Everything from A to Z
One team for the whole extension
No two Amsterdam homes are the same, and your extension deserves that same uniqueness. We design and build to measure — from a sleek glass extension to a warm timber addition in canal-house style.
Drawings, calculations & permit
Professional structural drawings and precise calculations, plus the environmental permit application handled for you.
Durable materials, fast delivery
High-quality, durable materials suited to the Dutch climate. Timber additions are eco-friendly, budget-smart and often delivered within a few weeks.
A smart investment
More space without moving
In Amsterdam’s competitive housing market, moving can be costly and stressful. An extension, roof extension or dormer adds valuable square metres and can boost your property’s market value.
Craftsmanship with an eye for detail and sustainability
Whether you dream of a modern extension with plenty of glass for natural light, or a rustic timber addition that blends with the surroundings, the options are broad. We use durable materials so your investment lasts for years.
Stress-free from start to finish
You focus on the result; we take care of permits, materials and planning. Contact us for a free, no-obligation consultation.
