We will arrange an appointment for one of our experienced design surveyors to meet at the project site. The purpose of this initial meeting we will be to carry out a brief survey of the site, discuss the cellar conversion or basement construction project and make appropriate recommendations. We will offer suggestions and ideas for the space to be constructed and provide information to enable you to fully understand the benefits a new basement living space will provide.


Following our visit we will create a computer-aided pre design for your space and work out a budget estimate for your project within a few days.


By now, you have a draft basement conversion design and a budget estimate. You've had a chance to work with us and measure our style and standards of performance. And you have still haven't risked a dime. No other basement company makes this phase of your project this safe and easy. Now you can approve your job and proceed with the next phase… or shop around before you decide.


If the price and product is to your requirements we arrange a detailed survey with an architect to firm up the detail of the cellar conversion and produce scheme design drawings. We will discuss in detail your fitting-out requirements, floor and wall finishes, discuss plumbing, electrical and identify any specialist works that may need to be undertaken.


A Building Permit is required for basement construction, cellar conversion or alteration, unless the changes are strictly cosmetic. With all building work, the owner of the property (or land) in question is ultimately responsible for complying with the relevant planning rules and building regulations (regardless of the need to apply for planning permission and/or building regulations approval or not). Therefore, failure to comply with the relevant rules will result in the owner being liable for any remedial action (which could go as far as demolition and/or restoration). The general advice is to always discuss your proposals with the relevant Local Planning Authority and Building Control Service before starting work. You can apply for planning permission online through the Planning Portal or we can apply in behalf of you by completing the relevant forms, attaching supporting documents and plans and paying the application fee.


Following the approval of your planning application, if your project involves significant structural works, a structural design and calculation may have to be done by an engineer.


When your design is complete, we sit down with you to firm up the detail of the basement construction and make any adjustments so you can be confident with your design and make changes before it's too late. We will than accurately price the approves design which will hopefully form the basis of the contract documents and the works on site.


As soon as the planning phase is finished and you have been provided with an accurate quotation, you can approve your job and proceed with construction … or shop around before you decide.
