Moving a staircase changes the route through a house twice: where you leave one floor and where you arrive on the other. A position that looks efficient downstairs may use valuable space upstairs or create a landing that interrupts bedroom access. The best comparison therefore begins with both floor plans and a section through the building.
A related guide to consider while planning this work is Staircase Replacement: Repair, Rebuild or Relocate?.
At this stage, the question is not which balustrade looks best. It is which location gives the household a useful connection between levels while accommodating the stair, its opening, landings, headroom, supporting construction and surrounding circulation. Once that arrangement is credible, the detailed stair design can develop around it.
Set a specific reason for relocating the stair
Describe what the existing position prevents you from doing. Perhaps the stair divides the only living room, blocks a practical kitchen layout or sends traffic through a private area. A clear reason helps you judge whether each alternative creates enough improvement to justify the work.
Identify what must be preserved. You may need to retain a particular bedroom, keep a direct route from the entrance or maintain access to a bathroom during a staged renovation. Those constraints should appear on the designer’s brief before options are drawn.
Then ask whether the problem concerns the entire stair or only its approach. An altered doorway or room arrangement might improve circulation without moving the stair. If relocation remains the preferred direction, that comparison helps establish the benefit you are buying.
Agree on the household priorities
Rank the outcomes that matter most: usable living space, bedroom privacy, shorter daily routes, future adaptability, daylight or easier furniture movement. An option may perform well on some and poorly on others. Ranking them prevents the most visually striking drawing from dominating the discussion.
Keep essential access separate from optional space
Do not count a landing or required approach area as spare room space simply because it is empty on the plan. People need somewhere to arrive, turn and continue. The design professional should establish the necessary clearances and assess the applicable requirements.
Start with measured information on both levels
Obtain reliable dimensions for the existing floors, walls, openings and levels. Marketing plans can suggest possibilities but are not enough to confirm a stair relocation. The relationship between the two storeys is particularly important, including any offsets that are difficult to understand from separate sketches.
Ask the designer to record floor-to-floor height, relevant ceiling and roof forms, door positions and known structural elements. These are inputs for professional design, not a set of dimensions for the homeowner to use in constructing a stair.
Include the thickness and intended finishes of adjoining floors. S&A Stairs’ design resources highlight the importance of coordinating adjacent floor finishes with stair design. A layout assessed against bare structure may need adjustment once the finished levels are established.
Mark the old stair opening as well as proposed new positions. Relocation creates work at both places. The former opening may become useful floor area, but its reinstatement and the room arrangement around it need to be designed and priced.
Draw the complete space used by each option
A stair symbol often represents the walking surface without fully showing the surrounding construction. Ask for the width of the assembly, barriers, handrails, supporting elements and enclosing walls to be reflected in the concept. Otherwise, the apparent spare space can disappear during detailing.
The floor opening also needs to be shown separately from the stair footprint below. It may extend over a different area to provide the required relationship between the stair and the upper floor. A plan that shows only the steps can conceal that consequence.
S&A Stairs’ resources also discuss how handrails and surrounding details affect usable width, and how entry and exit points interact with traffic. Use those considerations when reviewing a concept, while leaving the actual dimensions and compliance assessment to the project professionals.
Ask for furniture on both plans. A sofa, dining table, bed or wardrobe can reveal a conflict that an empty room disguises. Show doors in their operating positions and identify the routes people use when those doors are open.
Compare the main layout families in your actual house
A straight flight
A straight arrangement can provide a clear route and a simple visual connection between levels. Its length may, however, consume a substantial portion of a room or corridor. The important question is where that length sits and how people approach each end.
Check the upper arrival carefully. A stair running neatly beside a downstairs wall may arrive in the centre of an upstairs room. The resulting landing and corridor can cost more usable area than the ground-floor drawing suggests.
A stair that turns through the plan
A turning arrangement can distribute the stair across a different shape of space. The turn might work around an existing wall or align the upper arrival with a corridor. It also introduces a change of direction that needs to be designed for safe, comfortable use.
Ask the designer to compare a landing arrangement with any other proposed turning geometry rather than treating them as interchangeable symbols. The household’s needs, available space and applicable requirements should inform the choice.
A return arrangement
A stair that doubles back can concentrate the connection within a more compact-looking zone. That may suit a central position, but the whole assembly, landings and opening still require room. It should not be assumed to save usable floor area until both levels are measured and furnished.
Consider how the return affects sightlines and movement. The downstairs entrance may face one direction while the upstairs exit faces another. This can be helpful for privacy or awkward for circulation depending on the rooms around it.
Use sections to resolve headroom and vertical conflicts
A floor plan cannot show all the constraints above a person using the stair. Ask for a section through each serious option showing the stair, upper floor, ceiling, roof form and any relevant beam. This is often where a promising plan reveals its main difficulty.
The designer and stair specialist should assess headroom throughout the route using the requirements applicable to the project. Do not rely on the height at only the bottom or top. A sloping roof, floor edge or structural member can affect an intermediate part of the ascent.
Check adjoining uses beneath the stair in the same section. Storage, a doorway or another circulation route may need clear height that the concept does not provide. Space that exists in plan can be unsuitable for the intended function once its vertical shape is understood.
If an option requires moving a beam, altering a roof or changing floor construction to obtain headroom, identify that as a major design dependency. It should be assessed before the option is described as a simple relocation.
Trace daily routes through both floors
Walk through the proposed house on paper. Start at the front door, move to the kitchen, carry laundry upstairs and return to the bathroom at night. Consider what happens when two people travel in opposite directions or a bedroom door opens onto the route.
For more detail on this part of the project, see Moving a Laundry Upstairs: Floor Support, Vibration and Leak Containment.
Count the circulation that exists only because of the new stair position. A short stair route can still require a long upstairs corridor. Conversely, an option using slightly more stair area may allow several rooms to connect directly and make the rest of the plan more efficient.
- How does a person approach the first step?
- Where do they stand after reaching the top?
- Which doors open into the arrival or departure area?
- Does traffic cross a cooking, dining or work zone?
- Can bedroom privacy be maintained?
- Can furniture be moved through the proposed route?
- Are essential facilities accessible if part of the house is closed?
Use your actual furniture and routines where possible. A drawing labelled bedroom may have little usable wall space after a new doorway and corridor are introduced. A living room may gain floor area yet lose the only sensible position for seating.
Compare usable area rather than the stair footprint alone
Record the area gained at the former stair location, the area taken by the new stair and any additional circulation on both floors. Then consider whether the remaining spaces have useful shapes and access. A small rectangular gain may be more valuable than a larger awkward corner.
For illustration, suppose one hypothetical option releases 6 square metres downstairs but uses 4 square metres of new stair area and 3 square metres of additional upstairs circulation. The simple arithmetic is a net loss of 1 square metre across the house. Those assumed areas do not determine compliance or value; they show why measuring only the released space is misleading.
Another option might produce no net area gain but improve room proportions and privacy substantially. The comparison should therefore include function as well as area. Do not reduce the decision to a single number if the household benefit lies in a more useful plan.
Ask how the old opening will be finished. Matching floor levels, ceilings and finishes can influence whether the recovered area becomes a seamless part of a room or remains visually awkward.
Identify structural and service dependencies early
The proposed opening and the closure of the old opening need professional structural assessment. Your Home’s renovation guidance calls for appropriate engineering when structural modifications are designed. The stair manufacturer’s assembly design and the building’s supporting construction should be coordinated explicitly.
Map known services near candidate positions. A new opening may conflict with plumbing, ventilation ducts, electrical routes or equipment. The relevant trades and designers should assess relocation requirements and whether an alternative stair position avoids unnecessary work.
Do not rule an option in or out solely from a visible wall thickness or a guess about joist direction. The professional assessment may require records, inspection or controlled investigation. Note the uncertainty and arrange the appropriate next step.
Include any effect on fire safety, separation, access or other requirements relevant to the building. The applicable rules depend on the property and jurisdiction, so the building approval professional should confirm the pathway and assessment needed.
Review daylight, noise and privacy around the new opening
A stair opening connects spaces visually and acoustically. Moving it can change how sound travels between living areas and bedrooms, or how light reaches an internal zone. Ask the designer to discuss those effects alongside the floor plan.
An open arrangement may improve sightlines but expose private areas to the entrance. An enclosed stair may provide separation while making a nearby room feel more confined. These are design trade-offs to evaluate in the actual house rather than assumptions that one style always feels more spacious.
Plan lighting as part of the route, including how occupants operate it from relevant positions. A decorative fitting should not become the only means of seeing the stair clearly. Electrical design and installation belong with the appropriate professionals.
Consider future use too. If the reason for relocating is to improve long-term access, ask whether the proposal genuinely addresses that need or simply creates a more attractive stair. Essential rooms on one level or a separately assessed lift option may need consideration.
Make an option sheet before selecting the location
For each serious candidate, include plans of both levels, a section, the main benefits, affected rooms, structural and service questions, approval assumptions and a preliminary cost scope. Record what is confirmed and what still needs investigation.
Ask the builder to price the surrounding work as well as the stair assembly. The comparison should include opening changes, reinstatement, service alterations, finishes and temporary access arrangements. A cheaper stair product does not necessarily make the overall location cheaper.
Test the construction sequence at a high level. Determine when the existing stair would become unavailable and whether the home could remain occupied safely. The responsible professionals should plan temporary access and protection; household improvisation should not be part of the option’s claimed saving.
Choose a location that remains convincing after the detail is added
The strongest option is one that still works when walls, handrails, finished levels, furniture, landings and structural requirements are shown. It should improve the house in a way you can describe clearly, while keeping the unresolved conditions manageable.
Once the position is selected, coordinate the detailed design before manufacture or building work begins. Keep changes to floor finishes and adjoining rooms connected to the stair documentation. A successful relocation is the result of making the entire route fit the home, on both levels and through the space between them.
