Home Owner

Smyth and Sons completed renovations on our home and we are so happy. We added a loft and an extension to our small 2 bedroom house, doubling it in size. We also moved a kitchen and living room wall.

Wonderful service. Outdoor wall done in 2 days. I recommend these guys to anyone looking for a top quality job done in good time. Particularly good for landlords with busy tenants, so flexible with time.

Why extend your home?

Adding extra living space allows for increased family quality time, with more space for your family to spend time together. Extending your house can modernise and improve the efficiency of your home, with more people deciding to create open plan kitchen and living areas, making larger sociable spaces.

Extending your home can take many different forms. Take extending upwards – sometimes there’s already a first-floor roof to extend on top of and at other times, people will extend into the loft. Then there are cellar spaces to extend down into, or perhaps one of the most popular – extending to the side of a house with anything from a first and second floor extension to a conservatory or a porch.
