking for a Nutec house builder in South Africa? Cornerstone Construction Solutions builds Nutec homes and log homes across all 9 provinces, from Gauteng to the Western Cape to KwaZulu-Natal.
Nutec houses are built from fibre cement panels: lightweight, durable, and faster to construct than brick. They resist moisture, fire, and pests. They insulate well, which keeps energy costs down. And they cost roughly 20–30% less than a traditional brick build.
Log houses are a different option, best suited for lodges, farms, and residential properties where a natural timber look is the goal. We select and cut each log to fit precisely, so the structure is tight, weather-resistant, and built to last. Both methods are NHBRC compliant. We handle everything from foundation to final finish and we can assist with plans and municipal approvals.
We quote honestly, communicate clearly and show up on schedule.

FAQs
Nutec & Log Houses FAQs
Everything you need to know before you build.
Nutec houses are constructed using fibre cement panels made from cement, cellulose fibres and sand. These lightweight panels are highly durable, weather resistant, and provide excellent insulation properties. The panels are moisture resistant and do not rot, warp or attract insects.
The cost varies based on size, design, location and finishes. Generally, Nutec homes are 20–30% more cost-effective than traditional brick construction. WhatsApp us at +27 76 850 4940 for a free, personalised quote tailored to your requirements and budget.
