Introduction to loft conversions
For those who are new to the world of home extensions, we'll start with the basics: what is a loft conversion, and why should you consider one for your Glasgow home?
A loft conversion is the process of transforming the unused loft space in your home into a functional living area. These extensions can be crafted to suit your unique needs and preferences but typically involve adding flooring, insulation, windows, and stairs, among other elements, to create a new room (or rooms) within your existing house.
They offer several advantages that make them a popular choice among homeowners:
Maximising space: By making use of space you already have, they maximise the potential of your existing property, so you can avoid moving home.
Cost-effective: These extensions create valuable extra room, but can be easier to accommodate and less expensive than some other types of house extensions.
Value-adding: They can significantly increase the market value of your home. Note: compare similar-sized properties in your area to get a sense of how much value you could add.
Bespoke design: Converting unused storage space in your attic is a great way to create more useful space that's tailored to your individual needs and preferences.
Natural light: With strategically placed windows and skylights, these light-filled spaces make fantastic extra bedrooms and home offices.
Now that you have a basic understanding, let's move on to the various types of loft conversions available to homeowners in Glasgow and the wider UK.
Different types of loft conversions
There are a variety of different types of loft conversions, each with distinct features and advantages. Deciding which type of loft conversion to create depends on certain circumstances. These include your home's structure, your budget, and your design preferences. Here are some of the most common types:
1. Roof light or Velux loft conversion
A roof light or ‘Velux’ loft conversion is one of the most cost-effective and straight-forward types of home extension. With this basic loft conversion approach, the existing roof structure remains largely unchanged, but roof lights are added to bring in natural light. Velux loft conversions are ideal for homes with a deep floor plan and a steeper roof pitch.
Converting the interior of your attic into living space
In addition to adding roof lights, you will also need to fit-out the interior space. This process includes insulating the attic area, lining it with plasterboard, and strengthening and upgrading the attic floor. This will become the floor of your new room, so the latter is important for acoustics as well as stability.
Velux loft conversion cost
Keep in mind that while a Velux loft conversion is the most budget-friendly option, you will be limited by the constraints of your existing space. For more information on costs, please see our FAQ below.
2. Dormer loft conversion
For homeowners who need more space and have a larger budget, a dormer loft conversion is another popular choice. The work involves removing part of the roof to expand the usable floor area and create more headroom. Dormers also offer more glazing options, in the form of dormer windows, and can significantly improve the layout and functionality of the space.
Do I need planning permission for a dormer loft conversion?
It's important to note that, depending on their size and location on the house, obtaining planning permission may be required for some dormer extensions. While rear dormers are generally easier to get approved, front-facing dormers, especially in conservation areas, can be more challenging.
3. Hip to gable loft conversion
Hip to gable loft conversions are most suitable for semi-detached houses where the attic's most significant head height is often not above the circulation space. By changing the hip of a roof into a gable, this type of conversion adds more usable space and floor area. Although this type of conversion can be disruptive, it can also be worthwhile due to the additional space provided.

Cost of a hip to gable conversion
The cost of a hip to gable loft conversion is generally similar to that of a dormer conversion, but this will vary based on the project's specific design and requirements.
4. Mansard loft conversion
Mansard roofs are less common in the UK, but they can be used in some contexts. A Mansard loft extension involves removing the entire roof and constructing a new one, either in a Mansard shape or a similar shape to the original but with slightly adjusted pitches or a different profile. While full Mansard roof extensions are rare due to planning permission, full-roof replacements achieve a similar purpose in a slightly different shape roof.

While a Mansard loft extension (or full-roof-replacement as it is also known) is the most disruptive and costly option, it does offer the most substantial benefits in terms of enhancing space and functionality. Ideal for homeowners with larger budgets seeking maximum space, these projects require significant planning considerations.
To gain a better understanding of the average loft conversion cost for your particular project, consult with an expert who can provide a detailed estimate based on your specific needs.
Project example: maximising loft space in a Glasgow home
For a deeper look at the full-roof-replacement loft conversion process, you can read about our Bearsden bungalow roof extension project. Here our loft conversion specialists helped a Glasgow family create dramatically more living space by maximising the potential of some unused garden space at the side of their detached property and completely replacing the bungalow's roof. The result? A beautiful new attic space that includes a master bedroom with en suite, multiple new bedrooms with dormer windows, and significantly more space downstairs for family living.

Loft conversion cost breakdown
There is a considerable amount of variability in the cost of an attic conversion and this is dependent on the type of extension you choose to go with, the extent of any structural changes that are required and the size parameters of your space. Here are some key considerations:
Construction costs:
Construction is typically the most significant expense in a loft conversion project. Costs will vary based on the specific design and project requirements.
Architect fees:
Architectural fees cover work undertaken during the design and planning stages of the project. Working with an architect in the early stages will help you maximise your property’s potential and ensure you achieve your goals in the most efficient and cost effective way.
Structural engineer fees:
Structural engineers play a crucial role in ensuring the loft conversion is structurally sound. Their fees are part of the overall cost.
Planning application and building warrant fees:
Depending on your location and project specifics, you may need to pay fees for planning applications (if your build falls outside of permitted development) and a building warrant.
Budgeting tips:
To manage your budget effectively, consider consulting with a builder early in the design process. They can provide initial estimates to help you make informed decisions about your project. Consulting with multiple loft conversion companies in order to compare quotes and services can help you determine which provider offers the best fit for your needs.
It's also important to assess the final value a completed loft conversion will add to your home by researching similarly sized properties in your area, especially if you plan to finance the project through a mortgage.
Loft conversion planning permission and building regulations
Before embarking on your loft conversion project, it's crucial to understand the planning permission and building regulations that may apply. Here's what you need to know:
Permitted development:
Permitted development regulations outline changes you can make to your home without requiring planning approval. However, you will still need a building warrant. Be aware that permitted development rules don’t apply to conservation areas or flats. Consult with an experienced architect familiar with local planning policies to be clear on what is possible for your individual project.
Planning permission for a dormer loft conversion
Dormers, which add the most usable floor space and headroom, can sometimes be restricted in terms of planning approval. For most loft conversions, rear dormers are generally allowed, however, front-facing dormers, especially in conservation areas, will require permission.
Timeframe:
Planning departments typically aim to respond to applications within six weeks, though it often takes longer. Be prepared for the design and application process to take around six months in total.
Structural analysis
The structural integrity of your extension is paramount. While structural design is primarily the responsibility of a structural engineer, architects play an important role in considering how changes to the existing structure will impact the project's cost and feasibility. Your architect can identify where heavy construction work is genuinely necessary in the early stages of your project and help to optimise those areas. This means you’ll avoid unnecessary expenses, ensuring your project progresses in the most cost-efficient way.
Form and function in loft conversion design
As discussed, creating an effective and aesthetically pleasing new loft space involves balancing various factors. These include aspects we’ve mentioned above, like structural impact and compliance with planning policies. However, details like head height and insulation also influence the design process and it’s worth saying a bit more about those here.
Head height in your loft space
Head height is an essential consideration, particularly in roofline or 'Velux' loft conversions where the existing attic's limitations constrain the new space. However, head height remains relevant across the various attic extension types.
In many projects with smaller or average-sized attic spaces, the area beneath the roof's ridge typically offers the most headroom. However, building regulations emphasise adequate headroom on staircases. Consequently, staircases are often placed in the middle of the floor plan, impacting both the upper attic space and the floor below.
Effective staircase placement
Central staircase placement can limit usable space and therefore requires thoughtful consideration in advance to optimise the new loft room. Additionally, the staircase's location can affect the lower level's layout, necessitating a balance between gaining new space upstairs and maintaining functionality on the floor below. Loft conversion stairs should ideally connect to existing circulation spaces. Architects can help plan staircase placement effectively.
Other implications for your project
Keep in mind that having an early understanding of structural and head-height dynamics is crucial for creating successful loft conversion plans and can impact your budget. Additionally, be aware that for projects with occupants residing in the house during conversion, minimising roof disruption is essential.
Improving energy efficiency with insulation
Many people who convert their attics to provide additional space in their homes find they also achieve the added benefit of improved energy efficiency. Expanding your home's habitable space means you’ll need to meet current building regulations. U-values for the building fabric in the new roof and its surroundings are a significant part of the necessary energy calculations.
Architects consider compensatory energy calculations when they design. This allows them to preserve head height in key areas by reducing insulation in one area and adding extra insulation elsewhere to compensate.
Glazing in your attic space
The introduction of glazing can bring valuable natural light and even beautiful views to your space. Your architect will help to balance these benefits against thermal performance requirements. This process helps to ensure that your new extension excels in aesthetics, functionality, and energy efficiency, providing a comfortable and sustainable living space.

FAQs
How much does it cost to get an architect's drawings for a loft conversion?
Architectural fees for loft conversion drawings can vary based on several factors:
Measured survey: An architect’s fees typically include a measured survey of your existing house. Depending on the size and complexity of your property, the price of a measured survey will normally range from £900-£1,400.
Outline proposal drawings: Influenced by the clarity of your vision, the overall size of the design, and the technical complexity of the project, proposal drawings range in price from £200-£1,100.
Building warrant: The type of loft conversion project you choose, whether a Velux conversion or a complete roof replacement, affects the expenses related to building warrant submissions and architectural design. A building warrant application will range from £1,100-1,500 depending on complexity.
Is it worth hiring an architect for a loft conversion?
Hiring an architect for your project has many benefits. Architects provide expertise in understanding your project's priorities and offer solutions tailored to your lifestyle and property. They guide you through the planning process and help navigate the complexities of planning permission and permitted development in your specific area.
Having the input of an experienced loft conversion architect in Glasgow, or other location, ensures that your new space aligns with your vision, maximises functionality, and complies with necessary regulations.
How much does a loft conversion cost in Glasgow?
The cost of a loft conversion project primarily depends on two key factors: the extent of changes made to the existing structure of your building and the size of the attic space you are creating.
Project types range from budget-friendly options like roof light or ‘Velux’ conversions to more extensive projects, including dormer conversions or complete roof replacements. The size and complexity of the project will significantly impact the overall cost, with larger and more intricate projects generally incurring higher expenses.
How much does a dormer loft conversion cost in Scotland?
Dormer loft conversions in Scotland vary in cost based on several factors. One of the primary considerations is the size of the dormers, particularly their width. Smaller dormers, especially traditional-style ones, require less structural work and tend to be more budget-friendly. In contrast, larger dormers that span the full (or nearly full) width of your property involve more extensive structural interventions and typically fall at the upper end of the price spectrum for dormer conversions. The cost also depends on the specific requirements and design preferences for your project.
