We take responsibility for every aspect of your garden room project. From initial discussions, a visit to your home and design drawings through to planning permission, foundations and construction everything is taken care of by us. Project management is included in the price of your building.
Foundations for garden rooms
A real building needs real foundations. Time and money invested in foundations are at the core of a well designed garden rooms and offices. So, budget between £3,000 to £5,000 for foundations and bringing electricity to the building.
Gordon Smith, our architect, designed our low impact foundation system which we adjust and fine tune for your particular garden and garden room design. Our foundations aren’t complicated, but are definitely to building regulations standards and very secure. We use local builders to install the foundations. We organise quotations and installation on your behalf.
Design and styling offices and garden rooms
Bespoke designs are all part of our service. Garden rooms can be re-proportioned, ceilings made higher or lower, windows and doors moved and made bigger or made smaller. We will produce a series of drawings until you have got the building you want, along with detailed garden room prices.
Design details can be retro or contemporary. Our architect will help you channel your imagination.
Designing a building that steps outside of our ‘house style’ may incur a design charge if it is complex and requires lots of drawing board time.
Our construction team has built beautiful offices and garden rooms for our customers for many years. They work closely with our architect to produce an craftsman finished project. They are very flexible and are always willing to add little details and afterthoughts.
A top quality garden rooms combine skilled design and craftsmanship with the best materials. The sum is then better than its parts. Mass produced designs, cheap construction materials and cheap wood are false economies. We specify the best, UK sourced materials and this is reflected in the garden room prices you pay for a building that will last a lifetime.
