Before releasing bespoke work for production
A material approval is one part of the decision. What drawings, samples and installation details need to establish before a maker begins.

A beautiful stone surface may be approved while the supports beneath it are still unresolved. A cabinet can have an agreed finish while the maker is waiting for the lighting details. Before bespoke work goes into production, those different decisions need to be understood together.
Bespoke pieces can give a room a proportion, function or material character that a collection piece cannot offer. The final result depends on how clearly the design reaches the workshop. Once material is cut or a component manufactured, an overlooked detail may require alteration, additional cost or a compromise in the room.
Know what is ready to be made
A production release authorises a defined piece or part of the work to proceed. It should identify the current drawings and specification, the approvals already received and any information still outstanding.
The client’s approval of appearance has its own purpose. It may establish colour, texture or an overall composition. The maker also needs dimensions, construction information and the relationship to neighbouring work. A client should be able to approve the intended result without being asked to resolve specialist details outside that decision.
If only part of a package can proceed, state exactly which part. A general “approved” message can leave the maker uncertain about whether an unresolved component is included.
Shop drawings: the piece and its setting
A fitted cabinet meets walls, floors and ceilings. A stone basin meets taps, drainage and surrounding finishes. Those connections influence the object’s proportions and the way it can be installed and maintained.
Read the design drawings, specification and supplier shop drawings together. The design drawings set out the intended piece and its setting; the supplier’s shop drawings show the fabrication and assembly proposed for that piece. Confirm that dimensions and finishes agree across the drawings and match the approved sample references. Record who prepares, reviews and approves each package. Where the piece depends on existing or adjoining work, establish who verifies the relevant site measurements before production release.
Consider delivery in the same review. A piece drawn as a single object may need to enter through a stair or lift before reaching its room. The maker and installation team need an agreed route and, where applicable, an assembly sequence before those constraints become a problem on arrival.
Ask samples a specific question

A finish sample can help establish colour and texture. An assembly mock-up can show a junction, an edge or a lighting effect. Decide what needs to be seen and at what scale, then record the reference approved by the client and design team.
A small stone sample cannot describe the full movement of a slab. A loose piece of fabric cannot demonstrate an upholstered corner. Where that feature matters to the design, the sample needs to answer the relevant question.
At Sikder Haus, the bespoke Portoro basin was designed and commissioned for handwashing in the dining area. Its workshop and installed views connect the carved stone object to its finished setting. The material, shape and fittings can be read together across those stages.
Make a technical comment easy to act on
Take an illustrative cabinet with integrated lighting: the drawing shows a closed back but no route to replace the LED driver. The question affects both maintenance and the finished appearance of the cabinet.
A useful comment would read: “Show the access panel and confirm how the LED driver can be replaced after installation. Coordinate the panel with the rear finish and adjacent shelving before releasing this detail for manufacture.” Add the drawing number, revision, responsible party and required response date.
This is an example of a review question, not a reported defect on an AD’ project. Its value lies in asking for a definite response that can be checked before the affected work proceeds. The appointed specialists remain responsible for developing and verifying their respective details.
Give the workshop a clear instruction

Before release, the agreed information should identify the piece to be made, its current specification, the approvals it relies on and any limitations. The maker needs to know which drawings and samples govern the work and who confirms a proposed change.
If a junction or component remains unresolved, keep that status visible and decide whether other work can proceed independently. Once the answer is received, check the revised information against the original question. A comment marked closed is useful only when the affected detail has actually been addressed.
When an independent review helps
A focused review can be useful when manufacture is approaching and the owner or project team needs a second examination of a defined package. The scope should state what information will be checked, what deliverables will be provided and how comments return to the appointed designers and suppliers.
AD’s Technical & Project Review can examine agreed drawings, details and specialist connections before tender or production. If a piece is approaching manufacture, discuss it with the studio. Describe the decision ahead and its timing; any current drawings can help establish what the review should cover.
