Situated just minutes from the beach with a sea view, Mr R purchased this property with the view to redevelop both the interior and exterior to create the perfect holiday cottage for both long and short term holiday lets.
Upon completion of the new plans for the re-development of the cottage Mr R was looking to achieve a contemporary look with a mixture of grey colours. Originally the property was fitted with UPVC rosewood windows which did not fit with the overall look of the property re-development, the original windows were also looking tired and lacking in energy efficiency.
Planning a complete renovation of this detached bungalow in Criccieth, Wales with a view to modernise both the exterior and interior of the property, creating a large family living space with access to the garden via bi-folding doors. The owner wanted to install brand new grey windows and doors to contrast with the white painted render on the property, having looked around at the grey UPVC units on offer they were not satisfied with the look of the grey foils available on UPVC windows. After looking around on the internet and reading about alu-clad windows on our website they decided a visit to our Heswall showroom was a must. Impressed with the powder coated finish of the aluminium capping externally and the internal finish of the wooden core they decided to go with Rationel alu-clad timber windows throughout the property, with a front door from Rationel and a set of aluminium bi-fold doors from Centor to make the most of the outdoor living space.
After purchasing their new home, our clients were certain they would need to do something with the old conservatory at the rear of the property. In a poor state with lots of rot, draughty windows and a polycarbonate roof that had seen better days, the original timber conservatory was a real cold spot in the house and with the leaky roof and windows it was a completely unusable space. After looking into multiple options, it was clear that the best solution was to keep the original conservatory base and replace the roof, windows and doors with brand new units.

This installation of expansive Rationel windows and doors to complete a rear extension ensured that our client's new space was both light filled and airy, helping to connect their internal living space with their stunning feature garden.
The traditional extension was given a contemporary edge with the installation of black aluminium clad timber windows and doors, while maintaining a cosy and warm interior thanks to the tactile timber inside. Another reason our client opted for this specification was to minimise ongoing maintenance for the future, a benefit of an aluminium clad exterior, so they can spend more time in their fabulous garden and less time on maintenance.
