Projects for home renovation and alteration

Our projects show how careful design and sound building drawings can turn existing homes into comfortable, sustainable and future-proof houses.

Throughout the Netherlands, with a strong focus on urban areas and existing residential neighbourhoods, we guide renovations, alterations and extensions for private clients and smaller developers.

  • From 1930s houses and post-war terraced homes to apartments and detached houses
  • Architectural quality combined with technical feasibility
  • Tailored to the home, its use, the regulations and the budget
Every building needs its own answer

Renewing existing homes as a whole

From a compact intervention to a complete transformation: layout, structure, comfort, energy and appearance all affect each other.

Tailored work in existing buildings

Combining architectural quality and smart technology

The type of home, building period, surroundings and future plans determine which interventions are suitable. That is why we assess spatial wishes together with structure, building services, regulations, phasing and a realistic budget.

The result is not a standard solution, but a project approach that suits the character and everyday use of the building.

Home and living space

Renovation, extension and roof extension

The first project categories focus on improving existing homes and adding usable living space.

01 / Complete renewal

Complete home renovations

In a complete renovation the home is approached as a whole: layout, structure, insulation, building services and finishes are studied as one design question.

Features of this project category:

  • Thorough improvement of floor plans and circulation
  • Extra daylight, sightlines and connection with the garden, balcony or street
  • Renewal of kitchen, bathroom and plant rooms
  • Better insulation, ventilation and energy use
  • Matching new parts to the existing structure and detailing

Clear phasing can help you keep living in the home where possible or keep the construction period manageable.

02 / Adding space

Extensions and roof extensions

Many projects aim to add usable square metres with an extension, bay window, roof extension or carefully fitted dormer.

In this project category:

  • We design volumes that suit the existing house and the streetscape
  • We look for a logical connection between old and new parts
  • Structure, site logistics and adjoining buildings are studied early
  • The new volume becomes part of the overall energy and comfort concept
  • Daylight, the connection with the garden and everyday circulation get extra attention

This creates more living space without losing sight of the character of the home.

Performance and reuse

Sustainable renovation and transformation

Making existing buildings future-proof calls for a balance between preservation, comfort, energy, technology and new uses.

03 / Comfort and energy

Energy-efficient and sustainable renovations

An important part of renovation focuses on lower energy use, better comfort and a smaller CO₂ footprint.

Projects in this category can include:

  • Better insulation of the roof, facade, floor and glazing
  • Efficient building services, heat pumps and low-temperature heating
  • Solutions for sun shading, natural ventilation and overheating
  • Integration of solar panels and smart meters where technically sensible
  • Step-by-step measures linked to maintenance and alterations

The measures are matched to the type of home, the available information, the budget and the residents' future plans.

04 / New uses

Transformation of existing buildings

In a transformation, a building gets a different layout, a new function or a fundamentally different use. That calls for insight into existing quality and future performance.

In this project category:

  • Valuable existing elements and architecture are studied
  • New types of homes and living concepts can be introduced
  • We look for a balance between heritage, sustainability and comfort
  • Access, daylight, fire safety and building services are considered together
  • Where relevant, we coordinate with the municipality, housing association and other partners

The aim is a building that becomes usable again and meets today's living wishes and technical requirements.

Innovation and knowledge development

Serial renovation and European references

Not every method suits every building. Repeatable types of homes can, however, offer opportunities for prefabrication, standardisation and a better prepared building process.

05 / Repeatable approach

Serial and industrial renovation

We follow innovative European developments in serial renovation with prefabricated elements and industrial processes. For suitable projects we investigate which principles can be applied.

A serial approach can aim at:

  • Shorter work on site through better preparation
  • Options for residents to keep using parts of the home
  • Prefabrication of facade, roof and services modules
  • Repetition and standardisation in terraced and multi-storey housing
  • Fewer failure costs through fixed details and controlled processes

Feasibility depends on scale, type of home, dimensions, ownership, logistics and available market parties.

06 / Learning from reference projects

Projects in the Netherlands and Europe

Our approach is in line with a broader European movement towards high-quality, sustainable home renovation. Projects in the Netherlands and other countries offer valuable lessons, without being presented as our own completed projects.

Key lessons from these references:

  • Technical innovation works better when residents are involved early
  • Good preparation and clear drawings can shorten construction time
  • Renovation is also about liveability, identity and social cohesion
  • Maintenance, energy and living quality should be seen as one programme
  • Cooperation between designers, builders, residents and clients is essential

We use these insights to develop our own design and preparation processes further.

Careful project presentation

Presenting projects carefully and verifiably

A good project presentation makes the challenge, design choices and results clear. That is why we publish photos, drawings, locations and project results when reliable source information and the necessary permission are available.

  • Describing the project challenge and existing situation factually
  • Making design choices and the technical solution clear
  • Clearly stating the project phase and Amstelada's role
  • Using approved images only
  • No numbers, savings or performance claims without evidence
Projects FAQ

Frequently asked questions about renovation projects

Which kinds of renovation projects does Amstelada guide?

The project types include complete home renovations, extensions, roof extensions, sustainable renovations and transformations of existing buildings. The exact scope is set per assignment.

Can a renovation be carried out in phases?

Yes. Depending on the home, site logistics, occupancy and available resources, a renovation can be prepared in phases. The consequences for design, technical work and schedule must then be assessed together.

Are energy measures integrated into the design?

Yes. Insulation, glazing, ventilation, heating, cooling and, where useful, solar panels can be matched to the type of home, the budget and future plans.

What does serial or industrial renovation mean?

In serial renovation, repeatable components and processes, such as prefabricated facade, roof or services modules, are prepared so that work on similar homes can be organised better.

How are project cases selected for publication?

Amstelada publishes project images, locations and results when verified information and the necessary permission are available. Until then, this page describes the project categories and approach.
