For professionals · Landlords, management companies and estate agents
Architects for landlords, management companies and estate agents with several homes
What we solve
Your portfolio’s technical documentation, all in one go
Everything notaries, land registries, public authorities and tenants ask for, prepared by registered architects.
Certificates of habitability
Visit, checks and application to sell or let, including for several homes at once.
Energy certificates
Visit, calculation and registration of the energy performance certificate for each home or commercial unit.
Descriptive and building age certificates
They describe the property and certify when it was built, for deeds, the Land Registry or regularisation.
Asbestos certificate
Inspection and certificate for homes and buildings.
Measured survey drawings
The current state of each property drawn up, as a basis for letting, selling or renovating.
Change of use from commercial premises to home
Preliminary feasibility study and, if it goes ahead, project, planning permission and site management.
How we work
Many properties, one point of contact
We organise the work so that handling ten certificates does not cost ten times as much as handling one.
1. You send us the list
Addresses, cadastral references if you have them and any available documentation.
2. Joint quote
A single quote for all the properties, with a breakdown for each one.
3. Grouped visits
We organise them by area and coordinate them with your deadlines and with the tenants.
4. One point of contact
An architect from the team is your contact for every file.
5. Delivery and submission
We send you the certificates and reports and submit whatever is required to the authorities.

Property portfolios: all the technical documentation in a single assignment
Anyone who manages property portfolios knows the problem is not one certificate but fifty: each with its own visit, deadline and paperwork. Grouping them into a single assignment cuts down on travel, simplifies invoicing and lets you track every file through one contact.
Before the visits start, we review the documentation that already exists —previous certificates of habitability, energy certificates or drawings— and tell you what is missing to sell, let or regularise each property.
And when a home needs more than paperwork, as in the renovation of the flat on Carrer Cartagena, the same team draws up the project and manages the works.
Projects
Homes ready to sell or let
As well as certificates for property portfolios, we design and manage the renovations that get each property ready for the market.
Flat renovation in Sant Antoni
83 m² in a 1960s building on Carrer Comte Borrell: kitchen opened up to the living room, one hallway fewer and two more comfortable bathrooms. See project →
Penthouse on Muntaner, Eixample
Renovation of a 90 m² penthouse with an open plan, changes of level and the original brick wall restored as the centrepiece. See project →
From commercial premises to home next to Sant Pau
The preliminary study revealed that the ground floor was already registered as a home, which avoided the change of use and sped up the certificate of habitability. See project →
Where we work
Barcelona, plus area campaigns across Catalonia
For property portfolios in Barcelona and its metropolitan area, we work every day.
Elsewhere in Catalonia we organise visit campaigns by area: when there are several properties in the same town or district, we visit them on the same day.
