Transforming your loft is one of the smartest ways to unlock space, increase property value, and avoid the stress and cost of moving.
But not all loft conversions are created equal and choosing the right type for your home is crucial to maximising your investment.
At Excellence Living, we guide homeowners from concept to completion, helping you make the best choice based on your home’s structure, budget, and lifestyle goals.
A Dormer conversion adds a box-like structure to the roof, creating vertical walls and a flat ceiling. This significantly increases floor space and headroom—ideal for adding a full bedroom, office, or even a bathroom.
Typical cost: from £45,000 – £55,000
If you’re looking to add an entire new storey to your home, Mansard conversions are the most transformative. These involve major structural changes—flattening the rear roof with near-vertical walls and adding dormer windows.
Typical cost: from £60,000 – £75,000
This method converts a sloping “hip” roof into a straight vertical wall (“gable”), creating extra loft space across the full width of your home. Often combined with a rear dormer for maximum size.
Typical cost: from £50,000 – £60,000
The best choice depends on:
Don’t spend money on architectural plans until you’ve spoken with an experienced build team who can confirm feasibility and real-world costs.
Every successful loft conversion needs a little more than just structural work. Make sure you account for:
At Excellence Living, we provide full visibility on all costs – so there are no surprises down the line.

It depends on your home’s roof structure, existing loft space, and how you plan to use the new room.
At Excellence Living, we assess your property and goals to recommend the most effective solution — structurally, financially, and visually.
A good rule of thumb is:
But every home is different. That’s why Excellence Living offers free feasibility assessments — so you know what’s possible before committing to drawings or costs.
Mansard and dormer conversions typically deliver the highest return on investment — especially when they add a new bedroom, en-suite bathroom, or create a large, multi-functional living space.
These conversion types dramatically increase your home’s usable floor area, boost natural light, and allow for flexible layouts — all features that modern buyers actively seek and will pay a premium for.
But it’s not just about adding space — it’s about adding the right kind of space, thoughtfully designed and professionally executed to maximise your property’s resale appeal. That’s where Excellence Living makes the difference.
Unlike general builders who may treat loft conversions as just another job, we specialise in transforming underused lofts into beautifully designed, high-performance rooms that feel like they’ve always belonged. Our design-led approach ensures every inch works hard — not just visually, but structurally, financially, and functionally.
Plus, the added value isn’t only immediate. With Bristol property prices continuing to rise, your loft conversion becomes a compound investment — increasing your home’s market worth now, and continuing to grow with inflation over time.
Whether you’re looking to future-proof your home, create space for your growing family, or prepare your property for a stronger sale — Mansard or dormer conversions done right can deliver lifestyle rewards and real financial gain.
Velux (rooflight) conversions are generally the most affordable option, starting from around £30,000, as they require minimal structural change.
That said, the best value-for-money option often depends on what you need the space for.
For example, a dormer with an en-suite may cost more but adds more value — both to your lifestyle and your home.
Loft conversions are often the smartest and most efficient way to expand your home — and in many cases, they offer better value than traditional ground-floor extensions.
Here’s why:
At Excellence Living, we take your loft further. Our expert team knows how to convert even the most awkward roof spaces into beautiful, practical rooms that feel like a seamless part of your home.
The value uplift depends on how well the loft improves your home’s usability, layout, and long-term appeal to buyers — not just the square footage added.
Conversions that achieve 20–25% added value typically include:
At Excellence Living, we factor all of this into your design — creating loft conversions that don’t just add space but add true long-term value and modern comfort. It’s how we turn your investment into a space that grows with your home andyour property’s market potential.
