Safe as Houses



If you are looking for reliable, trustworthy and cost-effective building work – from total refurbishments, through extensions and conversions, to alterations and bespoke joinery – please consider asking Cavetto for a fully detailed, without-obligation quote.

We are renowned in the Winchester and south Hampshire area for our transparent and trustworthy way of doing business.  We have particular expertise in working on Listed buildings and in conservation areas, and, rest assured, we bring the same care and attention to detail that these projects demand, to bear on all our work.

Did you know that repairs to Listed buildings often involve such materials as horsehair, lime plaster and chestnut lathes?  We can undertake this work so that it not only completely satisfies the Planning Officer, but also more importantly, delights you in its authenticity and its compatibility with the rest of your property.

The services that we offer include total refurbishments, loft conversions, single or multi-storey extensions, changing your space by knocking through, the enhancement of a single room or area, making a feature of a room or area, kitchen, bathroom and wet-room installations, and bespoke joinery for lounges, dining areas, bedrooms, as well as for commercial and retail needs.
