ONE PROJECT · ONE RESPONSIBILITY
From the existing structure to a clean handover.
Each layer of a building affects the next. That is why design, construction and technical interfaces are coordinated together.Analysis & planning
The existing building, objectives, feasibility, permits, schedule and budget framework are brought together before work begins.
Strip-out & structural work
Selective strip-out, disposal, openings, masonry, concrete and necessary structural reinforcement.
Envelope & building physics
Roof, façade, windows, thermal insulation, moisture control and acoustic protection as a coordinated building assembly.
Interior fit-out
Walls and ceilings, drywall, plastering and painting, floors, doors, stairs and fitted elements are coordinated with the technical connections.
Building services
Interfaces between plumbing, heating, electrical work, lighting, ventilation and smart home systems are defined early.
Construction management & handover
Schedule, cost and quality control, acceptance inspections, defect management and documented handover.
HOW AN IDEA BECOMES A CONSTRUCTION PROJECT

Inspect & hand over
Work, outstanding items, operation and relevant documents are reviewed and finalised together.
HOUSE REFURBISHMENT · ADDITION · EXTENSION
Create more space or comprehensively renovate a house?
For an extension, we first assess the plot, existing building, structure, access and utilities, and possible permit procedures. For a house renovation, we establish which building elements can remain and how new rooms, building services and construction phases fit together. You can find a dedicated process for bathrooms, kitchens, floors and building services under Refurbish an entire apartment. Include any existing plans and photos; outstanding points will be clarified during the personal assessment.

All private-client solutionsQUESTIONS & ANSWERS
What clients should know before new builds and remodelling.
What does a complete house or apartment refurbishment cost?+
Costs depend on area, existing conditions, the extent of the work, structure, building services and finish specification. Our online range is a non-binding guide including VAT; a reliable quotation can only be prepared after a survey, planning and consultations with contractors.
When does a refurbishment require a building permit?+
This depends on the project, location and cantonal or municipal requirements. Changes to the structure, use, façade, volume or access and services must be clarified early with the responsible authorities and designers.
Can renovation take place in stages or while the house is occupied?+
Often, yes. Protection, temporary arrangements, access, noisy and dusty phases, and service shutdowns must be realistically incorporated into the construction schedule.
Who coordinates the different trades?+
Central project management brings together planning, schedules, costs, contractors, interfaces, inspections and handover. Responsibilities and approvals are clearly defined before work begins.
How are cost changes during construction handled?+
Changes are described, assessed and approved before execution. A clear decision and variation process protects the budget and schedule better than blanket promises.
Which documents help with the initial assessment?+
Floor layouts, photos, existing plans, year of construction, known alterations, your preferred date and a realistic budget range are helpful. Up to eight photos can be sent directly during your personal consultation.
How can we obtain a suitable quotation?+
Describe your project in the contact form. We discuss your wishes and the existing building in person, then prepare a written quotation once the scope has been assessed.
