Technical consulting

In order to give solutions for our clients we develop many proposal.

Our process follows a path that goes from compliance with current regulations, through the coexistence of business activity with the works, to the forecast of future changes in these spaces. QUADRATURE establishes a collaborative process with the client about important key in business: the deadline and the execution budget.

  • Adaptation to regulations
  • Economic feasibility study
  • Documentary management (licenses and responsible declarations)
  • Sustainability (LEED, BREEAM) and health and wellness (WELL) certifications.
  • Facility engineering
  • Management of licenses and legalizations

Space design

We create designs based on the strategy of the activity to be developed and the people who interact in those spaces, whether it is a hotel lobby or an office reception area. We work the workplace with the client. We plan workspaces (in which we prioritize healthy and safe environments) to obtain the highest user satisfaction and greater efficiency in the business, without forgetting the new trends in decoration, lighting or materials and colors. And we got it.

  • Definition of the workspace strategy (workplace)
  • Look & Feel
  • Interior architecture
  • Definition of materials
  • Branding

Contract and FF&E

The experience of QUADRATURE’s team is developed in numerous types of spaces in buildings of various types, although it is true that we are especially significant in the hotel, office and restaurant/commercial sectors. Therefore, we understand the needs such as durability, cleanliness and comfort of the furniture that these types of establishments require, without abandoning fashion or trends. We provide specialized equipment solutions with a balanced balance between quality and cost.  And we adjust that balance.

  • Design & Creation
  • Specification of furniture and equipment
  • Advice on the choice

Fit Out y Reforms

In QUADRATURE we have procedures to undertake the integral process that leads to an interior space to be able to be used and legalized. In the diversity of circumstances that occur in the reform works, both integral and partial, are decisive -beyond an optimal design- issues such as safety in the execution, the regulations applicable to each professional activity or the reduction of energy consumption. This global conception of the project is one of our axes.  We have an extensive background in sustainability certifications (WELL™, LEED® or BREEAM®).

Moreover, we have a whole battery of customized solutions to adapt, in interior spaces, a strategy against Covid-19.  And we know what we are talking about.

Our extensive experience in construction allows us to offer a comprehensive portfolio of services, turnkey and with full control of the process:

  • Comprehensive management of construction execution (architecture and engineering).
  • Construction management with other systems: open books, by certifications, etc.
  • Supply and assembly of furniture and equipment.
  • Start-up and legalizations
  • Maintenance and refurbishment

Our philosophy is based on three pillars: technical quality, service excellence and trust based on flexibility. We are experts in meeting deadlines and costs, and in reducing the risks inherent in these processes.


As a key part of the habitability and functioning of interior spaces, installations -as a whole- are a determining factor in our professional activity and on which we focus our expertise. We list some of our specialization in these areas:

Air conditioning and ventilation, including special actions to install high efficiency filters against COVID. We install production systems with energy-efficient boilers and all kinds of solutions.

  • Low and medium voltage electrical installations.
  • Fire protection (detection, extinction).
  • Telecommunications, networks and DPC.
  • Plumbing, sanitary hot water and sanitation.
