The practical details of choosing an accessible granny annexe.
What is The Oak Accessible granny annexe?
The Oak Accessible is a spacious accessible SIP granny annexe with a comfortable bedroom, open-plan kitchen, dining and lounge area, an accessible wet room and practical storage. The final layout and specification are agreed for your project.
Who is The Oak Accessible designed for?
It can suit older parents, wheelchair users or people with reduced mobility who want independent living close to family. The design is assessed against the individual occupant and their daily needs. We discuss the intended use and any access needs before designing the layout.
What accessible features can The Oak include?
The design can include step-free entry, level thresholds, wider door openings, improved circulation, an accessible wet room, easy-access showering and support rails. Required clearances and details are agreed around the occupant, their equipment and the site.
Is The Oak Accessible suitable for living in throughout the year?
The Oak Accessible uses Structural Insulated Panels. Insulation, glazing, heating and ventilation are considered together to create a comfortable annexe for year-round use, with the exact construction and services agreed in the specification.
What size is The Oak Accessible?
There is no fixed published floor area on this page. We discuss furniture, circulation, wheelchair turning space where needed and the available garden area before agreeing the layout and dimensions.
How much does The Oak Accessible cost?
The Oak Accessible is quoted individually. Size, layout, foundations, access, drainage and utility connections, glazing and finishes all affect the cost. Send your postcode, garden photographs and requirements for a tailored quotation.
Do I need planning permission for a granny annexe?
The planning route depends on your property, the proposed building, its position and how it will be used. Self-contained living and sleeping accommodation need careful consideration. We discuss the planning and building-control requirements for your individual proposal before construction.
What does the turnkey service include?
Our turnkey approach can coordinate design, the planning and building-control process, foundations, SIP construction, external finishes, doors and windows, electrics, plumbing, kitchen, bathroom, flooring, decoration and handover. Your quotation confirms the exact inclusions and any exclusions.
Can The Oak be designed around wheelchair use or changing mobility?
Yes, wheelchair use and future mobility needs can be considered from the start. Tell us about the wheelchair or mobility equipment, transfer needs, routines and any professional recommendations so the layout, turning space, kitchen and wet-room details can be discussed individually.
