Wanting more space but not being able to move due to school commitments, this is something we hear a lot from clients and was the case for the owners of this charming family home when they engaged our services. So we set about coming up with a scheme that met their needs to a T! We designed a proposal that fell within the homeowners permitted development rights, we added our signature finishing touches such as french doors in the loft with a juliette balcony and Bi-fold doors in the extension.


When you have made the decision to increase the size of your home, you don't want to be kept waiting, so ask one of our knowledgeable consultants at LCCL construction about our super speedy design services and lets get building! Loft conversion builds have a speedy delivery, with most begin completed with in 4 to 6 weeks. House extensions depending on the size on average take 8 to 16 weeks.



The loft conversion itself consists of a large room which is now classed as the Master Bedroom, meaning the parents were able to move ustairs and have their own complete suite with a large bedroom, juliette balcony and en-suite bathroom. The en-suite is a shower room which is generally what people choose at the moment.


The house extension included structural alterations, Velux skylights, new flooring, new roofs and a striking colourful new kitchen. Our team at LCCL construction was on hand to help our clients through every step of the build and the decision making process as we understand how overwhelming it can be.

To finish off the project we added a 12-month workmanship guarantee and a 10-year LABC structural warranty for assurances.

Quality of Finish: Modern

We supplied all the building materials required todeliver a high quality total finish. Kitchens, flooring, windows and bathrooms are supplied by us through our experienced procurement team, they are well versed in getting everything on site at the right time to prevent delays and ensure a smooth build. Expert installations were completed by the LCCL trades teams in all areas.
