Frequently asked questions

What kind of property renovations can Black Olive Construction carry out?

We are a specialist design, manage & build company with years of experience in all kinds of properties including contemporary flats, modern family homes, period houses and listed buildings, as well as commercial premises. Whether you need a new kitchen or bathroom, a complete house makeover or a two-storey building extension, we offer the full range of services to deliver a bespoke project.

Do I need an architect?

Architectural services may be needed for larger-scale renovations and structural works including building extensions, as well as planning applications. As a vertically integrated company, Black Olive Construction implement complete design solutions to support our building activities. This includes any architectural design, structural, mechanical and engineering, interior and landscaping design and specifications required to make the concepts into reality.

Will I need planning permission for a property extension?

Most building extensions come under ‘permitted development rights’, meaning no planning consent is needed provided that certain criteria are met. However, it is always advisable to check with the local planning authority and get written confirmation. There are exceptions for listed buildings, leasehold properties and Conservation Areas where planning permission must be obtained. We can guide you through the process of obtaining any consents necessary.

    David BCustomer Brighton

    Back in 2021 Black Olive took over the management of a complicated building project. It wasn't an easy job and the project manager had to deal with some significant but unforseen issues.
    Even several months after completion I was able to contact them for follow-up and the manager dealt with any problems that arose both during and after the work.

    VictorCustomer Brighton

    Black Olive is particularly effective at client liaison, and I have always found that their projects start and finish on time with regular updates on progress in-between.
    Black Olive team has a particular eye for detail, takes care to fully understand the requirements, uses strong initiative to overcome any unforseen difficulties in a variety of creative ways and manages internal and external labour extremely effectively.
