Bespoke SIPs buildings and garden rooms

LaneRow design and build garden rooms, SIPs buildings and extensions. We build using Structural Insulated Panels, SIPS, these create a highly insulated, precision engineered structure which is fast to construct. Our typical garden rooms don't need planning permission and are watertight within a working week.

Working from home is the new reality that many of us are adjusting to and we're quickly finding that mixing home life and work life all in the same building is challenging. A garden room quickly adds space to live: use yours as an office, a playroom, a studio, even a gym or a bar and switch it around anytime you need to.

LaneRow Buildings are not timber frame! We use 150mm SIPs roof, 100mm SIPs walls and floor. We build some of the most thermally insulated buildings on the market. We have high quality materials and attention to build details not found with many other companies. Contact us to find out more and discuss your project.

Irrespective of pandemics, the trend for working from home is steadily increasing as people look for more flexibility in their work life and companies shift work forces out of expensive buildings. Garden rooms are assets that add value to your property. More and more, house buyers look for garden rooms in their search for the perfect property

What are SIPs?

SIPs are Structurally Insulated Panels. Made in the UK a panel combines two skins of strong OSB board with a special injected foam core to give strength and insulation. SIPs are starting to replace old build methods and offer better insulation, quicker build times and healthier structures. SIPs are now used to build houses, commercial buildings and garden rooms. Often a SIPs garden room will have higher insulation qualities than the house it sits beside!

Simon, Paul and the Lanerow team are a joy to work with. They are inspired in their thinking, meticulous in their execution and thoroughly decent in all of their undertakings. It has to be said that that they are also perfectionists which doesn’t usually go hand in hand with a sense of humour and fun outlook on life, but in their case this is true! Their subbies are also first class and share their amazing ethos.The other thing we want to say is that if you are umming and ahing about whether to get a garden office- just do it! The impact that it has had on our quality of life and the way that we think about our work/ business has been extraordinary. We are absolutely delighted with the results. Thanks Guys 👏👏 - Jon B

2 months ago We wanted a garden room as part of makeover of our garden. Paul and Simon from Lanerow were excellent from start to finish. They helped us every step of the way from design decisions, electrics, lights, decoration, etc. The garden room is built from SIPs , to ensure good insulation and Paul and Simon are extremely conscientious, taking great pride in their work, which shows in the end result. We are extremely happy with the end result of a multi use room, built to a very hight standard , which we can use all year round. Paul and Simon are very knowledgable, friendly and hard working and we wouldn’t hesitate to recommend them. Thanks guys! - Micayla B

5 months ago If you want a garden room with a top quality finish, configured to your exact needs and built to last many, many years then these are you guys. Simon and Paul take a very measured, detailed approach to building garden rooms out of SiPs panels, using carefully selected suppliers and in consultation with you from start to finish to make sure it is perfect. They take pride in their product and this shows. I had my room built over winter which was a challenge but they worked through almost all weather conditions to keep progress up and despite some supplier delays due to Brexit managed to complete in good time. Very happy, a multifunctional room that can be used all year round and is an investment that will pay back if I sell the house. On top of it all they are lovely people too! Highly recommend! - Richard D.
