What affects the cost of staircases?
Various factors influence the final cost of a staircase for a loft conversion. These include design, materials, dimensions, the location of your house, and others. Understanding all these factors can help you make informed decisions and budget accurately for the project.
Let’s dive in.
Design and materials
- Complexity of design: A more complex staircase design, including custom shapes, elaborate railings, or unique features, can elevate the cost by 10–30%. Custom designs require more planning, labour, and sometimes specialised materials. This contributes to the overall increase in expenses.
- Adding a door: Installing a door at either the bottom of the first-floor landing or the top of the staircase for added privacy also impacts costs. This modification involves additional materials and labour. Prices for basic standard interior doors start from around £100.
- Materials used: The choice of materials significantly affects the price. Wood is a popular option due to its versatility and warmth, but metal and glass are also common for their modern appeal and durability. Wood is generally the most affordable material, followed by metal, with glass typically being the most expensive due to its processing and safety features.
- Dimensions: The height and width of the staircase are crucial factors. Larger dimensions mean more materials, more labour work, and possibly more complex structural support, thus increasing the cost.
Location of stairs
- Space availability: The area where the stairs will be installed plays a crucial role. Limited or complex spaces might require custom work on loft conversion stairs for small landings, increasing the cost.
- Disposal of old stairs: If the project involves replacing existing stairs, removal and disposal add to the overall expenses, potentially increasing costs by 5–10%. On average, skip prices start from approximately £200 to £250, depending on your location.
Building regulations
Building regulations in the UK set specific standards for staircase design in loft conversions to ensure safety and accessibility. While you may not need to obtain a Planning Permission, following these building regulations is absolutely essential.
Here are some key regulations and how they might affect the cost:
- Minimum width: Staircases must have a minimum width of 600mm for loft conversions, but ideally, they should be at least 800mm wide. Narrower staircases could result in non-compliance, potentially leading to the requirement to rebuild the staircase according to the regulations.
- Maximum rise: The maximum rise for each step is 220mm. Staircases that require smaller rises to accommodate height restrictions may need more steps, potentially increasing costs.
- Minimum going: The minimum going (depth) of each tread must be 220mm. More depth can mean a longer staircase, requiring more materials and space, thus affecting the cost.
- Headroom: There must be a minimum of 2m headroom throughout the course of the staircase. Achieving this in a loft conversion may require structural alterations, impacting the budget.
- Pitch of the staircase: The pitch, or angle, of the staircase should not exceed 42 degrees. Steeper staircases may save space but compromise comfort and safety, possibly requiring redesigns to meet regulations.
Adhering to these regulations may necessitate design adjustments, such as increasing the staircase's footprint or incorporating additional steps, both of which can raise the project's cost. Moreover, non-compliance detected during or after construction may result in costly modifications or penalties.
With the Building Safety Act effective from October 2023, compliance with building regulations for loft conversion stairs has become even more crucial. This Act, motivated by enhancing safety and quality in the construction industry, introduces severe penalties for violations, including unlimited fines and up to two years of imprisonment.
As Clair Phillips, a lawyer at Moore Barlow, explained, The Act significantly increased the penalty for breaching building regulations. Earlier, the fine was a maximum of £5,000, and now it is an unlimited fine and/or imprisonment of up to two years.
It's a clear signal that adherence to the minimum standards for staircases — width, rise, tread depth, headroom, and pitch — is mandatory to avoid penalties and ensure safety.
Direct costs associated with meeting building regulations (such as application fees for approval) are relatively minor compared to the overall project budget. They are determined by each local council and can depend on factors such as the size and complexity of the project.
It's common for the fees to be structured into a scale that reflects the level of inspection and certification required. But generally, they fall within a few hundred pounds.
Still, the implications of these standards on design and construction can significantly affect total expenses. Ensuring that the staircase design complies with these regulations from the planning phase can prevent unexpected costs and project delays, making it a wise investment.
How much does a loft conversion with stairs cost?
The cost of stairs for loft conversion varies widely depending on the type of conversion you choose. Here’s a breakdown to give you an idea of what to expect for each type:
| Loft conversion tуре | Estimated cost for 30m2 conversion | Estimated cost for 30m2 conversion | Total cost |
|---|---|---|---|
| Velux | £35,000 | £1,000 | £37,000 |
| Dormer | £40,000 | £1,000 | £41,000 |
| Hip to gable | £45,000 | £1,000 | £46,000 |
| Mansard | £60,000 | £1,000 | £61,000 |
Each type of conversion brings its unique characteristics, impacting both the loft conversion cost and the potential living space.
Velux loft conversion maintains the existing roofline, adding Velux windows to introduce natural light. It’s a less invasive option, ideal for lofts with ample headroom.
Dormer loft conversion extends vertically from the sloping part of the roof, creating additional headroom and floor space with a flat roof dormer. This is a popular choice due to the significant space it adds.
Hip to gable loft conversion extends the roof by replacing the sloping ‘hip’ roof with a vertical ‘gable’ wall, increasing the usable loft space. It’s particularly suited to semi-detached or detached houses.
Mansard loft conversion involves altering the roof structure to create a flat roof with the back wall sloping inwards, offering substantial space and flexibility in design.
In general, the most expensive part of a loft conversion typically involves the structural changes needed to make the loft a livable space. This can include strengthening the floor, altering the roof structure for more headroom, and installing windows or dormers.
Furthermore, the more structural changes loft conversion has, the bigger the possibility that this conversion requires Planning Permission.
That’s why loft conversion types that require more structural changes are the most expensive ones.
Those, who are eager to perform a budget-effective small attic renovation, often opt for space saving loft conversion stairs. These stairs often feature alternate-tread designs or steep and compact configurations that can fit into tighter areas than standard staircases. For off-the-shelf space-saving stair kits, prices might start from around £1,000 to £2,000.
Ways you can reduce loft conversion stairs costs
Reducing the costs associated with installing loft conversion stairs involves strategic planning and smart choices. Here are practical tips and strategies that can help manage and potentially lower these costs:
DIY with self-fit loft staircase kits
Self-fit staircase kits offer a cost-effective solution for those confident in their DIY skills. These kits come with all the necessary components and instructions.
However, if you decide to do it yourself, ensure you have the required skills and tools. Incorrect installation can lead to additional costs for repairs or professional reinstallation in the future.
Repurpose existing materials
Utilising salvaged or repurposed materials can significantly reduce costs and contribute to sustainability as well as give a charming appearance to your loft’s stairs.
Old timber or metal from renovations or demolitions can be repurposed for stair construction, given they meet safety standards and regulations.
Timing and seasonal discounts
Contractors' schedules can influence project costs. Off-peak seasons or slower periods for business might offer an opportunity for discounts. Plan your project during these times to negotiate better rates.
According to Legal Eagle Contractors, the colder months are typically less busy for renovations. Many people focus on indoor activities and holiday preparations, reducing the demand for construction services. During this time, contractors may offer discounts to keep their teams busy.
Renovation in early spring and late fall may also be cost-effective. Justin Goldman, the CEO and co-founder of RenoFi and expert in home equity loans, says that just before and after summer are also times when demand dips slightly. Contractors finishing up projects may be willing to negotiate on price to secure their business before the slow season or to extend their active season a bit longer.
Alternative, cost-effective materials
Exploring alternative materials that are both durable and cost-effective can reduce overall expenses.
For example, softwoods like pine are generally less expensive than hardwoods but still offer durability. Engineered wood products or certain metals might also provide budget-friendly options without compromising quality.
