The services presented cover property purchases, sales, letting, management and renovation.

Trinity is also presented, comprising three condominium apartments. An in-house marketing service develops marketing strategies and campaigns for sales and lettings.

Editorial context
Working with a provider in Lausanne – what matters
Anyone appointing a property developer in Lausanne should first distinguish between property development, new-build marketing and subsequent property management. These activities can be connected, but they are not interchangeable. For de Rham, the supplied sources primarily document the marketing of new residential projects. Prospective clients should therefore establish which development tasks the company would undertake and which would remain with other parties.
For a specific project, a written scope should define responsibilities, deadlines, fees and reporting arrangements. Discussions should cover coordination with design and construction teams, as well as the interfaces between marketing, letting and management. The projects listed in Ecublens and Crissier provide a basis for asking about experience with comparable sizes, uses and target groups. Their inclusion does not establish responsibility for their entire development.
For the documented marketing services, relevant topics include target audiences, marketing channels, campaign budgets and performance monitoring. If letting is also required, application procedures, viewings, handovers and information flows should be agreed. For the digital portals, clients should clarify access rights, document availability and responsibility for responding to enquiries.
The supplied review selection mainly concerns communication during a tenancy or the process leading up to it. It does not replace checking development references, but supports discussing availability and response procedures explicitly. The scope of the advertised legal support should also be clarified before appointment.

In the provided selection of three one-star reviews, communication is a recurring concern: reviewers describe delayed or missing replies, repeated follow-ups and interactions they perceived as unaccommodating.

Ganz schlecht. Komplizierte besichtigung. Falsche Angaben und Versprechungen. Und letztendlich eine Absage mit einem Link zu einer Wohnung bei der man sich bewerben soll. Für dass man nochmals hingehalten wird? Danke, nicht wieder!
Je n’ai même pas encore commencé mon contrat de bail et mon expérience avec cette régie est déjà extrêmement négative. Depuis plus d’un mois, j’ai dû multiplier les appels téléphoniques et les e-mails pour obtenir des informations essentielles concernant mon entrée dans le logement. Sans mes nombreuses relances, j’ai sincèrement l’impression que je n’aurais reçu aucune information. La communication est très difficile, les réponses tardives voire inexistantes, et le respect du locataire ne semble malheureusement pas être une priorité. Malheureusement, je n’avais pas consulté les avis et la note attribuée à cette régie avant de m’engager. Aujourd’hui, après avoir vécu cette situation personnellement, je comprends parfaitement les nombreux commentaires négatifs publiés ici. Après avoir eu affaire à plusieurs régies en Suisse, c’est la première fois que je suis confrontée à un tel manque de
Rarement eu affaire à une gérance aussi peu arrangeante et aussi peu agréable dans ses échanges. Une rigidité absolument déconcertante, une communication pénible et l'impression constante que la moindre demande constitue déjà une contrainte insurmontable. Une expérience qui aura surtout eu le mérite de nous rappeler une chose : bien choisir sa gérance est presque aussi important que bien choisir son logement. À fuir.
