Is a sliding door for an extension a good fit for your home in Lerwick?
A few practical points decide whether sliding doors for extensions suit a particular room and opening:
Where an extension in Lerwick faces south or west, ask about solar-control glass, because a wall of glass in a single-storey room can overheat in summer.
When your Lerwick extension is going through Building Control, keep the energy information for the doors to hand, as the inspector may ask for it.
- Agreeing a fitting date with your builder lets the extension be made weathertight on programme, so plastering and flooring can follow without waiting on the doors.
- Being involved at drawing stage means the opening is formed to suit the door, rather than the door being compromised to suit an opening built a few centimetres out.
- Slimline aluminium systems with interlocks typically around 20–25 mm maximise the glass in a new rear wall, keeping the view as open as possible.
Light and sun in Lerwick
In Lerwick the shortest day has roughly 5 h 49 min of daylight and the longest about 18 h 56 min. The noon sun sits near 6° above the horizon in winter and 53° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.

Survey, manufacture and fitting around Lerwick
A surveyor visits your Lerwick home to check the wall, the structure above and the floor levels, and talks through glass and finish. Any building work is planned to the engineer's design, the door is made to the finished opening sizes — typically 6–8 weeks for slimline systems after check survey sign-off — and fitting usually takes 1–2 days, scheduled to the build programme. Lerwick is in an area we cover by arrangement: the survey is still free, and survey dates, delivery and any travel cost for delivery and fitting are confirmed in your quote before you order.
Do you need approval in Lerwick?
A Scottish extension is warrant work: the council approves the design, including its doors and glazing, against the Scottish building standards before building starts.
Which options matter for sliding doors for extensions?

Questions about sliding doors for extensions in Lerwick
Do you fit sliding doors for extensions in Lerwick?
Yes, by arrangement. Lerwick is in an area we cover by arrangement: the survey is still free, and survey dates, delivery and any travel cost for delivery and fitting are confirmed in your quote before you order.
Can you work with my builder and architect?
Yes, working with your builder, architect and structural engineer is the normal way we approach extension doors. We can provide technical details, opening sizes, threshold requirements and fixing information, and attend site for the check survey. Your builder forms the opening and prepares the floor, and our installers fit the doors to the agreed programme.
How much do sliding doors for an extension cost?
Slimline sliding doors for an extension have a guide price of £7,795–£9,495 for a 3.6 m opening and £9,595–£11,695 for a 4.8 m opening, fitted, inc VAT at standard 2.1 m height. Taller doors, extra panels, special glass and flush thresholds move the price. Your written quote after the check survey fixes it.
How do I get a level threshold in an extension?
A level or flush threshold in an extension needs the finished floor level inside to be set relative to the door sill and the outside paving before the screed goes down. Outside, a drainage channel is needed across the threshold so rain cannot run in. Our thresholds guide explains the options.
