A Complete Service

Our team designs, plans and builds your extension within the agreed timescale and budget. We offer competitive prices and always produce satisfactory results. Both single- and double-storey extensions are available and we can expand narrow kitchens to create a spacious, comfortable kitchen-dining room.

The ENK Construction Ltd team works closely with our clients to design rooms that suit your needs and reflect your personal tastes in the style and décor. 

We can recommend practical installations that maximise every inch of space and create a seamless flow between the main property and extension as well as throughout your expanded living environment.

Available options include:

  • Bungalow Extensions 

  • Glass Extensions

  • Old Building Extensions

  • Over-Structure Extensions

  • Rear-Facing Extensions

  • Rendered Extensions

  • Side-Return Extensions

  • Wraparound Extensions

What We Offer

We construct reinforced foundations and install double- or triple-glazed windows. The reinforced concrete foundations will perform well, providing a great deal of stability even on poor ground. Double and triple glazing will improve insulation, leading to a warmer home with reduced energy bills and good acoustics. 

ENK Construction Ltd is the preferred choice for property extensions in Oxford, Henley-on-Thames and the surrounding areas. 

We have over 35 years of experience, and include a one-year workmanship guarantee and offer an insurance-backed warranty through the FMB on all projects we complete. 

Our Checkatrade-vetted builders also carry out brickwork to keep your home safe from water ingress and other moisture-related issues.

Types of Extensions


If you have a structure like a garage that you wish to extend, our builders can design and implement an over-structure extension, which will sit on top of the garage, providing additional living space without the need to encroach on your garden.


For homeowners with large gardens or outdoor areas that they rarely use, we can construct an extension at the rear of the property. This is commonly used to extend narrow kitchens, creating an open-plan space to prepare food, cook, and socialise with family members.


Is there an unused alleyway at the side of your property? Then why not increase aesthetic appeal and property value by extending your home into this space and creating a larger ground floor.


As large L-shape structures these extensions are built at the side and rear of the property to essentially create a new level with multiple additional rooms and lots of floor space. This structure can be used for guest bedrooms, a utility room or a spacious, comfortable living room.

Here at ENK Construction Ltd, we design, plan and build a variety of property extensions to expand properties across Oxford, Henley-on-Thames and the surrounding areas. 

We are a family-run company that is proud of our reputation for delivering quality end results.
