Quick answer
Choose Silver for design and approval drawings, Gold when you also need electrical drawings, plumbing drawings and a bank BOQ, or Platinum for the broader documented set including opening schedules, tile layouts, bathroom details and setting out. Confirm structural engineering and consultancy scope separately in your written proposal.
Silver: resolve the design and approval set
The current advertised Silver package starts at LKR 150,000. Its listed deliverables are a site visit, house layout, exterior 3D view and approval drawings. It suits a homeowner who wants those stages resolved and will arrange the remaining engineering and construction information separately. An approval drawing is not a substitute for every construction detail. Before appointing a builder, identify the extra drawings your building actually requires.
Gold: add the core services and bank BOQ
Gold starts at LKR 200,000 and includes the Silver deliverables plus electrical drawings, plumbing drawings and a bank BOQ. It is useful when a homeowner needs coordinated service positions or documents for a lender. Discuss the bank’s required format early. A bank BOQ supports lending assessment; confirm whether a more detailed tender BOQ is needed for contractor comparison. The package title alone should never be treated as confirmation of structural calculations or site supervision.
Platinum: document more decisions before building
Platinum starts at LKR 400,000. The website lists the Gold deliverables together with a door and window schedule, tile layout, bathroom details, unlimited revisions and a setting-out plan. These documents help clarify opening sizes, finishes and dimensional coordination. Agree how revisions are managed once drawings are approved or construction begins, because late design changes can still affect contractor time and cost.
How floor area affects the fee
The current package page states that the packages apply up to 2,000 square feet and that additional area above this attracts LKR 75 per square foot. For an illustrative 2,400-square-foot house, 400 extra square feet multiplied by LKR 75 gives LKR 30,000 above the relevant starting package price. This illustration is not a project quotation: obtain a written fee covering your site, complexity, taxes where applicable and requested services. These are design fees, not house construction budgets.
Choose by missing information, not the cheapest label
List what your contractor, lender and approving authority need. Then check which documents you already have and whether they remain suitable. A homeowner managing construction remotely may value more documented decisions; a small renovation may require a tailored appointment rather than a standard new-house package. For an apartment, retaining wall or complex foundation, request a project-specific proposal. Do not assume the residential package automatically covers specialist approval or engineering work.
Questions to settle before appointment
Ask for the drawing issue schedule, revision procedure, deliverable formats and the person coordinating architecture, structure and MEP. Confirm whether authority charges, surveys, testing, specialist consultants, tender administration and site inspections are included or separately charged.

Frequently asked questions
Does a Structa design package include construction?
No. The advertised packages cover design and documentation; construction is contracted separately.
Does Gold automatically include structural engineering?
The public Gold deliverables list electrical drawings, plumbing drawings and a bank BOQ in addition to Silver. Confirm structural engineering explicitly in your written scope.
