Marlborough has seen substantial growth since the early 20th century with the council building houses in places such as Chiminage Close, Coldharbour Lane and Lainey’s Close. These properties have now become a staple in the town and boast a heritage style. With local expertise, we can enhance the appearance of both old and new properties in the area, using exact materials and decorative features to seamlessly blend with the local trends.
We’ve found some common trends over time in the local area. Our wood effect uPVC sash windows, composite front doors, aluminium bifold doors and tiled roof conservatories are becoming increasingly popular with Marlborough homeowners. They’re a sure way to add the ‘wow’ factor to your home, whilst retaining the local elegant appearance and improving the performance of your property.
