We work with a network of reliable and trusted partners to connect with our clients for their build. We regularly introduce contractors, structural engineers, party wall surveyors, interior designers and more.

Ready To Start When You Are

Why would you want to start a project when there are no drawings to follow, the structural engineering hasn't been completed, party wall matters haven't been closed out with the neighbours and building regulations haven't been considered?

Although many types of extensions and conversions are acceptable under permitted development, commencing building works without thorough checks can result in severe delays and even enforcement to change or take down.

We can ensure that your designs are produced in accordance with policy and if necessary submit a planning or lawful development certificate application to council.
