Renovating an apartment in Paris's 18ᵗʰ Arrondissement
A rental building on rue Caulaincourt, a former artist's studio near Abbesses, a family-sized three-room apartment close to Jules Joffrin: renovating a property in the 18th arrondissement is unlike anywhere else in Paris. Between the historic architecture, loft-style spaces under the eaves, and the protected heritage zone around Montmartre, every project brings technical decisions rarely encountered elsewhere in the capital.
As a specialist in bespoke, turnkey renovation in Paris, Maison Kyka designs, renovates, furnishes and delivers move-in-ready apartments throughout the 18th arrondissement. You receive the keys to a finished interior, designed around you, in one of the capital's most sought-after neighbourhoods. In this article, we explain what the building stock of the 18th arrondissement means for a renovation project, what budget and timeline to expect, and how a renovation with a single point of contact actually unfolds.
What the 18th arrondissement's architecture means for a renovation
Before the plans are even drawn up, it's the buildings themselves that set the rules for renovating an apartment in the 18th arrondissement. Three main building types coexist across the district, and each calls for a different approach on site.
Late 19th-century rental buildings
Most of the period buildings in the 18th arrondissement date from the second half of the 19ᵗʰ century. They offer generous ceiling heights, rarely consistent from one room to the next, wood flooring, and partition walls that are usually non-structural, leaving real freedom to reconfigure the layout. On the other hand, the electrical and plumbing networks have often aged without regular upkeep. That's why a full renovation always begins with a precise survey of the existing structure: it determines what can be opened up, moved, or kept as is.

Artist's studios and loft spaces under the eaves
The 18th arrondissement holds a rare architectural heritage of former artist's studios, a legacy of the era when Montmartre was home to countless painters. Original skylights, exposed roof timbers, a modest footprint opening onto generous volume: these properties call for renovation down to the last millimetre. The same questions arise for attic apartments, common around Grandes Carrières, as well as for the studios and small apartments that make up a large share of the local housing stock. Insulation, thermal treatment of the skylight, storage built into the sloped ceilings, and respecting usable head height all determine whether the project succeeds.
The Butte Montmartre and sign-off from the Architecte des Bâtiments de France
Part of the Butte Montmartre and the area around the Sacré-Cœur fall within a heritage protection zone. In practical terms, any work that alters the exterior appearance of an apartment, replacing windows, guardrails, or elements of the façade and roofline, requires approval from the Architecte des Bâtiments de France (ABF), France's heritage architecture authority. This approval comes on top of the co-owners' association's sign-off and needs to be planned for from the design phase onward. Anticipating it early removes the single biggest risk of delay on a renovation project in Montmartre.
These constraints apply only to the exterior. Reconfiguring the layout, redoing a kitchen or a bathroom remains unrestricted, subject to the building's co-ownership regulations.
Load-bearing walls and co-ownership: what's actually possible
Opening the kitchen onto the living room, combining two bedrooms into a primary suite: in the period buildings of the 18ᵗʰ arrondissement, projects like these sometimes involve a load-bearing wall. It's entirely achievable, provided a clear process is followed: a structural study carried out by a qualified engineering firm, installation of a properly sized support beam, and prior approval from the co-owners' general assembly, since the building's structure is considered common property. How long that approval takes depends on the general assembly's calendar: a scheduling factor to build into the plan, not an obstacle. A non-structural partition, by contrast, can be moved without any special authorisation, and that's the case for most of the partition walls in these buildings.
The neighbourhoods of the 18ᵗʰ arrondissement where we work
The 18ᵗʰ arrondissement is far from uniform. From one side of the Butte to the other, from Montmartre to the Goutte d'Or, the building stock changes, and with it, the nature of the renovation work required. Maison Kyka works across the entire arrondissement, as we do in every district of Paris.
This neighbourhood-by-neighbourhood breakdown isn't just theoretical. A project on the Butte comes with access and parking constraints unlike anything you'd face on the wide avenues in the lower part of the arrondissement. Likewise, the late-Haussmannian buildings around Caulaincourt call for a different approach than the compact spaces of Montmartre. In the former, the reception rooms get opened up. In the latter, every square metre counts. All of this is planned for in advance, and priced accordingly.
Turnkey, bespoke renovation, from design to move-in
Maison Kyka: one point of contact, all the way to the furnishings
Plenty of firms promise a single point of contact for your renovation. At Maison Kyka, our commitment goes beyond the end of construction: our team designs the project, coordinates the various tradespeople on site, furnishes the apartment, and delivers it ready to live in. You won't be coordinating contractors, hiring a decorator afterwards, or handling a shopping list on your weekends. One contact follows your renovation project, from the very first survey to the handover of the keys.
This bespoke, turnkey service is built for those who have neither the time nor the desire to juggle eight different trades. We take the space as it is, and we hand it back to you finished.

The stages of your project
Whatever the scope of the work, the process follows the same path:
- Acquisition: a property search with a search mandate and administrative support, if you haven't yet found the property.
- Design and planning: survey of the existing space, analysis of the building's constraints, floor plans, choice of materials and finishes.
- Permits and approvals: notification to the co-owners' association, general assembly approval if the structure or common areas are affected, and, where applicable, a filing with the ABF for properties in a protected zone.
- Renovation work: demolition, second-fix works, utilities, code compliance, kitchen, bathroom, finishes.
- Furnishing and decoration: bespoke or curated furniture, textiles, lighting, tableware.
- Handover: the apartment is cleaned, furnished, and set up, ready for you to move in with nothing but your suitcases.
Every stage comes with regular site monitoring, including progress updates and a schedule kept current. Our clients always know where things stand with their apartment, without having to ask.
"The team is incredibly responsive and attentive, the work was finished on schedule (rare in Paris), and the result is truly beautiful." Caroline J.
The technical work behind a full renovation
In a period apartment in the 18ᵗʰ arrondissement, most of the effort goes into work you'll never see once the site is finished.
Plumbing and electrics come first. In buildings from the late 19ᵗʰ century, the utilities have often been patched piecemeal over the decades. A full renovation redefines them entirely: an up-to-code electrical panel, reworked supply and drainage lines, and water points repositioned to match the new layout.
Floors and walls come next. Restoring the original parquet where possible, choosing finishes for wet rooms, bathroom tiling, surface preparation and paintwork. It's this finishing work, invisible on a floor plan, that sets a carefully executed renovation apart from a rushed one. Fixtures and bespoke joinery are installed last, once every surface is perfectly prepared.
Finally, the kitchen and bathroom account for the largest share of the technical budget, since they combine utilities, finishes, joinery and fixtures. They're also the two rooms where bespoke design matters most in the small apartments of the 18ᵗʰ arrondissement.
What budget should you plan for a renovation in the 18ᵗʰ?
No two apartments in the 18ᵗʰ arrondissement are alike, and an accurate quote can only be given after an on-site visit. That said, here are the ranges typically seen on the Paris market for renovating a period apartment, depending on the scope of work.
A simple cosmetic refresh limited to paint and flooring follows a different logic and isn't a renovation in the sense we mean here. Furnishing, decoration and a move-in-ready delivery, on the other hand, come on top of these figures, depending on the level of service chosen.

Five factors make the budget vary from one project to the next.
- Floor area and layout: relocating a wet room costs more than redoing it in place.
- The condition of the utilities: an apartment whose electrics and plumbing haven't been touched in decades needs a full code upgrade.
- The scope of the work: a partial renovation of a bedroom or kitchen is a different undertaking from a full renovation involving new partition walls.
- The level of finish and materials chosen: parquet, tiling, wall coverings, all of which can shift the second-fix budget considerably.
- The building's constraints: no lift, a narrow staircase, difficult access on the Butte, co-ownership rules around working hours on site.
On the tax side, home improvement work on a property completed more than two years ago qualifies for 10 % VAT, and certain energy-renovation work qualifies for 5.5 % VAT. These rates are factored into our quotes.
An accurate quote is therefore only given on site, after visiting the apartment. It's also what protects your project from unpleasant surprises and cost overruns once work is underway.
How long does the work take?
Plan for a few weeks for a simple refresh, roughly 3 to 5 months for a full renovation, and 6 to 9 months for a major renovation involving a full layout reconfiguration. On top of the construction timeline come the approval delays: the co-owners' general assembly calendar if the structure is involved, and the ABF review process in protected zones. At Maison Kyka, these administrative timelines are identified from the design phase onward, so the schedule we give you is the one that actually happens.
Renovating to live in or to rent out
In the 18ᵗʰ arrondissement, a significant share of renovations aren't intended for the owners themselves to live in. The district remains one of the favourite grounds for rental investment in Paris, and that changes how the work is approached.
For a primary residence, the renovation optimises how you live in the space: layout, storage, wet rooms, natural light. For a rental investment, the goal is getting a flawless property onto the market quickly. An apartment delivered furnished and decorated can be rented out from the moment the keys are handed over, without the weeks of setup that typically delay a first letting. Maison Kyka supports both types of projects, from a buy-to-renovate strategy aimed at rental income to a primary residence designed to last.
Energy performance has become the tipping point for these projects. Homes rated G on the French energy performance certificate (DPE) have been banned from rental since 2025, and those rated F will follow in 2028. Many period apartments in the 18ᵗʰ arrondissement, with their single glazing, poorly insulated eaves or original skylights, are affected. A well-designed renovation addresses this within the same project: insulating sloped ceilings and walls from the inside, replacing windows (with ABF approval where required), and improving the thermal performance of skylights without altering their character. The apartment gains the energy rating it needs to stay rentable, along with the comfort it needs to be genuinely liveable.
Our projects in the 18ᵗʰ arrondissement of Paris
Éloi's apartment, a beautiful 54 m² (581 sq ft) property in the Jules Joffrin neighbourhood, underwent a full renovation for a budget of €108,000 (excluding Maison Kyka's fees) over five months of work. His new primary residence showcases Maison Kyka's approach: interior architecture designed down to the millimetre, where every piece of storage and every flow of movement is drawn for the apartment's actual volume rather than a generic floor plan.

Still looking for a property to renovate?
Many of our projects start right from the acquisition stage. In the 18ᵗʰ arrondissement, where properties in need of renovation are in high demand and their true condition is hard to gauge from listing photos alone, assessing the scope of work during the viewing changes the terms of a negotiation.
Maison Kyka also supports you in the search itself, through an exclusive or non-exclusive search mandate. We visit properties with you, we cost the renovation on the spot, and you know exactly what the apartment you're considering will really cost: purchase price and renovation budget combined.
