Via delle Quattro Fontane 33, Rione Trevi
Every month we pick one property and study it to the ground — what it's worth and what needs fixing. We chose this one because, once all the numbers are in, it adds up.
Why this lot
A building site abandoned for thirty years, three hundred metres from the Quirinal Palace, with an 18th-century timber ceiling still in place and five bathrooms nobody ever finished using. The base price works out at €2,700/sqm in a micro-zone the Revenue Agency values between €6,600 and €9,200. We study it in full — including everything that does not add up.
Executive summary
A 165 sqm apartment on the first floor of an 18th-century building on Via delle Quattro Fontane, Rione Trevi. An abandoned building site at roughly 20% completion: no finishes, no floors, no doors or window frames, services barely started. It retains an 18th-century timber ceiling, a marble and wrought-iron entrance hall and a private rear courtyard.
This is a high-risk lot and we are not hiding it: the structure of the building was compromised in 1991 by works in the ground-floor shop, the strengthening works begun in 1996 were never signed off, and the civil claim that followed is still pending.
Lot fact sheet
How and when it is sold
Location and context
Rione II Trevi, OMI zone B31 (Tridente / Colonna / Trevi). This is the quarter between the Quirinal and Piazza Barberini: government offices, historic hotels, steady visitor traffic all year round.
Real distances
- Piazza Barberini~280 m
- Quirinal Palace~300 m
- Via Nazionale~400 m
- Trevi Fountain~450 m
- Repubblica metro station~500 m
Condition of the property
Site visit of 6 March 2026. The property is an interrupted building site: no finishes, no floors, doors and window frames absent, services barely laid in. Completion is estimated at around 20%.
What remains, however, is not something a refurbishment could recreate: the 18th-century timber ceiling, the marble and wrought-iron entrance hall, the rear courtyard. You buy those with the property or you do not have them at all.


The proposed use: guest house in Rione Trevi
The five bathrooms built against the two on the register are not simply a breach to be undone: across two rooms, they are the trace of a hospitality project started in the 1990s and never finished. The court expert's own report notes the area's hospitality vocation. What we propose is not changing the use of the property — it is finishing what somebody else began.
Five bathrooms already built
165 sqm, 7 rooms, 5 bathrooms against the 2 on the register. Plumbing is the single most expensive item in a guest house and it is already in place: you are not starting from a flat, you are starting from a stalled hospitality project.
Private rear courtyard
A private open space is rare in Rome's historic centre. It is what separates one property from every other on the same street.
18th-century timber ceiling, marble and wrought-iron entrance hall
These set the nightly rate, not the floor area. No refurbishment can add an original 18th-century ceiling: either it is there or it is not.
Everything on foot
The Quirinal 300 m away, Piazza Barberini 280, the Trevi Fountain 450, Repubblica metro 500. In the centre a guest house is measured in minutes on foot.
This use is proposed, not established. The three checks below are blocking: until they are closed the Exit B figures have no basis, and this section should be read as a working hypothesis, not an approved project.
Three blocking checks, before any bid
Do the building's rules of association allow hospitality use?
Priority check with the building manager. Historic building with pending civil claims: a prohibition in the rules would make the whole intended use unworkable, and Exit B with it.
Roma Capitale rules on short lets in the historic centre
The rules on short lets in Rome's historic centre are changing. The regulation in force at the date of the transaction must be established, not the general position.
Requirements for guest-house classification and the CIN code
Structural and health requirements for classification, the hospitality SCIA permit and the national identification code (CIN).


Planning and building issues
In order of severity, not of convenience. The first two are outside the buyer's control and are the reason this lot is classified high risk.
1991 — structure compromised, claim still open
Works carried out in the ground-floor shop compromised the structure of the building, with documented cracking. The civil claims that followed are still pending. It is the most serious issue on this lot and it is not within the buyer's control.
From 1996 — partial structural works, never signed off
The structural works started in 1996 were only partly completed and were never signed off. Until they are, the true extent of the remaining work stays an estimate.
Five bathrooms built, two on the register — regularisable via SCIA
The main discrepancy between the filed floor plan and what is actually there, and one that can be regularised through the ordinary process. It is also the reason this property is worth more than it looks: see the section on intended use.
Altered windows and service rooms — to be reinstated
Works that cannot be regularised: they must be demolished and reinstated to the lawful state, at the buyer's expense.
Criminal exposure for the 1991/96 works: time-barred
The offence relating to the 1991 and 1996 structural works is time-barred. The planning and civil issues remain; the criminal one does not.

Why our exit sits below the best listings
Pushing the value down
- First floor above the shops. The best comparables are on the fourth and fifth floors with a lift and a view: in central Rome the premium for upper floors is substantial.
- The documentation shows no lift in the building.
- Via delle Quattro Fontane is a through route between Barberini and Santa Maria Maggiore: traffic and buses. The Piazza Scanderbeg listing explicitly sells the opposite, «set apart from the tourist crowds».
- Structural strengthening works from 1996 that were never signed off, and a pending civil claim: an informed buyer prices both in.
Pushing the value up
- 36 sqm of terrace plus the private courtyard. In the historic centre private outdoor space is rare and commands more than its proportional share of the floor area: it is the single most valuable feature of this property, and it had been overlooked.
- 18th-century beamed ceilings in several rooms: on a high-end restoration these are what justifies the top price.
Financial analysis
The court expert estimates €260,000. We obtained a quote from a building firm with a track record in central Rome: €180,000 plus VAT — a preliminary quote, pending the detailed specification.
What it costs, line by line
- VAT: renovation works are taxed at 10%, but «significant goods» (window frames, boiler, sanitary ware) qualify only up to the value of the labour, and the excess is taxed at 22%. Hence roughly €202,000 on a net €180,000.
- Professional fees: site supervision, safety coordination, the SCIA filing, regularisation of the planning breaches and the final land-registry work. None of it is included in the builder's quote.
- Purchase costs: registration tax or VAT depending on the applicable regime, the delegated professional's fee and transfer expenses. The amount depends on the judge's transfer decree.
- Contingency: on an 18th-century building this is standard practice, not pessimism.
Exit scenarios
Margin on the investment ~€ 620.000 – 645.000
Two exits, not one
Selling the refurbished property
You realise the margin in one go: design, works, regularisation and sale of the finished property.
Assuming the lot is awarded at the minimum bid.
Letting it as a guest house
You keep the property and make it earn as a guest house. Management does not fall on the investor: it passes to Gestione Casa Vacanza, the group company that has run short lets in Rome for over ten years. Furnishing, paperwork, listings, bookings, check-in, cleaning and maintenance.
Why yes, why no
Why yes
- One of the most prestigious locations in Rome, a short walk from the Quirinal Palace
- Heavily discounted auction price: ~€2,700/sqm against €6,600–9,200/sqm locally (OMI B31)
- Private courtyard/terrace, rare in the historic centre
- The property is empty: there is nobody to physically remove
- Main discrepancies regularisable via SCIA, already budgeted
- Five bathrooms across two rooms suggest an unfinished B&B project, consistent with the area's hospitality vocation noted by the court expert
Why no
- A building site, not a home: no warranty against hidden defects, costs only estimated
- The 1996 structural works are partial and were never signed off
- A civil claim is still pending over the 1991 structural damage
- Formal release is still under way: time and cost are not quantified in the court report
- Works that cannot be regularised must be demolished and reinstated at the buyer's expense
- Permits and construction in the historic centre / restricted traffic zone: typically 18–24 months or more
Methodology note
This page draws on four sources, and every figure states which one it comes from. Lot data, planning breaches and the expert's estimates: the sworn court valuation under art. 568 of the Italian Code of Civil Procedure and the Ministry of Justice auction portal. Local values: the Italian Revenue Agency's property market observatory (OMI), micro-zone B31, plus sale listings surveyed in the same micro-zone (asking prices, not recorded sales). Cost of works: a preliminary quote from a building firm with a track record in central Rome. Fees, contingency, exit scenarios and margins: My Dear Italy's own workings on the above. Those workings are estimates, not guarantees: the exit value depends on the quality of the restoration and on the market at the time of resale.
This is one lot.
