Loft Conversion Feasibility
We look at the roof shape on your property, the loft headroom we can infer from your floorplan, the planning history of your immediate street, and any conservation or Article 4 constraints. Then we give a single-sentence verdict: dormer is realistic, hip-to-gable is the move, L-shape is your goldmine, or honestly, don't bother. With cost bands and the planning route attached.
- I keep being told "you could convert that"
- I'm weighing up loft vs extension
- I want a third bedroom without moving

Visualised on your property
Dormer, hip-to-gable or L-shape; what your loft can become and what it would cost.
Three estate agents have told you the loft "would make a brilliant third bedroom". You climbed up in October and stood there in the dark wondering if your head would actually clear the ridge. The architect down the road quoted £600 just to come and tell you what your council probably won't approve. The Loft Conversion Feasibility report tells you that today, in plain English: dormer, hip-to-gable, L-shape or no-go, with the actual planning approvals from your street as evidence and a cost band attached.
What you actually get
Six concrete things inside the report.
Not a generic guide. These are the specific deliverables we ship for your address, every single time.
A clear verdict on viable conversion types
Roof-light only, rear dormer, hip-to-gable with dormer, or full L-shape. With the reasoning, not just the label.
Neighbour precedent on your street
Every loft conversion approved within a few hundred metres in the last 5 years, with addresses, dates and what was built. The "no. 28 got this approved in 2019" evidence that wins arguments.
Planning route: PD vs full application
Whether the verdict route falls under Permitted Development for your house type, or whether it needs a full planning application. Including Article 4 and Conservation Area flags.
Cost band for the recommended option
Honest UK pricing for the type of conversion we recommend, broken down by structural work, fit-out, en-suite if relevant, and the things specialists tend to hide.
Value uplift band for a home like yours
What a well-done loft typically adds to a home in your price bracket and your postcode. With caveats; not a single magic number.
Built from this data
Grounded in the actual evidence of your property.
Every recommendation in the report ties back to one of these data streams. No generic Wikipedia summaries; no postcode averages.
Your roof shape and loft footprint
Inferred from the floorplan, the aerial view and the elevation in your listing photos. Headroom estimate plus the type of conversion the roof can physically accept.
Planning history within 500m
Every loft conversion decision near you - approved, refused or withdrawn - read for patterns. Local precedent matters more than national rules.
Planning constraints on your plot
Conservation Area, Article 4 direction, listed status. The hard limits that decide whether PD even applies.
What it looks like
A glimpse of the report itself.
The full report lands as a single scrollable page. Visualisations sit alongside the costs, planning verdicts and value uplift, so you can argue with it (or with your partner) in one place.
Visualisation for this property
Converted loft bedroom with painted beams, dormer window and warm neutral linens.
The verdict (one sentence)
Dormer, hip-to-gable or L-shape; what your loft can become and what it would cost.
Likely value uplift
Typically +£40k to +£80k
Cost & value
What it costs. What it adds.
Honest bands tuned to UK pricing in the last 12 months, plus a value uplift range for homes in your bracket.
Strongly correlated with adding a usable bedroom and an en-suite. Lofts that are just "more living space" tend to add less than ones that bump the bedroom count.
The fine print, up front
What this report does not cover.
A clear list of what we leave out, so you never feel short-changed when you open it.
- Structural engineering calculations (this report sets you up for the engineer, it does not replace one)
- A guaranteed planning verdict from your council (we tell you what your council has approved nearby, which is the best signal available pre-application)
- Interior design for the new room (the Kitchen / Bathroom reports cover the rooms; this report focuses on whether the loft can be built at all)
If we can't make this report outstanding for your address, you don't pay.
If we can't find the photos, planning history or constraints we need to make this specific report genuinely useful for your house, we refund the full price before generating a single word. Same goes if you read it and it just doesn't deliver.
