Bringing clarity to residential building

Homeowners deserve to know exactly what they're paying for. Yet most residential projects in the UK go out to tender on drawings alone, leaving each builder to interpret the scope differently.

Builder Standard Limited built OneSpec to fix that: a single, descriptive Schedule of Works that every builder prices against. It combines experience from the construction industry with careful use of AI, always separating what's confirmed from what's assumed, and never filling gaps with guesswork.

The result is quotes you can compare, fewer surprises on site, and better relationships between homeowners and the builders they hire.
