Comprehensive Penthouse Renovations in Barcelona and Metropolitan Area
Reformayahorra has been delivering comprehensive penthouse renovations in Barcelona and the Metropolitan Area since 1995. We renovate penthouses with terraces, duplex penthouses, attic roof spaces, and older penthouses ready for living, selling, or renting, including layout redistributions, terrace and rooftop optimization, waterproofing, thermal insulation, natural light optimization, kitchens, bathrooms, electrical systems, plumbing, climate control, flooring, carpentry, painting, lighting, permits, trade coordination, and full site supervision.
A comprehensive penthouse renovation updates the entire property, improves layout efficiency, maximizes the terrace or rooftop, solves thermal insulation challenges, increases natural light, updates outdated utilities, modernizes kitchens and bathrooms, and prepares the penthouse for daily living, sale, or lease. Prior to issuing a quote, we inspect the penthouse's current condition, the roof structure, terrace, owner requirements, scope of work, and necessary itemized tasks.
This page focuses on complete penthouse renovations. For other property types, feel free to explore our comprehensive renovations, apartment renovations, and house renovations.
Scope of service

Not every penthouse requires the exact same scope of work. An older penthouse may need full utility overhauls, insulation enhancements, or terrace waterproofing checks, whereas a newer penthouse might primarily focus on layout adjustments, kitchen, bathrooms, flooring, and cosmetics. Therefore, the scope is clearly defined following an initial technical visit.
Penthouse types
Types of penthouses we renovate
Reformayahorra renovates various types of penthouses across Barcelona and its Metropolitan Area. Each project is tailored according to initial conditions, building age, floor plan, utilities, natural light, ventilation, terrace or roof condition, intended use, and allocated budget.
Penthouses with terrace or rooftop
Penthouses with private terraces derive the greatest benefit from a comprehensive renovation. Waterproofing, drainage, outdoor paving, access points, lighting, solar protection, and indoor-outdoor continuity should be thoroughly reviewed to make the space usable year-round.
Duplex penthouses
Duplex penthouses demand careful integration between both levels: staircases, day vs. night zone layout, floor-by-floor bathrooms, technical installations, lighting, and vertical clearance utilization. Planning is critical to guarantee both stories function seamlessly.
Attic roof penthouses
Attic penthouses with pitched ceilings or loft spaces require maximizing headroom, upgrading thermal insulation, adding daylight through roof windows or skylights, and optimizing ventilation for maximum comfort and usable square footage.
Older or inherited penthouses
An older or inherited penthouse usually demands a full modern overhaul before being occupied, sold, or rented. We evaluate the state of the kitchen, bathrooms, plumbing/electrical networks, layout, flooring, joinery, terrace, and roofing to craft a renovation plan matched to the owner's goals.

Budget
How much does it cost to renovate a penthouse
The cost of renovating a penthouse in Barcelona is determined by square meters, initial condition, terrace/rooftop features, waterproofing, thermal insulation, layout changes, kitchen, bathrooms, utility upgrades, daylighting solutions, materials, permits, and finishes. A technical site inspection allows us to translate these variables into an itemized, transparent budget.
| Factor | How it affects the budget |
|---|---|
| Square footage | Larger areas require more materials, labor hours, skilled trades, and logistical coordination. |
| Initial condition | An older penthouse may need full utility rewiring/replumbing, structural remediation, insulation, or reinforced scope items. |
| Terrace and rooftop | Waterproofing membranes, drainage systems, exterior paving, access doors, awnings, or enclosures can expand scope. |
| Insulation and roofing | Enhancing roof insulation or repairing roofing elements impacts long-term comfort, energy efficiency, and cost. |
| Floor layout | Moving walls, creating open-concept spaces, adapting sloped ceilings, or connecting duplex levels adds technical complexity. |
| Natural light | Installing skylights, light tubes, or roof windows may require specialized roofing work. |
| Kitchen | Cabinetry ranges, countertop selections, appliances, electrical/plumbing adjustments, and ventilation significantly affect costs. |
| Bathrooms | Plumbing updates, walk-in showers, sanitaryware, glass enclosures, tiling, ventilation, and fixtures impact pricing. |
| Utility installations | Electrical panels, piping, heating/air conditioning, mechanical ventilation, and data lines form major budget items. |
| Materials and finishes | Flooring, interior doors, paint types, wall tiles, and light fixtures vary based on selected quality tiers. |
| Permits | Interventions on terraces, roofs, or shared building elements may require prior municipal notifications, technical plans, or licenses. |
To prevent budget surprises, Reformayahorra inspects the penthouse's current condition, terrace, roofing, layout, systems, kitchen, bathrooms, insulation, materials, and local regulations before solidifying line items and timelines.

Terrace, rooftop, and waterproofing
The private terrace or rooftop is one of a penthouse's primary assets and, simultaneously, one of the most vital areas to assess. Before upgrading its look, waterproofing integrity, drainage slopes, exterior paving, access points, utilities, solar shading, and indoor integration must be thoroughly tested. Poorly waterproofed terraces can cause severe water damage to lower levels, making waterproofing a top priority in penthouse projects.
Roof or terrace usage must always be evaluated according to space ownership, municipal zoning codes, homeowners' association guidelines, and actual scope of work.
- Waterproofing membrane.
- Drainage and slope correction.
- Outdoor paving.
- Doorways and threshold levels.
- Exterior window & door joinery.
- Exterior lighting.
- Sun protection & awnings.
- Enclosures compliant with local codes.
- Outdoor water & electrical supply.
- Planters & greenery integration.
Works performed on terraces, rooftops, or roof structures can impact shared building elements, requiring specific municipal permits or approval from the homeowners' association depending on the municipality, building type, and work scope. Reviewing the specific case before beginning is strongly recommended.
Comfort
Insulation, temperature control, and natural light
Located directly beneath the roof, penthouses naturally experience hotter summers and colder winters compared to lower floors. For this reason, a full penthouse renovation should evaluate thermal insulation, ventilation, exterior joinery, and skylight placement. Addressing these factors improves everyday living comfort, reduces energy bills, and maximizes usable space under sloped ceilings.
Thermal insulation: upgrading under-roof insulation and exterior envelope seals stabilizes indoor temperature year-round.
Natural light: skylights, roof windows, and light wells channel daylight into inner spaces and rooms with limited exterior facade access.
Ventilation: effective airflow prevents heat trapping and moisture accumulation, particularly in enclosed top-floor layouts.
Energy efficiency: adequate insulation, high-performance windows, and modern HVAC systems lower utility costs while enhancing comfort.
If energy savings are a primary goal, explore our specialized energy efficiency services.
Permits & Regulations
Permits for renovating a penthouse
Permits required for penthouse renovations depend on your municipality, building classification, and project scope. Cosmetic updates usually require simple notifications, whereas terrace, rooftop, roof structure, facade, or structural modifications may demand technical documentation and approval from the building's homeowners' association.
- Interior cosmetic updates.
- Kitchen remodeling.
- Bathroom remodeling.
- Floor plan redistribution.
- Utility system alterations.
- Terrace and rooftop renovations.
- Roof structural or waterproofing work.
- Skylight or roof window installations.
- Structural or accessibility modifications.
- Construction waste disposal permits.
- Public sidewalk occupancy for skip or container placement.
- Coordination with homeowners' associations when applicable.
Permit information provided is indicative. Requirements vary according to municipal town planning codes, penthouse type, building state, affected common elements, and project scale. Always review your specific project requirements prior to starting work.
Layout
Penthouse floor plans: making the most of your space
A successful penthouse layout balances room circulation, natural light, cross-ventilation, storage capacity, sloped ceiling heights, multi-level stair flow in duplexes, terrace access, and practical daily use. Before moving walls, we assess room dimensions, ceiling clearances, load-bearing structures, waste pipes, orientation, stairways, and lifestyle needs.
| Layout decision | When recommended | What to review |
|---|---|---|
| Open kitchen to living room | When seeking spaciousness, daylight, and connected living zones. | Load-bearing walls, piping, range hood extraction, ventilation, flooring transitions, lighting. |
| Connect interior to terrace | When the penthouse features an underutilized terrace or rooftop. | Exterior sliding doors, threshold levels, waterproofing, drainage, outdoor lighting, privacy screens. |
| Utilize sloped attic space | When under-roof clearance offers usable vertical volume. | Clear height, thermal insulation, built-in custom storage, skylights, air flow. |
| Reorganize duplex layout | When a two-story penthouse has inefficient traffic flow. | Stair placement, floor-by-floor bathrooms, bedroom zoning, utilities, passage space. |
| Maximize storage space | When the property lacks adequate storage solutions. | Low-ceiling attic areas, entry hall, hallways, bedrooms, custom cabinetry, usable depth. |
| Increase natural daylight | When living areas feel dark or have limited exterior walls. | Skylights, roof windows, glass doors, orientation, continuous reflective flooring. |
Kitchen & Bathrooms
Kitchens and bathrooms in a penthouse renovation
In most penthouse projects, kitchens and bathrooms account for a substantial portion of the budget, timeline, and ultimate design impact. During a comprehensive renovation, technical systems, ventilation, layout, tile coverings, lighting, custom furniture, terrace access, and overall room flow are meticulously integrated.
Kitchens within penthouse renovations
A penthouse kitchen may involve new floor plans, cabinetry, worktops, electrical upgrades, plumbing, extraction ducts, lighting, tiling, and direct terrace integration. As part of a complete project, it is coordinated with overall flooring and design themes.
Bathrooms within penthouse renovations
Bathroom upgrades frequently include tub-to-shower conversions, plumbing renewals, modern sanitaryware, frameless glass screens, tiling, ventilation, lighting, and vanity furniture. Under sloped roofs, headroom clearance and roof windows are key considerations.
Utility Systems
Utilities in a comprehensive penthouse renovation
Updated technical utilities form the backbone of any penthouse renovation, particularly in older properties. Electrical boards, plumbing mains, air conditioning, ventilation ducting, lighting circuits, network wiring, power outlets, and outdoor terrace supplies must be fully checked and renewed before sealing walls, ceilings, and floors.
Electrical wiring: updating distribution boards, power outlets, light points, switches, exterior lighting, and heavy appliance circuits ensures electrical safety and compliance.
Plumbing: renewing supply lines, drainage pipes, water pressure systems, kitchen/bathroom outlets, and outdoor garden taps prevents future leaks or dampness.
HVAC and ventilation: in top-floor penthouses, efficient air conditioning, heating, and mechanical ventilation are essential for year-round temperature control.
Telecoms & data: planning network points, TV sockets, fiber optics, work-from-home stations, and terrace Wi-Fi coverage modernizes the entire living space.
Materials
Materials and finishes for penthouse renovations
Material selections directly determine longevity, maintenance demands, aesthetics, and final expenditure. Prior to choosing materials, we evaluate house utilization, mechanical resistance, solar and rain exposure on terraces, cleaning requirements, humidity levels, design continuity across rooms, and indoor-outdoor integration.
- Interior flooring.
- Exterior terrace deck/paving.
- Wall coverings.
- Paint finishes.
- Interior doors & carpentry.
- Exterior window frames.
- Entry doors.
- Interior lighting fixtures.
- Outdoor weather-proof lighting.
- Roof windows & skylights.
- Custom fitted cabinetry.
- Kitchen countertops.
- Sanitaryware.
- Faucets & hardware.
- Shower enclosures.
In a complete penthouse project, materials are curated cohesively so that kitchens, bathrooms, living spaces, corridors, and terraces share functional durability and consistent aesthetic harmony suited to top-floor exposure.
