ALUMINIUM FLUSH WINDOWS | MULBARTON NR14
DUCK EGG BLUE ALUMINIUM FLUSH CASEMENTS AT THE OLD HALL, MULBARTON
Painted timber flush casements on this brick range at The Old Hall in Mulbarton, NR14, were due for replacement. The owners wanted a true like-for-like look: flush outer frames, slim sightlines and a duck egg blue colour, without ongoing paintwork. Amber surveyed, manufactured and fitted Eclipse aluminium flush casements in a duck egg blue finish to match the brick and pantile elevations. The job needed planning approval with the council; Amber are experts at this and handled the whole process for the client. The work shown is the aluminium flush window replacement on this Mulbarton building. See Amber’s aluminium windows and casement range for styles and colours.
Property & Location
The Old Hall sits on The Common in Mulbarton, NR14, a well-known Grade II listed country house south of Norwich, between Swardeston, Bracon Ash, Newton Flotman and Hethersett. The windows in this case study are on a red-brick pantile wing of the property, with light-blue timber flush casements before the job and duck egg blue aluminium flush casements after. Mulbarton is in the NR14 area Amber covers as standard from the Hellesdon Park, Norwich showroom, across Norfolk, Suffolk and Cambridgeshire.
Client Brief
The timber flush windows on this Mulbarton brick wing still looked the part, but paint, seals and thermal performance were no longer what the owners wanted. They asked for a like-for-like aluminium flush replacement in a similar duck egg blue, keeping the flush face and brick openings tidy. Because the work sits at The Old Hall, the job needed planning approval from the council. Amber handled the planning side end to end. They asked for:
- Take-out of the existing painted timber flush casements
- Slim aluminium flush casements in a duck egg blue finish
- Like-for-like flush sightlines to suit the brick and pantile elevations
- Planning approval with the council, managed by Amber
- Externally beaded insulating glass as specified on survey
- Brickwork, cills and finishes left tidy at the end of the job

This is a like-for-like timber-to-aluminium flush replacement on a red-brick wing at The Old Hall, Mulbarton NR14. Opening sizes and hardware follow the survey; the photos show flush casements with horizontal glazing bars in duck egg blue. The project required planning approval with the council; Amber are experts at that process and managed the application and liaison so the client did not have to. Slim aluminium from Amber is surveyed, made and fitted by our manufacturing team. Every quote is fixed and follows a free, no-obligation home survey.
Before & After
Before: Painted timber thick flush casements in a light blue on the brick wing, with timber cills and matching blue rainwater goods on parts of the elevation.
After: Slim aluminium flush casements in a duck egg blue finish, same flush face to the brick, slim aluminium frames and modern sealed units. Same openings, same brick, no more timber painting.
Outcome
From the gravel path the brick wing now reads as aluminium flush casements in duck egg blue, not painted timber. The flush face keeps the traditional look The Old Hall elevation needs; aluminium holds the colour and the seals without the maintenance cycle of timber. Planning approval with the council was part of the job, and Amber handled that process as part of the package. Every Amber window is fitted by the in-house team, not subcontracted. Free, no-obligation home surveys are available across Norfolk, Suffolk and Cambridgeshire, including Mulbarton, Swardeston, Bracon Ash, Newton Flotman, Hethersett and the rest of NR14.

FREQUENTLY ASKED QUESTIONS
What is an aluminium flush casement window?
A flush casement sits nearly level with the outer frame, so the face looks closer to a traditional timber flush window than a chunky stormproof uPVC frame. Amber’s current aluminium flush range uses the JTC2000 system with a 75 mm depth, made to BS 4873 and CE marked, and is fitted across Norfolk, Suffolk and Cambridgeshire, including this Mulbarton NR14 project.
Why replace timber flush windows with aluminium?
Timber flush windows can look right on a brick elevation, but paint, swelling and seal failure catch up. Aluminium flush casements keep the slim, flush look with a factory colour finish and modern insulating glass. On this Mulbarton job the brief was explicitly like-for-like flush, not a stormproof replacement.
What is Amber’s aluminium flush system?
Our Aluminium Flush Casement (JTC2000) is a 75 mm aluminium system with externally beaded glazing. The product guide quotes a typical 28 mm IGU U-value of 1.6 W/m²K or BFRC Band B for the standard build; the exact glass and hardware for each opening are confirmed on survey. See Amber’s aluminium windows page for the range.
Did this Mulbarton job need planning approval?
Yes. Window replacement at The Old Hall needed planning approval with the council. Amber are experts with planning and listed-adjacent work across Norfolk and handled the approval process for the client, alongside survey, manufacture and fitting of the aluminium flush casements.
How much do aluminium flush windows cost in Norfolk?
Aluminium flush casements are quoted per opening after survey, because size, colour, glazing bars, cills and access all change the figure. Amber gives a fixed written quote after a free no-obligation home survey from the Norwich showroom.
Does Amber fit aluminium windows in Mulbarton and NR14?
Yes. Amber Home Improvements is a family-run, Norwich-based installer with over 28 years’ experience, FENSA-registered and GGF-accredited. Windows are surveyed, supplied and fitted by the same in-house team across Norfolk, Suffolk and Cambridgeshire, including Mulbarton, Swardeston, Bracon Ash, Newton Flotman, Hethersett and Cringleford. Visit the showroom at Unit 52, Hellesdon Park Road, Norwich NR6 5DR, or book a survey on 01603 672638.
Is this the same as the Blofield aluminium gable job?
No. The Blofield NR13 case study is anthracite aluminium gable glazing with sliding patio doors on a different house. This Mulbarton project is Eclipse aluminium flush casements in a duck egg blue finish, replacing painted timber flush windows on a brick wing at The Old Hall.
