It will come as no surprise that many people are looking to create more space at home. Adding a room or making more room in the space you have is a sensible move which offers short and long-term benefits for homeowners. If you are feeling cramped or you feel that a lack of space is impacting your household’s happiness, converting unused loft space is a great idea.
Of course, when you convert a loft into a living area or bedroom, you not only make more space for your loved ones, but you also add value to your property. For many property owners, this is important, and for some, it is the most vital aspect of homeownership.

Add value, not just space
If you treat your home as an investment opportunity, adding space and value is crucial, and it is vital to know how much value you can add to your home. There are many ways to improve your home, but not all home improvements are the same.
Some home improvements make life more manageable, but they don’t add value over and above the cost of the work. Therefore, if your main focus is on adding value to your property, you need to know how much value a loft conversion adds.

Loft conversions pay off
A study carried out Nationwide suggests that a loft conversion, creating an additional bedroom with en-suite facilities, adds an average of 21% to the value of your home. This is an appealing figure, but you must consider the cost of the project and the inconvenience the work causes. However, if you do the sums and you find you have a good return on your investment, you can feel confident about the project.
If you are looking to create more space around the home, take the following steps:
Review all your options
Loft conversions are popular, but they aren’t the only way to extend the size of your home. Speak to experts in this field, and if you have any friends, family members or colleagues who have had similar work carried out, ask them for recommendations.
Is your loft suitable for conversion?
Before you begin, it’s important to check if your loft is suitable. You’ll need enough head height, ideally around 2.25 metres from floor to ridge, and a decent footprint to make the space practical. The steeper the roof, the more usable space you’re likely to have. Traditional timber-framed roofs found in many older country homes are often the easiest to convert. Trussed roofs can still work, but they need more structural changes.
Know the rules before you build
Most loft conversions fall under permitted development, so you may not need planning permission. However, if your home is in a conservation area or the work changes the shape of the roof, you may need formal approval. Building regulations always apply to ensure the space is safe, well insulated and structurally sound.
What type of loft conversion suits your home?
The size and shape of your loft will often determine what kind of conversion is possible. If you have options, consider what suits your home best. Rooflight conversions are the simplest and most affordable. Dormers add more space and light, while also boosting property value. Mansard and hip-to-gable conversions involve more work but create generous, characterful spaces, ideal for larger or period homes. Choose the style that best fits your needs, budget and property.

How long does it take?
Most loft conversions take between four and eight weeks to complete. Rooflight conversions may take around four weeks, while more complex designs like mansards can take up to eight. Factors like weather, planning, and the condition of the roof can influence the timeline.
What will it cost?
The cost depends on the type and complexity of the work. A simple conversion with rooflights may start from £27,500, while a full conversion with a dormer or en-suite could cost £50,000 or more. A larger bungalow loft conversion could reach £75,000. It’s wise to get multiple quotes and include a contingency in your budget.
Where will your storage go?
While a loft conversion adds valuable living space, it often means losing your existing storage area. Items like suitcases, seasonal decorations or keepsakes will need a new home. Before work begins, think about where these things will go. Many builders can create clever storage solutions under the eaves or within built-in furniture, helping you make the most of the available space without compromising the room’s design.
Finishing touches and flooring
The right details bring your loft conversion to life. Choose simple, coordinated colours and soft furnishings to keep the space feeling calm and open. For flooring, options like wood, laminate or carpet all work well. Pick what suits the room’s use and your style, and consider professional fitting for the best result.
Design considerations for your loft conversion
A well-designed loft conversion balances practicality with comfort. If you’re adding a bathroom, plan for water pressure, drainage and floor strength early in the process. Your builder will need to incorporate these into the design from the start. The roof structure also plays a key role—cut roofs are easier to adapt, while trussed roofs need more work and support from a structural engineer.
Space is often limited, so use light colours, simple furniture and built-in storage to make the room feel larger. Maximising natural light with Velux or dormer windows can also open up the space. Just be aware of how this may affect neighbouring properties, especially if planning permission is required.

Check ownership, disruption and insurance
If your home is leasehold, you may not own the loft space. Always check your lease and get written permission from the freeholder before starting any work. Expect some disruption during the build—plaster, paintwork, or flooring may need repairing, and stair placement can be tricky. Allow for a contingency budget to cover any surprises. Also, notify your home insurer before work begins, as most policies require this to maintain coverage.
Getting the details right
- Position stairs above the existing staircase if possible, and plan plumbing routes early if adding a bathroom.
- Insulate well and install proper heating and lighting. Use blackout blinds in bedrooms and flexible lighting in workspaces.
- Add a clear focal point to anchor the room, like a feature wall or bold artwork.
- Get scaled plans from a designer to streamline approvals, quotes and layout decisions.
- Board and insulate walls for warmth, and fit permanent electrics and heating from the start.
Types of loft conversions to consider
- Dormer – Adds headroom and floor space by extending out from the roof. A versatile option for most homes.
- Hip to gable – Converts a sloping roof end into a vertical wall. Great for semi-detached properties.
- Mansard – A full-width extension with a flat roof and steep walls. Maximises space but usually needs planning permission.
- Velux – Simple and cost-effective. Adds skylights without altering the roof shape. Best where headroom already exists.
- L-shaped – Ideal for larger homes with rear extensions. Creates a spacious layout, often with two rooms.
- Pitched dormer – A dormer with a sloped roof, adding charm and character through internal angles.
- Side dormer – Brightens narrow lofts by bringing in light from the side, making the space feel open.
- Piggyback – Removes the existing roof and raises external walls. Adds a full extra floor but often needs planning permission.
