Interior design spec sheet template

A specification sheet records what an item is meant to be. It should let someone distinguish the proposed product, finish, size, and revision without inferring those details from an image.

How to use this template

Use the sheet for product-level information. Keep the FF&E schedule as the room-by-room quantity register and the finish schedule as the surface register. Terminology varies between practices; agree the role of each document with the people using it. Before issuing a revision, trace the item through its plan, schedule, budget, and decision record; preserve the prior issue.

  1. Assign a reference before adding the item to a drawing.
  2. Record sourced information separately from assumptions.
  3. Review the specification alongside its room schedule and drawings before any purchasing decision.

Follow one reference across a revision

The specification owns product identity and sourced attributes. The FF&E schedule owns where an item belongs and its quantity; the finish schedule owns surface assignments. A drawing locates or describes the item. Keep these roles explicit so copying information does not create several competing sources.

Suppose a different sofa is proposed for F-01. Preserve the old issue, record the candidate as a proposed revision, and identify each affected record. A stable F-01 reference means the design slot remains traceable; it does not mean the replacement is automatically suitable or approved.

Review before use

  • An image is not proof of model, dimensions, or finish.
  • Do not overwrite a revision without recording the change.
  • Do not label an item approved because it appears in a concept board.

Units, source information, and US use

The worked example keeps its original nominal metric dimensions. For a US project, choose and label a primary imperial or metric convention, distinguish item counts from areas, and document any display conversion and rounding. Never relabel metric values as imperial or treat conversion as site verification.
