Our Process

Bespoke conversions, create the perfect space.

Why Choose Us

Are you looking to increase the available living space within your home? Would your loft space be more useful to you as an additional room, than as a dark and dingy storage space for those dusty old boxes?

Good news, we are here to help. Whether you require an extra bedroom due to your family growing or perhaps for a home office, then a loft conversion can be an ideal solution.


We are committed to driving value whilst retaining the highest quality finish


You deal with your own project manager from start to finish, keeping you regularly updated on your work’s progressing


Our team of specialists excel at individually designing each project to suit the existing space and your requirements


We have strong links with local councils and planning consultants to make your project as streamlined as possible

The Process

Each and every conversion and extension that we create is unique and individually designed to make the perfect use of the space available. However, our approach to providing you with your conversion and extension remains consistent to ensure that we are meeting and exceeding the same high standards that we set.

We strive to provide our clients with a hassle-free process, to ensure that each project is completed on time and is of exceptional quality.

1. The Initial Quote
You will speak to Tom, who will be able to discuss your ideas and go through the options available to you in a little more detail to put together your free initial quote. He will visit the property to assess the space available and provide his recommendations. Conversions often vary depending on the age, type and design of your property, so we will be able to advise on what’s likely to suit your home best.
2. The Deposit
Once we have discussed all of the project details and come to an agreement, we will need to take a 5% deposit in order to confirm a date for the works to commence. At this point, our architect will survey the property to begin the design process. Structural drawings and calculations will also be provided alongside the architect’s drawings. Clients are allowed to amend the architect’s drawings until they are happy for them to be submitted to the local planning department.
3. Prior to the Project Commencing
Clients will need to put together party wall agreements to ensure that no disputes arise. We are on hand to assist with this and can provide you with the details of excellent third party surveyors who can help with putting this together. We will also provide details of the work schedule, outlining the work to be completed on each date and the requirements we have.
4. The Project Commences
The average lost conversion takes between seven to ten weeks to complete, depending on the type of conversion that you have opted to go for. Tom will visit frequently to ensure that the work is progressing as planned and is being carried out to our usual high standards. They will be on hand to answer any questions you may have during this time.
5. Final Checks
Once the work has been completed, Tom will carry out a check with the client and will ensure that the electrician provides the Part P certificate for the property. Once this is received, the council will be able to assess the project and issue you with a completion certificate and we will carry out any final checks of our own to sign off the project. We will also provide you with your guarantee.
6. Ongoing Support
If you have any questions once the work has been completed and the final checks have been made, please do not worry. We are on hand to help at any time, should any issues arise. Please give us a call on 020 7438 2043.
