We integrate your expertise into our property projects.

At J&J, we support a property far beyond its sale. Management, letting, renovation, investment or value enhancement: we are building a network of technical partners who share our high standards and become a natural extension of our team.

Our model

Our clients entrust us with their projects. We choose the companies that will deliver them.

At J&J, our clients entrust us with managing their property projects.

We analyse their needs, define the work required, select the companies, coordinate the works and ensure they are completed properly.

Choosing our technical partners is therefore an integral part of our role.

That is why we favour a select network of companies we know well and with whom we share the same standards of quality, communication and reliability.

Working with us

Why join our partner network?

You are not simply joining a list of service providers. You become a delivery partner to a property firm that manages projects from start to finish.

End-to-end projects

We are involved throughout a property's entire life cycle: sale, letting, management, renovation, investment and value enhancement. Your skills naturally have a place across a wide range of projects.

A clear vision

Every assignment forms part of a project we have already analysed. You know the objectives, constraints, schedule and point of contact.

A lasting relationship

We prefer to build long-term partnerships rather than search for a new company for every assignment. Once trust has been established, everyone benefits.

An efficient way of working

We centralise communication with the client, coordinate the various parties involved and oversee the project. This allows everyone to focus on their own area of expertise.

Recognised expertise

Your expertise extends beyond the work on site. We regularly call on our partners to challenge technical solutions, estimate budgets or develop realistic projects.

Examples of collaboration

Our partners are involved at every stage of the projects we manage.

Acquisition

Technical visits, initial estimates, feasibility analysis and works budgets.

Preparation

Repairs, compliance work, refurbishment or targeted work before a sale or letting.

Transformation

Renovation, energy efficiency improvements, restructuring, subdivision or coordination of contractors.

Property operations

Maintenance, upkeep, repairs and technical work on the properties we manage.

Value enhancement

Work designed to enhance a property's value before its sale, refinancing or a new investment.

Support

Because we support our clients over the long term, the same partners may work on several properties and at different stages of their property portfolio journey.

Our clients entrust us with their projects. We entrust their delivery to companies in which we have complete confidence.

How we work

Building a lasting relationship, project after project.

Phase 1

Getting to know your company

We take the time to understand your business, your specialist areas, how you work and the projects to which you bring the greatest value.

Phase 2

Working together

We naturally begin with a few assignments so that we can jointly assess the quality of delivery, communication and ease of collaboration.

Phase 3

Becoming a trusted partner

When the collaboration works well, we naturally call on your company for our future projects. You become an established partner of our team.

Phase 4

Growing together

Over time, your expertise is incorporated at a very early stage of our planning. We call on you to help shape projects, challenge proposed solutions or refine budgets, well before work begins.

What if we built this relationship together?

We are looking for companies that share our commitment to quality, our dedication to service and our desire to build lasting partnerships.

Our standards

The companies we choose reflect J&J's standards

When we manage a project, our clients trust us to make the right decisions, including when selecting contractors. We therefore choose partners capable of delivering the same high standards and professionalism expected of J&J.

Impeccable workmanship

Meticulous execution, commitments honoured and consistent quality.

Seamless communication

Because a project progresses more smoothly when everyone shares the right information at the right time.

A sense of responsibility

Meeting deadlines, transparency, responsiveness and the ability to find solutions.

Trust built over time

We are not looking for the cheapest or most prominent partner. We are looking for companies we want to work with for years to come.
