CBS Renovation · house renovation in het Gooi
Whole-house renovations in which strip-out, insulation, heating, electrics, bathrooms and finishing run as one project, with one contact person and one itemised quotation.
A home renovation rarely stops at one room. Once the floors are up and the walls are open, it makes sense to deal with the insulation, the wiring and the heating at the same time, and to change the layout while the house is empty. In an older house that often means a new floor plan downstairs, a rebuilt bathroom upstairs and windows that are restored rather than replaced.
We carry out a complete renovation as one project. You have one contact person from the survey to handover, and one itemised quotation that puts every part of the work – strip-out, structure, installations, insulation and interior finishing – on its own line, instead of a separate offer from each trade.
The photo shows Meentweg in Bussum, a house from 1914 that we renovated in 2022 in cooperation with a design studio. Further down are three more houses, with what we did in each.

Our projects
Three houses from different decades, each with its own list of work. The cards show what we did; the photos and the full description are on each project page.

A complete renovation works through the house in layers, from the structure to the last coat of paint. These are the parts we carry out, in roughly the order they come up.
A renovation starts with a visit to the house. We go through it room by room: the structure, the state of the wiring and pipes, the insulation and the windows, and what you would like to change about the layout. From that visit we draw up a plan of the work and an itemised quotation, with every part of the renovation priced on its own line.
Most whole-house renovations begin by taking things out: old finishes, partitions and sometimes a wall that has always been in the way. At Meentweg in Bussum we removed the wall between the kitchen and the living room, installed a metal portal frame and joined the garage to the living room. In Kortenhoef the kitchen and living room were laid out afresh.
More about dismantling works
With the house opened up, insulation can go where it is hard to reach later. In the 1905 house in Bussum we insulated the pitched roof with PIR, the facade with PIR and moisture-resistant plasterboard and the crawl space underneath, and fitted HR++ glazing. At Engweg in Laren we insulated the ground floor and the cavity walls and restored every window for HR++ glass.
More about insulation
When the floors are up anyway, underfloor heating can go in with them. In the 1905 house in Bussum we laid it on the ground and first floors and installed a Daikin-Intergas heat pump of 7.4 kW, with solar panels on the roof. At Meentweg in Bussum the underfloor heating runs through the whole house; at Engweg in Laren it has automatic controls.
More about underfloor heating
Wiring and pipes are easiest to renew while walls and floors are open. In the 1905 house in Bussum and in the house in Kortenhoef we replaced the electrical wiring completely, installed a new meter cupboard and renovated the mechanical systems. At Meentweg in Bussum we fitted an exhaust ventilation system and carried out the preparatory work for a heat pump.
More about electrical work
In the bathroom and kitchen, plumbing, electrics, tiling and joinery all meet in a small space. In the 1905 house in Bussum we redesigned the bathroom with a separate bath, a shower and a laundry area, and renovated the guest toilet. In Kortenhoef we renovated the bathroom and the toilet. At Engweg in Laren the kitchen floor joists were reinforced to carry a range cooker.
More about plumbing
The finishing ties the renovation together: plastered walls, paintwork, new floors and the original details worth keeping. At Engweg in Laren we restored and painted the ceiling beams, doors, cupboards, staircase and balustrade. In the 1905 house in Bussum we restored the wooden windows and doors on the front facade, and at Meentweg we made a built-in cupboard and window-seat benches with storage.

How we work
From the first visit to handover, a renovation runs in six steps.
Step 1
We walk through the house with you, look at the structure, the installations and the insulation, and talk about what you want to change and in which order.
Step 2
You receive a plan of the work and a quotation with every part on its own line, so you can see what each choice adds before anything is fixed.
Step 3
Whether a permit is needed depends on the house and on the changes. We check this before work starts and, where one is needed, prepare the drawings and file the application.
Step 4
Materials for the building work and the finishing are ordered and delivered to the house. If you prefer to choose and order some of them yourself, that is possible.
Step 5
We strip out what has to go, adjust the structure, renew the installations, insulate, and finish the rooms. Along the way we report to you on how the work is progressing.
Step 6
The contact person you start with stays with the project until the house is handed over, and the work we have carried out is covered by our guarantee.
How we run a project from the first contact to handover is described in more detail on our work process page.
From the survey to handover you deal with one person, who plans the strip-out, the installations, the insulation and the finishing so that each trade can start where the previous one left off.
After the survey you receive one quotation for the whole house, with each part of the renovation on a separate line, so any change to the plan is easy to trace.
Our team of 75 engineers and tradespeople works six days a week, from the structural work and installations to the plastering and paintwork.
The work we carry out in your house, from the wiring to the finishing, comes with our guarantee.
Our roots go back to 1995. We have completed more than 270 projects for more than 850 clients, and more than half of our work comes from returning clients and their recommendations.
Our office is in Breukelen, at Merwedeweg 5b, and we renovate houses across het Gooi and in the adjoining part of the province of Utrecht. The houses on this page are in Bussum, Kortenhoef and Laren. Every renovation starts in the same way: with a survey at the house, followed by an itemised quotation.
That depends on the house, but a complete renovation usually touches every layer: strip-out and changes to the layout, insulation of roof, walls and floors, glazing, heating, electrics and plumbing, bathrooms and kitchen, and the finishing of each room. In the 1905 house in Bussum it ran from new wiring and a heat pump to restored front windows. The itemised quotation shows what is included for your house.
A renovation has no fixed price per house. The cost depends on the size and condition of the house, how much of the structure and the installations has to change, and the materials and finishes you choose. After a survey at your house you receive a written, itemised quotation with every part of the work on its own line, so you can see what each choice adds and adjust the plan before work starts.
That depends on the house and on the scope of the work, so the planning is made per project. Some examples: the 1905 house in Bussum was renovated between July and October 2024, the house in Kortenhoef between June and September 2024, and the 1914 house at Meentweg in Bussum between June and November 2022. The planning for your house follows from the survey and the quotation.
It can, when insulation and heating are part of the plan. The 1905 house in Bussum went from energy label G to A+++ after we insulated the roof, the facade and the crawl space, fitted HR++ glazing, laid underfloor heating and installed a heat pump and solar panels. What is achievable in your house depends on how it is built and where it starts from, and we look at that during the survey.
Yes. Several of the houses we have renovated date from the early twentieth century. At Engweg in Laren, a house from 1914, we restored every window for HR++ glass, uncovered and restored the original wooden sliding door, and restored the ceiling beams, doors, cupboards and staircase. In the 1905 house in Bussum we restored the wooden windows and doors on the front facade.
Yes. Some renovations call for extra space as well, and we also carry out house extensions and attic renovations, each described on its own page of this site. At Meentweg in Bussum we gained living space inside the existing house by joining the garage to the living room. Whether an extension, an attic conversion or a new layout suits your house best is something we look at during the survey.
Our office is in Breukelen, at Merwedeweg 5b. We work across het Gooi, in towns such as Hilversum, Bussum, Naarden, Huizen, Blaricum, Laren and Eemnes, and in the adjoining part of the province of Utrecht, including Soest and Utrecht. The houses on this page are in Bussum, Kortenhoef and Laren, and every renovation starts with a survey at the house.
