What's the difference between the three sets?

The Planning / Study Set is what Town & Country planning needs to approve the house: floor plans, elevations, sections and a site plan. Construction Drawings Only is the builder's set — foundation plan, construction sections and details, electrical, MEP and a material list — for a design that is already approved. The Full Construction Set is both, so you can submit, price and build from one purchase.

Do I need the stamp add-on?

If you are submitting for a permit in Barbados, yes — the submission has to carry a registered architect's stamp for your specific property. If you are still studying options, budgeting, or building somewhere the stamp is not required, you can buy the drawings now and add the stamp later.

What does the license actually allow me to do?

The Single-Build License lets you construct the design once, on one property, and share the set with your contractor, engineer and the permit authority. The Multi-Build / Developer License lets you construct it the number of times stated on your order — for a housing scheme or repeat units. In both cases the drawings stay our copyright and cannot be resold or redistributed as plans.

Multi-build / developer licensing adds 50% to whichever set you choose. Stamping is never bundled — it is added below.

Add Professional Stamp & Local Permit Review

Our registered architect reviews the set against your specific lot and current Barbados requirements, then stamps it for submission.

Review of the set against your lot, setbacks and orientation
Mark-ups where the standard design needs adjusting for your property
Architect's stamp and signature for Town & Country submission
One round of permit-review correspondence

Why it is a separate line item: This is a separate line item because stamping is a personal licensing act: the architect is signing off on your particular property and build, not on the plan file itself. It cannot be bundled into an off-the-shelf drawing package.
