Dormer loft conversions in Slough
A dormer introduces an addition to the roof to create a different internal space. Falcon’s loft offer includes dormer conversions, subject to the property and agreed design. Begin with the room use, stair position and existing roof, then discuss the form that can support that brief. For your Slough enquiry, focus on the roof work and occupied rooms below.

Consider usable space alongside the shape of the roof
A dormer is a roof addition; a rooflight conversion works within the existing roof form. Hip-to-gable work changes a hipped end. If an idea combines roof changes, it needs one coordinated design rather than separate assumptions about each element.
Start with the floor below the loft. A stair needs an arrival point upstairs and a workable connection below. Mark rooms or storage that could be affected, then describe the furniture and use of the proposed new room.
Ask the designer to compare the proposed roof form with usable headroom and daylight inside. Include window direction and the relationship with neighbouring roofs. A nearby dormer or an inspirational photograph does not establish permission or suitability for your house.
Include structural work, insulation, ventilation, fire-safety design and any bathroom services in the assessment. The agreed conversion scope is wider than constructing the visible dormer. Combinations or L-shaped ideas need specific discussion; no extra variant is assumed from this page.
Prepare the Slough property brief
Check Slough’s conservation maps, including Upton and Sussex Place.
Show how a new stair would affect the landing while existing bedrooms remain in use. For the Slough roof brief, include access and household arrangements alongside the intended dormer room.
Include the floor below the loft in the occupation brief. Show bedrooms, the landing and the route a new stair might take, then mark spaces the household needs to keep using. Tell Falcon about stored belongings and any previous roof work you know of. Keep those facts separate from assumptions that boarding or an old opening is suitable for the new conversion. The Slough address and any relevant planning information belong with the roof drawings. Discuss design decisions and product choices before asking for a construction sequence. The exercise helps identify the connection between the roof project and everyday life below it, while leaving access protection, structural work and programme decisions to the assessed scope.
Confirm the council using the property postcode and give the designer any relevant map or decision reference. A named area is a starting point for checking this address, not an assessment of the whole town. Treat sketches and examples as discussion material until the property-specific work has been reviewed.
Separate the design, building work and purchases
Our team offers practical guidance on layouts and finishes. Formal drawings and planning work are arranged and coordinated through the design partner. Practical guidance is not the production of architectural drawings; agree the professional scope and fees for your proposal.
Falcon supplies agreed first-fix materials and carries out the agreed building and fitting work. You buy agreed second-fix items, such as kitchen units, bathroom fittings and flooring, with guidance. The quote should say who supplies and fits each item, and how changes will be agreed.
Keep product choices and required delivery dates with the scope. Confirm dimensions and compatibility before buying items that affect preparation or services. If a choice changes, ask how that affects the agreed work before treating it as a like-for-like replacement.
How Falcon organises a projectDefine the budget and the programme together
The cost depends on the assessed scope, existing condition, design and chosen specification. Compare Falcon’s contract price with your total project spend: add homeowner purchases and any professional, application or other fees outside the building quote. Ask for the VAT treatment and exclusions to be explicit.
Time on site is only one part of the programme. Keep design work, property checks and approvals, lead time, procurement and construction separate when discussing dates. Explain any move, school or household commitments as requirements to discuss, not a start or completion date already agreed.
Related Falcon work and project references
Begin the project discussion with drawings and photographs of your own home. Falcon’s photographed extension rooflights are different work from a loft conversion. The main loft page has a labelled stock illustration for inspiration.
Send existing drawings or safely taken property photographs to explain what you have. A finished picture can help describe a preference, but it cannot show the hidden construction or settle which alterations are suitable.
Loft illustration and disclosureWhat to bring to the first conversation
Include your actual property postcode and describe the safe roof photographs, the landing below, room use and any existing roof sections. In the Slough brief, distinguish facts you know from ideas you want assessed. Keep the roof work and occupied rooms below with the drawings, and identify any decisions already made so their effect on the connected work can be discussed.
Say which drawings or decisions already exist and what still needs to be explored. Include the wider project if several services are involved. The enquiry form keeps the page you came from and lets you choose the project type that best describes your current plans.
Does a dormer remove the need to assess the existing roof?
No. The roof, support, stair, usable headroom and the rest of the house still need assessment. Explain the room you need first; the professional design determines how the proposed roof addition and internal layout fit together.
What should I make clear in my Slough roof enquiry?
Show how a new stair would affect the landing while existing bedrooms remain in use. For the Slough roof brief, include access and household arrangements alongside the intended dormer room.
Does this town page establish permission for my project?
No. The property, proposed work and relevant current rules need their own review. Use the linked council resource as a starting point and arrange formal design and planning work through the partner as agreed.
Can I change the project type when I enquire?
Yes. Choose the work you actually have in mind, including Combination / not sure if needed, and enter the real property postcode. The page context helps explain what you were reading; it is not a substitute for your project details.
