Residential design: starting from use

Design a home starting from how you actually live

House, duplex or condo: before anything is drawn, the way a place is lived in has to be clear — rooms, circulation, daylight, storage and needs that will change. The mandate starts with a clear brief, then with options tied to the building and its context.

Turn a daily need into a design decision

Educational example: a household needs another bedroom while retaining the living area and limiting unnecessary circulation. Before fixing a construction area, compare room relationships: what should be close, what needs privacy and which access routes must remain. The table is a preparation worksheet, not a plan or an Archidep completed project.

Use the same comparison criteria for each option. Gaining a room is not necessarily an improvement if another becomes hard to access. Identify assumptions too: a wall thought to be movable or a proposed opening is not an established technical possibility. Plan the necessary checks before developing the option.

The situations that start a drawing project

A home whose rooms no longer match daily routines, a parent or housemate moving in, a wish to catch more daylight or gain storage, preparation for a project that will have to go through the municipality: starting points that do not call for the same work.

The first conversation establishes which of these starting points actually describes your project, and whether the answer belongs with design, an addition, a renovation or another process.

  • Which rooms are missing and which are poorly used?
  • What uses will the house still have to support in a few years?
  • Which elements absolutely must be kept?
  • Will the project need a permit or another process?

From the brief to design options

The brief gathers the needs: rooms, circulation, daylight, storage and how occupants will change. It acts as a filter to compare options before a solution is drawn, instead of the other way around.

Depending on the mandate, the work may stop at an initial study, continue to full drawings or include preparation of documents for the municipality. These are separate scopes that the quote must name.

The building may also raise questions belonging to other professionals: structure, electrical, mechanical. Those contributions are coordinated, but their drawings and their responsibility stay separate from architectural design.

What the mandate delivers, what stays separate

The quote describes the documents handed over during the mandate: the brief, the design drawings and the documents needed for decisions; if the municipal submission is part of the scope, the items of that file.

Generally separate: construction work, engineering drawings, municipal fees and, unless the mandate provides for them, submission follow-up or site supervision. The quote must state these limits before work begins.

  • Delivered: brief, design drawings, permit documents if the mandate includes them
  • Coordinated: required professionals and exchanges useful to the file
  • Separate: construction, engineering, municipal fees, site supervision

Who produces what around the project

The owner brings the desired way of living, the decisions and the information about the building. Archidep structures the brief, produces the design and coordinates exchanges. The municipality reads the zoning and, depending on the project, processes the permit application.

Other professionals join in depending on the building and the scope. The quote should identify who produces which document, so that no responsibility is left unanswered.

Preparing the first conversation

Missing records do not prevent a start: say what exists and what is missing. A missing drawing is not a blocker; it is part of the information to establish from the outset.

  • Building address and municipality or borough
  • Photos or descriptions of the rooms involved
  • Drawings, certificate of location or older documents, if available
  • Household priorities and uses to preserve
  • Indicative budget and target schedule

Studio schedule and municipal schedule

The design schedule depends on available records, decisions to make and the scope agreed in the quote. It is defined with the mandate, not before it is accepted.

The municipality sets its own requirements, meetings and review timelines. A prepared file does not mean an authorization is granted, and no design schedule replaces a municipal decision.

Questions and answers

Must I choose a layout before the first conversation?

You may bring ideas, but describe the problems and priorities first. An online plan can illustrate an atmosphere or room relationship; it does not establish suitability for your building, site or applicable rules. State whether you need an options study or development of a selected option.

Are permit drawings sufficient for construction?

The purpose and detail level of documents must be defined. A municipal application does not automatically include every construction detail, product selection, other discipline’s drawing or construction-phase service. Identify what will be delivered and what must be completed before requesting prices or starting work.

Before commissioning work

Three points to clarify in your quote

When comparing proposals, ask for written answers to these questions. Project-specific terms are those set out in the accepted proposal.

What if the city refuses after I have paid for the services?

Archidep reviews feasibility and applicable requirements early to identify constraints before preparing the application. If the City later requests corrections or issues an unfavourable decision, first connect the reason to the submitted design: a missing record, design change and special approval need different responses. Included revisions and correspondence are defined in the contract; additional work is scoped separately. Payment covers agreed professional services and does not guarantee the municipal decision.

How long will the project take?

The schedule is established after reviewing the request: a targeted check, commercial premises application and major transformation require different production. It accounts for records to obtain, checks, drawing preparation and your approvals. Share deadlines at the first conversation. Urgent processing may be considered subject to availability, with an additional fee disclosed before commitment. Office production remains separate from City review and other contributors’ timing.

Are revisions included?

The service proposal includes provision for revisions. The contract specifies their number, scope and applicable stage. Distinguish an adjustment to the selected design, municipal comments and a new request changing the brief. Changes beyond the agreed scope should be defined before additional production. Retain approved decisions and drawing versions so each change can be identified.
