Space for housing wishes

The Housing cluster consists of four house building and development companies, ERA Contour, Groothuis Wonen, Hazenberg Bouw and Koopmans Bouwgroep, – each with its own specialisations – the supply company Voorbij Prefab and the building systems companies Comfort Partners and WTH. Together, they form a strong chain. By working closely with each other, the TBI companies are in an even better positon to satisfy the changing wishes of their clients. Consumers have become more individualistic and harder to slot into categories. They want affordable, sustainable, low-energy and comfortable homes that are also distinctive.

Building systems are playing a more pronounced role in construction and maintenance. Comfort Partners, a specialist in this area, is therefore often involved in designing housing. By offering service and maintenance contracts, it can give consumers and commercial clients peace of mind even after completion. We have also noted that home maintenance and renovation are increasingly being linked to the sustainability and quality of the built environment. Comfort Partners works with WTH on smart solutions in both areas.

The recovery in the housing market made it a good year for the TBI companies in the Housing cluster. Newbuild output in the Netherlands rose by 12% in 2016 and repair and renovation output by 25%. Approximately 54,000 new housing units were completed (source: EIB).

TBI sold 2,282 housing units in 2016 (2015: 1,707 units), an increase of 34%. Of the total, 1,169 were sold to private buyers (2015: 1,507), 806 to investors (2015: 108) and 307 to housing associations (2015: 92). The stock of completed but unsold housing as at 31 December 2016 was 2 (31 December 2015: 4). The number of unsold units still under construction as at 31 December 2016 was 117 (31 December 2015: 102). WTH fitted underfloor heating in 10,230 houses and apartments in 2016, in contrast with approximately 7,400 in 2015. WTH is now the market leader in the Netherlands.


ERA Contour, Groothuis Wonen, Hazenberg Bouw and Koopmans Bouwgroep have carried out many studies in the TBI WOONlab of the changes in housing wishes in recent years. In the innovation lab they work with clients and consumers to create new processes and products for newbuilds and energy efficient homes. The newbuild concepts of lekkerEIGENhuis and beterBASIShuis have been developed in TBI WOONlab in recent years. Thanks to the cooperation with Voorbij Prefab, these ‘industrial housing units’ can be made in a variety of styles, making each home unique. The building systems fitted by Comfort Partners and WTH create comfortable, sustainable and safe homes. In 2016, we sold 280 lekkerEIGENhuis units and 265 beterBASIShuis units. TBI WOONlab worked on many projects in 2016, including CenterCity, an apartment concept that is compatible with the sharing economy.

A future-proof solution to an urgent demand

TBI believes everyone has a right to good housing. This includes refugees who are allowed to stay in the Netherlands but do not have a roof over their heads. Inspired by this belief, TBI WOONlab has taken the initiative to develop housing for refugees who have been granted asylum status. This has resulted in the basisTHUIS concept. Several flexible units can be designed within these dwellings and if market demand changes, they can be converted into single family homes relatively simply.

Standardised and varied output

Our concrete factory, Voorbij Prefab, has produced more than 700 prefabricated housing units since it was fully robotised and automated in 2015. Automated production lines produce exterior and interior walls directly from a Building Information Model (BIM), including the building systems fittings and door and window frames. Voorbij Prefab is also working on new products and services so that it can serve the building companies even better and they can in turn strengthen the housing concepts. They include prefabricated exterior skins of cavity walls and interior walls.

Strengthening the cities of the future

Together with their clients and the residents, the TBI housing companies are also adept at redeveloping older urban districts and industrial areas into pleasant neighbourhoods that people enjoy living in. Sustainability is an important factor. Hazenberg Bouw, Mobilis, Voorbij Funderingstechniek and Blauwhoed, for example, revitalised the Santrijn area in the centre of Oosterhout. ERA Contour and Heijmans are carrying out a multiyear project to develop Nieuw Crooswijk a modern, green urban district in the north of Rotterdam for a mixed target group. In 2016 the two parties signed an agreement with the municipality of Rotterdam to develop Nieuw Kralingen.

Koopmans Bouwgroep will work with Amvest in Amsterdam to redevelop the former Cruquius hindustrial area into a lively multifunctional urban district. The characteristic, historical buildings in the heart of the area will be retained. In the same city, ERA Contour has started construction of Kopblok Houthaven: four buildings accommodating different housing types developed by Synchroon.

The TBI construction companies are converting prominent office and commercial buildings in several large cities into apartments. Examples include the former Institute of Technology in Utrecht, the former Aramco office block in The Hague and Spoorpunt, an eye-catching building in Rotterdam that has been vacant since the 1990s. Spoorpunt is being developed in accordance with ERA Contour’s successful Eén Blok Stad housing concept. The building’s structural skeleton is being completely renovated to a plan devised with the prospective buyers. Behind the front door, the buyers themselves design and build their homes to their own taste using their own budget. The concept has already been successfully applied in Rotterdam and Amsterdam and in 2012 it won the Rotterdam Architecture Prize.

In Hengelo, Koopmans Bouwgroep is rejuvenating the Hengelose Es residential district. It is working with the co-creation concept introduced by ERA Contour: transparent collaboration with all partners and the end users. Under the slogan ‘People make the district’, the residents share their thoughts and ideas for the redevelopment of their homes and neighbourhoods. Most of the current buildings in the district will be demolished to make way for 70 social housing units and 150 owner-occupied units at a wide range of price points. The existing two apartment blocks with 134 units will be thoroughly renovated and the quality of the living environment will also be improved.

Comfort Partners is working with two large housing associations in the province of North Holland as a co-creator to make existing homes structurally safer and more sustainable. In the greater Amsterdam region, more than 3,000 housing units will be fitted with new, sustainable and CO2 safe installations.

Complementary construction and engineering

Engineering and construction are inseparable if renovation and sustainability improvements are to be effective. Comfort Partners, for example, manages and maintains an impressive portfolio of more than 300,000 housing units. The TBI companies benefit from each other’s know-how and expertise in this area. The engineers consider how a home can be made more comfortable and sustainable and meet the occupants’ wishes from a technical point of view.

Another development is that housing associations and other owners are contracting not only building management and maintenance from specialists but increasingly also the settlement of utility bills. They are seeking partners that can carry out all this work for them, from the initial design stage and for decades after completion. Comfort Partners has signed long-term contracts to manage and maintain the buildings and facilities of several housing associations and has committed itself to ensuring they remain in peak condition.

Extension of the renovation concept

The ready-to-use modules of the BETER OP DE METER renovation concept can improve the energy performance of a housing association’s stock quickly and at relatively little cost. The concept was already available for terraced and corner houses and the modular design was extended in 2016 to make it suitable for communal entry flats. With a simple intervention in the form of an integrated prefab façade that holds all the building systems, energy costs can be reduced by between 50% and 80%. With a Nul op de Meter intervention, the Energy Performance Fee (EPF) is also applicable.

BETER OP DE METER is an energy renovation concept from the makers of the Renovation Compass. This is an alliance between the TBI housing companies and the renovation companies Hemubo, Smits Vastgoedzorg and Rutges Vernieuwt. They have been carrying out renovation projects for many years and have pooled their know-how and skills to develop smart products and concepts that answer today’s renovation needs. WTH and Vareno, for example, offer tailor-made heating and cooling solutions for large and small-scale renovation projects.

Repurposing, restoration and maintenance of the built heritage

The challenge in the built heritage sector has fundamentally changed in recent years. Following a decades-long restoration programme initiated by central government, the average maintenance state of the Dutch built heritage is now adequate. The problem now, however, is that a large number of these historic buildings are vacant. Repurposing them can guarantee their continued use.

The contracting company Nico de Bont (a subsidiary of Hazenberg Bouw) restored the St Eusebius church in Arnhem and Park Sorghvliet in The Hague and carried out many repurposing projects during the year. For IDBB Vastgoed in Rosmalen it converted a monastery into a luxury assisted living complex for 25 residents. Together with BOEi the company redeveloped an old varnish factory in Oisterwijk into 25 unique loft apartments, each co-designed with the future occupants. ln Eindhoven it is currently converting a former monastery into 75 loft units for the social housing sector. And in Amsterdam it has started repurposing several historical canalside houses on Herengracht into 28 luxury care home units. Domus Magnus will begin renting them out at the end of 2017.

ERA Erfgoed at work

To relieve the post-war housing need, ERA built flats throughout the Netherlands in the 1960s and 1970s. The ERA flat was the first housing concept that tailored homes to the residents’ wishes. In 2016 ERA Contour and Smits Vastgoedzorg were awarded a contract to renovate three ERA flats in Rotterdam. This major maintenance project will not only improve the flats’ energy performance but will also increase their comfort, health, safety and appearance.
