Confirmed buyer interest — direct engagement process
We ran a direct buyer engagement process to understand requirements, fine-tune the presentation and confirm what buyers valued most. This allowed us to consolidate the property's positioning and reach a sound outcome for all parties.
Value Methodology · José Francisco
T3 → T3+1 + Suite
Reconfiguration without area increase — more value, same m²
21 m² social area
Open kitchen + living room — the most requested value-add in today's market
6 months · Full scope
Works completed on time and within the contracted scope — no surprises
Appreciation above cost
Value uplift exceeded total investment in works and coordination
How we measure success: we compare the market value of the property at acquisition with the post-renovation asking price — net of total intervention cost (works, coordination and permits). The positive differential is the value uplift generated. In this project, the differential was favourable and the sale completed directly by the owner, without a selling agent.
Initial Condition · Dec 2022
Before Kitchen — yellow cabinets, granite and 1970s patterned tiles
Before Bathroom — bathtub, decorative tiles and original 1970s floor
Before Entrance hall — dark corridor, carpet and old window frames
Before Detail — damp tiles, aged overall appearance

Floor Plan Transformation
Original T3 — 3 separate bedrooms, closed kitchen, 2 bathrooms
New layout T3+1 + Suite + Service Bathroom — open-plan kitchen
The reconfiguration created a complete suite, a service bathroom and an additional room (+1), without increasing total floor area — unlocking potential the property already had. Opening the kitchen to the living room merged two separate spaces into a single 21 m² volume.

Works and contractor management
Direct sale by owner — no selling agent
Rereading the existing layout — a T3 with 40 years of construction — allowed us to develop a new functional programme that makes full use of every square metre. Opening the kitchen to the living area, creating the suite and adding the service bathroom responds to today's demand for domestic flexibility, privacy and everyday comfort.
The sales process included a direct buyer engagement moment, allowing us to gauge value perceptions, adjust communication and consolidate the property's positioning. Visitors highlighted the coherence of the overall project — the relationship between natural light, materials and colour palette — and the versatility of the spaces. The outcome was a sound and balanced process for all parties.

Floor Plan Transformation
Original T2 — compartmentalised, closed kitchen, no +1
New layout T2+1 — open concept, home office, solid Jatobá wood floor
Removing the wall between kitchen and living room created a social volume of over 40 m². The private storage was converted into a fully equipped home office. The property also retains expansion potential to T2+2.

Identified potential: T2+2
Layout analysis revealed room to create a second additional room without major structural works — an option to consider in a future renovation or phased sale.

This property belongs to the SISO principal. We include it because it demonstrates exactly how we apply our own method when we have full skin in the game — the same rigour, the same data, the same process we use for our clients.
Active 2025 upgrades: collective infrastructure for individual EV charging and professional workstation setup in the 15 m² private storage unit.

Complete technical dossier — 7 phases · 55+ drawings
Project P2026/08 focused on the rigorous planning of a full renovation of a T3 acquired with energy rating F. Before any works began, SISO produced a set of 7 technical plans documenting every phase of the process — from the current-state survey to the optimised final layout — ensuring clarity of execution for all parties: owners, contractors and specialist teams.
The phased methodology eliminates ambiguity on site, reduces budget overruns and enables informed decisions at each stage. The result is a complete technical dossier — with more than 55 technical drawings — serving as the basis for contracting, coordination and works supervision.
