About
Design Build London is built off forty years of construction and design experience. We bring architectural design, planning, drawings and construction under one accountable roof, on one contract, one team and one phone number.
Looking to extend, refurbish or build new? Most clients start by asking whether they need an architect or a builder. The honest answer is that you need both, and they ideally should be the same team. That is what we do.
We take you from the very first sketch, through planning permission and building regulations drawings, all the way to the day you walk back through your front door. There is no second architect to brief, no separate contracts administrator to engage and no project manager to chase. We are responsible for all of it.
The same team that designs your home is the team that builds it. That removes the hand offs, removes the finger pointing, and keeps your project on time, on budget and aligned with your vision.
Tap any extension type to see how it works, when it needs planning permission, and what value it can add.
Loft conversion
A loft conversion is the process of transforming an attic or roof space into a functional, liveable room. It is one of the most popular and cost-effective home improvement projects in the UK, and if designed right is capable of adding significantly to a property's overall market value. It can be delivered without planning permission if your house is not listed or in a conservation area.
A single-storey rear extension is a highly popular and cost-effective way to add valuable living space, such as an open-plan kitchen. It is usually easy to obtain planning permission if its size is proportionate to the house and land, whilst certain sizes can be delivered without planning permission if your house is not listed or in a conservation area.
A double storey rear extension is one of the most effective ways to transform your home. It dramatically increases both living space and property value by building across two floors at the back of your house. It will need planning permission and cannot be delivered under permitted development rights.
A single-storey side extension is a highly popular and cost-effective way to add valuable living space without eating into your main garden space. It can be delivered without planning permission if your house is not listed or in a conservation area.
An infill extension fills in a section of land where the rear of a house meets a side return, and is a highly effective way to expand ground floor living areas, create open-plan kitchens, and maximise natural light without sacrificing precious garden space. It can be delivered without planning permission if your house is not listed or in a conservation area.
A wraparound extension fills in a section at the side of a house and continues around the rear of the house and into the garden space. It is a highly effective way to expand ground floor living areas, create open-plan kitchens, and maximise natural light. It will need planning permission and cannot be delivered under permitted development rights.
Permitted development rights are national grants of planning permission that allow homeowners to carry out certain building projects and changes of use without needing to submit a full planning application. They are automatically granted by Parliament rather than local councils as long as your house is not listed or in a conservation area.
The whole process of kitchen refurbishment (which involved electrics and new flooring) was handled superbly and competently. We felt in very safe hands from the very start. And we are truly delighted with the result! Peter's designing and project managing skills were stretched to the limit because of the need for a tight turnaround. He and the team he assembled worked seamlessly to minimise disruption and keep everything going at full speed ahead. I couldn’t recommend Design Build London more highly!

Our experience has been excellent. Sound commercial judgments about the prospective value of a project once completed underly creative thinking. We liked that very much. There was real evidence of lateral thinking to solve a problem working alongside a consideration of the practical implications. Great service, highly recommended.
